In grammar, the prepositional case (abbreviated PREP) and the postpositional case (abbreviated POST) - generalised as adpositional cases - are grammatical cases that respectively mark the object of a preposition and a postposition. This term can be used in languages where nouns have a declensional form that appears exclusively in combination with certain prepositions.

Because the objects of these prepositions often denote locations, this case is also sometimes called the locative case: Czech and Slovak lokál/lokativ/lokatív, miejscownik in Polish. This is in concord with its origin: the Slavic prepositional case hails from the Proto-Indo-European locative case (present in Armenian, Sanskrit, and Old Latin, among others). The so-called "second locative" found in modern Russian has ultimately the same origin.[1]

In Irish and Scottish Gaelic, nouns that are the objects of (most) prepositions may be marked with prepositional case, especially if preceded by the definite article. In traditional grammars, and in scholarly treatments of the early language, the term dative case is incorrectly used for the prepositional case. This case is exclusively associated with prepositions. However, not all prepositions trigger prepositional case marking, and a small group of prepositions which are termed compound mark their objects with genitive case, these prepositions being historically derived from the fusion of a preposition plus a following noun which has become grammaticalised. (Compare English "in front of", "because of".) Note however that many nouns no longer exhibit distinct prepositional case forms in the conversational language.

In the Pashto language, there also exists a case that occurs only in combination with certain prepositions. It is more often called the "first oblique" than the prepositional.

In many other languages, the term "prepositional case" is inappropriate, since the forms of nouns selected by prepositions also appear in non-prepositional contexts. For example, in English, prepositions govern the objective (or accusative) case, and so do verbs. In German, prepositions can govern the genitive, dative, or accusative, and none of these cases are exclusively associated with prepositions.

Sindhi is a language which can be said to have a postpositional case. Nominals in Sindhi can take a “contracted” oblique form which may be used in ergative, dative, or locative constructions without a postposition, or a “full” oblique case ending expressed when forming a postpositional phrase. Differences in these forms are only observed in the plural.[2]

Adpositional case refers to a type of morphological case marking in where case is realized through markers syntactically aligned with the prepositional category (P) in the extended projection of the , functioning to express relational semantics such as spatial location, direction, instrumentality, or other grammatical roles that overlap with those of adpositions. These markers are typically phonologically weak suffixes, distinguishing them from fuller adpositional words, and they emerge as an epiphenomenon of involving P, often within prepositional phrases (PPs) that include subprojections like Place, Path, and Axial Part. In contrast to determiner-related cases (D-cases) like nominative or genitive, which pertain to argument structure and possession, adpositional cases are semantically driven and appear in four primary syntactic contexts: peripheral or uses (e.g., locative expressions), cases selected by verbs (e.g., comitative roles), idiosyncratic selections tied to specific predicates, and core grammatical functions in argument positions. They may exhibit agreement patterns, such as with pronouns in languages like Hungarian, and can interact with factors like or , leading to phenomena like differential marking. Adpositions themselves often serve as case markers by assigning cases to their complements, with variability across languages in whether they impose uniform cases (e.g., dative in prepositional phrases) or multiple cases based on semantics (e.g., accusative or oblique in English or Punjabi). Prominent examples occur in , where adpositional cases blend morphological fusion with postpositional origins; in Hungarian, the suffix -ban/-ben yields forms like kert-ben ('in the garden'), paralleling English in the garden and encoding static within a PP structure. Similarly, the szal in busz-szal ('by bus') or allative -hoz/-hez in anyjá-hoz ('to her mother') illustrate verb-selected and quirky uses, respectively. In Finnish, the adessive -lla appears in talo-lla ('at the house'), while Latin demonstrates historical parallels with ablative assignment under prepositions, as in in urbe ('in the city'). These cases highlight the continuum between inflectional morphology and analytic adpositional strategies, influencing syntactic theories of phrase structure and case assignment.

Definition and Overview

Core Definition

Adpositional case refers to a specialized type of that morphologically marks the complements of adpositions—either prepositions or postpositions—to indicate their syntactic and semantic roles within phrases, such as spatial, directional, temporal, or relational dependencies. These cases are typically realized through inflections on nouns, pronouns, or determiners and are often distinct from other grammatical cases, serving exclusively in adpositional contexts rather than for core verbal arguments. Prepositional case, abbreviated as PREP, applies to the objects of prepositions, which precede their complements and govern specific morphological forms to encode relationships like or . In contrast, postpositional case, or POST, governs the objects of postpositions, which follow their complements and similarly trigger unique case markings for analogous relational functions. Both subtypes unify under the P (adposition head), distinguishing adpositional case from broader systems that handle subject-object relations. Key characteristics of adpositional cases include their potential fusion with adpositions into portmanteau forms or the induction of noun morphology alterations that differ from nominative or accusative paradigms used for primary clausal arguments. Unlike core cases, they emphasize oblique dependencies and may exhibit syntactic decomposition into projections like PlaceP or PathP, reflecting nuanced semantic roles. Basic morphological markers for these cases commonly involve suffixes or inflections activated solely by adpositions, such as dedicated endings that spell out the P-head without applying elsewhere in the noun's paradigm.

Relation to Grammatical Case Systems

Adpositional cases integrate with core grammatical cases, such as nominative and accusative, by often repurposing or deriving from spatial and temporal cases like the locative, while becoming specialized for government by adpositions. In languages with rich case systems, adpositional cases extend the paradigm beyond primary syntactic roles, marking dependencies that align nominals with adpositional heads in phrases expressing location, direction, or other semantic relations. This integration follows typological hierarchies of case markedness, where less frequent semantic cases build upon more basic structural ones, constrained by frequency and phonological erosion over time. Functionally, adpositional cases emphasize semantic relations—such as , direction, or instrumentality—mediated through adpositions, in contrast to the syntactic roles of core cases that primarily identify arguments in relation to verbs (e.g., subject or object). While core cases like accusative signal transitivity and argument structure, adpositional cases operate within adpositional phrases to encode theta-role-like specifications, such as path or place, without directly affecting verbal valence. This distinction highlights adpositional cases' role in nominal extended projections, where they realize abstract syntactic categories like P (place or path) that complement but do not overlap with the D () or φ (agreement) features underlying nominative or accusative marking. Morphologically, adpositional cases manifest as inflectional affixes, clitics, or fused forms on nouns, but their realization is invariably dependent on the selecting adposition, differing from the more autonomous assignment of core cases. For instance, in agglutinative languages, these cases appear as suffixes that concatenate with adpositional elements, subject to post-syntactic phonological rules that may cause or allomorphy. Unlike independent adpositions in analytic languages, adpositional case forms require the presence of a governing adposition to trigger their selection, ensuring they function as bound markers within larger phrases. Adpositional cases are not universal across languages; many employ the same morphological forms for adpositional functions as for other grammatical purposes, or rely entirely on adpositions without dedicated case marking. In analytic languages like English, prepositions such as "of" govern genitive-like relations without requiring case inflections on nouns, reflecting a shift from synthetic case systems to periphrastic constructions. This variation underscores that while adpositional cases enhance expressiveness in fusional or agglutinative systems, their absence does not preclude adpositional encoding of semantic relations, as seen in creoles or isolating languages.

Historical and Typological Background

Origins in Proto-Indo-European

The Proto-Indo-European (PIE) language is reconstructed as having a rich nominal case system, including eight primary cases that encoded spatial, relational, and semantic roles without reliance on adpositions. Among these, the , marked typically by the ending -i in singular forms (or in some paradigms), served as a primary means for expressing static location, such as "in" or "on," distinguishing it from dynamic cases like the ablative. This locative form is considered the progenitor of adpositional cases in many daughter languages, where it specialized over time to govern or fuse with emerging adpositions, particularly as synthetic case systems eroded. The evolution of adpositional cases from involved significant sound changes and analogical leveling, especially drawing from the ablative (marked by -os or -ed) and (marked by -eH) forms, which influenced spatial and instrumental adpositional marking across Indo-European branches. Phonetic erosion in late and early daughter languages led to mergers, such as the Latin ablative combining elements from the PIE ablative, locative, and through (e.g., -o deriving from -o-ed), prompting adpositions to assume these functions to maintain semantic distinctions. Analogical processes further reshaped these forms, as seen in the reinforcement of case endings via postpositional particles in branches like Iranian and Indo-Aryan, where ablative- facilitated the shift toward analytic adpositional constructions. Evidence for these developments is drawn from reconstructed PIE forms, such as the locative -i appearing in spatial adverbs that later grammaticalized into adpositions, influencing systems in Slavic and Celtic branches where locative-like endings persisted in prepositional phrases for static location. For instance, the PIE locative -i is reflected in early forms that evolved into specialized adpositional , as analogical extensions preserved its role amid case loss. Similarly, ablative -ed and instrumental -bʰi (in some paradigms) contributed to adpositional markers through phonetic reduction and , evident in the way these endings combined with particles to form hybrid relational expressions in early Indo-European. A key mechanism in this evolution was the of early postpositions and prepositions from nouns, verbs, or local particles, which "pulled along" associated PIE case forms to create adpositional cases. PIE spatial adverbs, often derived from nominal roots in locative or ablative cases (e.g., particles like ad- or abhi), began combining with nouns bearing these endings, gradually bleaching their lexical content to function as relational heads that governed specific cases. This process, accelerating in daughter languages due to syntactic reconfiguration from free to more fixed configurations, transformed independent particles into adpositions that inherited and specialized the semantic load of PIE cases like the locative and .

Cross-Linguistic Distribution

Adpositional cases are widely attested in languages featuring rich morphological case systems, particularly within the Indo-European family, including such as Russian and Polish, where prepositions commonly govern cases like the genitive, dative, or prepositional, and like Irish, in which prepositions trigger the genitive or dative on their complements. They also occur frequently in , exemplified by , where postpositions govern the oblique or ablative cases to express spatial, temporal, or relational functions. Additionally, adpositional cases appear in certain agglutinative languages, such as Sindhi, which employs a postpositional case alongside oblique forms to mark dependencies with postpositions, and some influenced by similar patterns, where postpositions require accusative or locative suffixes. In contrast, adpositional cases are notably rare or absent in isolating and analytic languages, such as English and , where adpositions function independently without inducing morphological case marking on their nominal complements, relying instead on and for relational interpretation. Typologically, adpositional cases frequently correlate with postpositional constructions in , such as those in the Indo-Aryan branch including Sindhi, where postpositions follow oblique-marked nouns to denote . By comparison, prepositional systems with case government predominate in European languages, aligning with head-initial s and fusional morphology. Based on the World Atlas of Language Structures (WALS), morphological case systems occur in 161 of 261 sampled languages (approximately 62%), with adpositional cases serving as a key mechanism in many of these, especially in languages with six or more cases (84 languages, about 32% of the total sample), often manifesting as specialized forms dedicated to adpositional dependencies.

Structural Types

Prepositional Cases

Prepositional cases denote the morphological markings on noun phrases that function as complements to prepositions, which precede their complements in the linear order of the phrase. This syntactic configuration, known as head-initial, positions the preposition as the head of the prepositional phrase (PP), with case assignment occurring structurally in the head-complement relation. For instance, prepositions may require dative or genitive case on their objects to indicate relational roles, as seen in constructions equivalent to "to the house" where the complement bears dative marking in case-rich languages. Morphologically, prepositional cases frequently involve oblique or locative forms, which are non-nominative inflections signaling dependency on the governing preposition. In fusion processes, the preposition and its assigned case can merge into portmanteau forms, where a single realizes both elements, as in French combinations like du (de + le) for "of the." This pattern arises from phonological realization rules that apply to adjacent functional heads, producing suppletive exponents rather than separate affixes. Semantically, prepositional cases primarily express spatial relations such as containment (in) or support (on), temporal durations (during), or abstract associations (with, by). These functions align with deep semantic roles like locative or instrumental, where the case marking clarifies the complement's thematic contribution to the verb's argument structure. A key variation appears in languages where individual prepositions govern multiple cases based on contextual factors, such as motion versus static position; in German, for example, two-way prepositions like auf ("on") take accusative for directional movement (e.g., toward a surface) and dative for locative stasis (e.g., at rest on a surface). This dual assignment reflects an interplay between semantic features like directionality and the verb's aspectual properties.

Postpositional Cases

Postpositional cases refer to morphological markings on or noun phrases that are governed by postpositions, which are adpositions that follow their complements in the syntactic structure. In this configuration, postpositions typically select oblique cases on their complements to express relational meanings, forming postpositional phrases (PPs) where the postposition heads the projection and the case-marked nominal serves as its complement. This is prevalent in languages with head-final , where the postposition trails the it modifies, contrasting with the head-initial order seen in prepositional systems. The assignment of case by postpositions occurs within the extended nominal projection, often involving between case morphology and determiners for spell-out positions. Morphologically, postpositional cases manifest as suffixes attached directly to the stem, frequently exhibiting patterns such as to assimilate with the stem's vowels, and they may fuse with number markers in agglutinative systems. These suffixes encode spatial or relational roles and can stack in limited ways, allowing multiple case markers in sequence to convey complex relations, though many languages restrict this to a single functional slot per nominal. Postpositions themselves may inflect to agree with pronominal complements while remaining invariant with full nouns, highlighting a distinction between synthetic case suffixes and analytic postpositional forms. Such patterns are common in typologies favoring dependent-marking, where case morphology signals on the dependent rather than the head. Semantically, postpositional cases primarily encode locative, directional, and ablative functions, such as static position, goal-oriented movement, or source-oriented separation, often with an emphasis on or comitative roles that highlight means or accompaniment. These cases contribute to the overall semantics of the PP by specifying path or place substructures, integrating with broader argument realization to mark peripheral adverbial relations or verb-selected arguments. Unlike core structural cases, postpositional cases tend toward semantic specificity, allowing for polysemy across related spatial and temporal domains. Variations in postpositional cases include differential marking based on features like or , where certain postpositions trigger distinct oblique forms for definite versus indefinite complements, or impose plural-specific morphology. In some systems, postpositions function as adjuncts without governing case, relying instead on inherent nominal marking, while others exhibit lexical idiosyncrasies in case selection for particular verbs or nouns. These variations underscore the interplay between morphology and in head-final languages, where postpositions adapt to encode nuanced relational contrasts.

Language-Specific Examples

Indo-European Instances

In , adpositional cases are prominently featured through the , which is obligatorily governed by prepositions to express location, time, or topic. For instance, in Czech, the preposition v (in) combines with the locative form of nouns to indicate static position, as in v domě meaning "in the house." This case exhibits irregularities tied to specific adpositions; for example, na (on/at) may trigger locative for surface location but accusative for direction, showing adposition-specific government. In Russian, the locative—also termed the prepositional case—pairs with prepositions like v (in), na (on), o (about), pri (at), and po (after) to denote enclosed spaces, surfaces, or discourse topics, such as v dome ("in the house") or na stole ("on the table"). A distinctive feature is the "second locative," a specialized form used with v or na for approximately 150 masculine nouns, often denoting time or location, as in v sadu ("in the garden") contrasting with the standard v sade*. Morphological patterns in the Slavic locative vary by stem type and number, with adposition-specific alternations. In Czech, singular locatives typically end in for hard stems (e.g., dom-ě) but -i for soft stems, while plurals use -ích. Russian singulars show -e for hard stems (dom-e) and many soft stems (knig-e), but -u for certain soft masculine stems (les-u), with the second locative employing -u/-ju (e.g., god-u "in the year"); plurals standardize to -ax. Below is a representative table for the locative in Russian (hard stem noun dom "" and soft stem les "," including second locative where applicable):
FormHard Stem (dom)Soft Stem (les)Example Phrase
Singular (standard)dom-eles-uv dom-e ("in the house"); na les-u ("on the forest")
Singular (second locative)N/AN/Av god-u ("in the year")
Pluraldom-axles-axv dom-ax ("in the houses")
These patterns highlight irregularities, such as vowel shifts before certain prepositions like o, which may elide to ob before vowels. In Celtic languages, adpositional cases manifest through fused prepositional pronouns, where prepositions combine morphologically with pronouns to encode case-like functions, often akin to dative. In Irish, this fusion creates inflected forms for person, number, and gender; for example, leis fuses the preposition le (with) and the third-person singular masculine pronoun, yielding "with him" in a dative-like role for indirect objects or possession. Similarly, Scottish Gaelic employs comparable fusions, such as leis for "with him," reflecting a historical dative influence in Insular Celtic. These forms are not segmentable into separate morphemes in all cases—e.g., leis lacks a clear pronominal suffix—but systematically mark agreement features, distinguishing them from analytic constructions in other Indo-European branches. Other Indo-European branches exhibit adpositional cases through preposition-governed obliques. In Ancient Greek, prepositions like apo (from) take the genitive for separation or origin, as in apo hippōn ("from horses"), while en (in) or syn (with) govern the dative for location or accompaniment, e.g., syn kraugē ("with a shout"). Dative prepositions such as para can shift meanings by case: para Kyrō (genitive, "from beside Cyrus") versus para tō Kyrō (dative, "with Cyrus"). In Latin, the ablative case functions adpositionally with prepositions like ab (from/by), de (from/about), ex (out of/from), and cum (with), expressing separation, source, or manner; older forms include e as a variant of ex, as in e senatus consulto ("in accordance with the senate's decree"). Examples include ab militibus ("by the soldiers," agentive ablative) and cum militibus ("with the soldiers," associative). These usages trace to Proto-Indo-European ablaut distinctions, with the ablative conflating locative, instrumental, and separative roles. In , an Iranian language, adpositional cases are realized through the , which is triggered by specific prepositions and contrasts with the unmarked absolute (direct) state used for nominative or absolutive functions. Prepositions such as da (possessive 'of') and pa (instrumental 'by means of') govern the for their objects, marking non-agentive or indirect roles, as in the example "Da Lail dalta pinza kala ter shwal" ('Laila spent five years here'), where Lail appears in oblique form to indicate possession. This "first oblique" variant, often associated with experiencer subjects and prepositions like ta ('to'), further distinguishes it from the absolute state, which appears in agentive contexts such as "Za khat likam" ('I am writing a letter'). Sindhi, an Indo-Aryan language, employs a postpositional that inflects before postpositions, with distinctions between contracted singular forms and fuller realizations. For instance, the "ghar" ('house') takes the contracted oblique "ghar-a" in singular constructions with postpositions denoting location or relation, while the oblique uses "gharan-an" to accommodate postpositional phrases, as in genitive or locative uses. Masculine in the singular oblique often replace endings like "-u" with "-a", whereas append "-an", ensuring compatibility with postpositions across accusative-dative and genitive functions without altering the core stem.

Non-Indo-European Instances

In Turkish, a Turkic language, postpositional locatives function as adpositional cases through agglutinative suffixes that denote spatial relations, such as the locative marker -da/-de/-ta/-te, which indicates 'at', 'in', or 'on'. These suffixes attach directly to nouns as postpositions, governing oblique-like case marking for location, and are subject to , where the vowel assimilates to the preceding stem vowel's frontness or backness for phonological cohesion. For example, "ev-de" ('in the house') harmonizes the suffix vowel with the /e/ of "ev" ('house'), illustrating adposition-triggered morphological adjustments typical in Turkic suffix paradigms. Basque demonstrates adpositional cases through prepositions that govern absolutive or ergative marking on their objects, leading to alternations in ergative-absolutive alignment depending on syntactic context. Most prepositions select absolutive case for objects, but in constructions like with perception verbs, transitive subjects shift from ergative to absolutive, as seen in nonfinite complements: finite "Katu-ek sagu-ak harrapatu dituzte-la ikusi dut" ('I saw that the cats caught the mice', cats-ERG) versus nonfinite "Katu-ak sagu-ak harrapatzen ikusi ditut" ('I saw the cats catching the mice', cats-ABS). This alternation highlights how prepositions interact with the language's structural ergativity, where absolutive displacement occurs under defective tense systems.

Theoretical and Analytical Frameworks

Case Assignment by Adpositions

In linguistic theory, adpositions govern the case of their complements through , whereby an adposition specifies the required morphological case for the it selects, ensuring syntactic and semantic coherence. This mechanism, rooted in government theory, posits that adpositions, as heads of prepositional phrases (PPs), assign case to their complements via structural relations, similar to how verbs assign case in argument structures. For instance, in languages with rich case systems, an adposition like English "to" (in contexts evoking dative relations) subcategorizes for an , as seen in equivalents in German where "zu" requires dative on its complement, such as "zu dem Haus" (to the house). Selectional restrictions further constrain case assignment by enforcing semantic compatibility between the adposition and its complement. Spatial adpositions typically select locative cases to encode position or direction, as in Hungarian where the inessive suffix -ban (realized under a postposition like "a kert-ben," in the garden) aligns with static semantics. In contrast, abstract or adpositions favor genitive cases, reflecting relational meanings like origin or part-whole, evident in Finnish constructions where genitive -n denotes possession under adpositions implying . These restrictions arise from the adposition's inherent semantic features, which filter complements based on thematic roles such as or source. Cross-linguistic variation in case assignment by adpositions highlights differences between synthetic and analytic languages. In synthetic languages like Hungarian and Finnish, government is strict, with adpositions or case suffixes rigidly enforcing a single case per complement due to morphological fusion within the , as in Finnish adessive -lla (at the house) under spatial postpositions. Analytic languages like English exhibit looser government, where adpositions select complements without overt case marking, relying instead on and PP structure to convey relations, though underlying selection persists in semantic interpretation. This contrast stems from parametric differences in how functional projections (e.g., PlaceP) are realized morphologically. Case alternation under adpositions occurs in specific contexts, often tied to frequency and semantic nuances. High-frequency nouns may permit shifts between cases like genitive and partitive with the same adposition, as in Finnish where "ympäri talo-n" (around the house, genitive for bounded space) alternates to "ympäri talo-a" (around in the house, partitive for unbounded extension), driven by corpus-attested patterns in frequent items. Such alternations reflect contextual , where default government relaxes for semantically extended interpretations, modeled via bidirectional constraints in optimality-theoretic frameworks. This phenomenon is more prevalent in languages with flexible case paradigms, allowing adpositions to accommodate varying degrees of specificity.

Role in Universal Dependencies

In the Universal Dependencies (UD) framework, the Case feature primarily serves as an inflectional morphological property of nouns, pronouns, adjectives, and other modifiers to indicate their grammatical role, including cases governed by adpositions. For instance, when a preposition requires a dative form on its nominal complement, the noun is annotated with Case=Dat, reflecting the adposition's syntactic demands. This feature distinguishes core cases (e.g., nominative, accusative) from non-core (e.g., dative, genitive) and locative cases (e.g., locative, ablative), ensuring consistent cross-linguistic annotation of adposition-induced morphology. A specialized subfeature, PrepCase, captures lexical variations in personal pronouns that are sensitive to adpositional , particularly in languages where pronouns alter form based on whether they follow a preposition. Values include Pre for prepositional forms and for non-prepositional ones; for example, in Czech, the dative pronoun jemu receives PrepCase= in verbal contexts, but PrepCase=Pre when governed by the preposition k in k němu ("to him"). This subfeature is not applied to nouns but highlights adpositional influence on pronominal , aiding in the analysis of preposition-specific paradigms in Slavic and . Annotation guidelines in UD emphasize distinguishing adposition-governed cases from those assigned by verbs through dependency relations rather than altering the Case value itself. Nominals dependent on adpositions are labeled with the case relation (e.g., --case--> preposition), whereas oblique arguments of verbs use the obl relation, even if sharing the same morphological case like dative. Fusions, such as case markers, are treated as separate where possible, with the clitic annotated as a case dependent to preserve the adpositional structure; for example, in languages with proclitic prepositions, the clitic receives the case label to the host . Examples from UD treebanks illustrate these conventions. In like Russian, locative cases in prepositional phrases are annotated as Case=Loc on nouns governed by prepositions expressing location, such as v Moskve ("in "), where Moskve depends on v via case. For postpositional obliques in , nouns enter an oblique form (often annotated as Case=Acc) before postpositions like ke ("of"), as in laṛke ke ghar ("the boy's house"), with ghar as the head noun and ke as its case dependent, reflecting the adposition's role in marking possession.
