Defective verb
In linguistics, a defective verb is a verb that either lacks a conjugated form or entails incomplete conjugation, and thus cannot be conjugated for certain grammatical tenses, aspects, persons, genders, or moods that the majority of verbs or a "normal" or regular verb in a particular language can be conjugated for[citation needed]. That is to say, a defective verb lacks forms that most verbs in a particular language have.
The most commonly recognized[citation needed] defective verbs in English are auxiliary verbs—the class of preterite-present verbs—can/could, may/might, shall/should, must, ought, and will/would (would being a later historical development). Though these verbs were not originally defective, in most varieties of English today, they occur only in a modal auxiliary sense. However, unlike normal auxiliary verbs, they are not regularly conjugated in the infinitive mood. Therefore, these defective auxiliaries do not accept each other as objects. Additionally, they do not regularly appear as participles.
For example, can lacks an infinitive, future tense, participle, imperative, and gerund. The missing parts of speech are instead supplied by using the appropriate forms of to be plus able to. So, while I could write and I was able to write have the same meaning, I could has two meanings depending on use, which are I was able to or I would be able to. One cannot say *I will can, which is instead expressed as I will be able to. Similarly, must has no true past tense form, this instead being supplied by had (the past tense of have), and "to have to" in the infinitive, an example of composite conjugation. The past tense expressing the obligatory aspect of must is expressed as "had to", as in He had to go. "Must have", on the other hand, expresses probability or likelihood in modern English; for example, "If that's thunder, there must have been lightning."
Some verbs are becoming more defective as time goes on; for example, although might is etymologically the past tense (preterite) of may, it is no longer generally used as such (for example, *he might not go to mean "he was forbidden to go"). Similarly, should is no longer used as the past of shall, but with a separate meaning indicating possibility or moral obligation. (However, the use of the preterite form should as a subjunctive form continues, as in If I should go there tomorrow, ..., which contrasts with the indicative form I shall go there tomorrow.) The defective verb ought was etymologically the past tense of owe (the affection he ought his children), but it has since split off, leaving owe as a non-defective verb with its original sense and a regular past tense (owed).
Beyond the modal auxiliaries, beware is a fully defective verb in current Modern English: its only, unmarked form is regularly used (in simple aspect, active voice) in the infinitive (I must beware of the dog), imperative (Beware of the dog, [Let the] buyer beware) and subjunctive (She insists that he beware of the dog), but too much of the finite indicative mood is formally lacking (all simple past *bewared, one simple present *bewares, all aspects *am bewaring, etc.). The word begone is similar: any usage other than as an imperative is highly marked. Another defective verb is the archaic quoth, a past tense which is the only surviving form of the verb quethe, "to say" (related to bequeath).
Impersonal verbs such as to rain and to snow share some characteristics with the defective verbs in that forms such as I rain or they snow are not often found; however, the crucial distinction is that impersonal verbs are "missing" certain forms for semantic reasons—in other words, the forms themselves exist and the verb is capable of being fully conjugated with all its forms (and is therefore not defective) but some forms are unlikely to be found because they appear meaningless or nonsensical.
Nevertheless, native speakers can typically use and understand metaphorical or even literal sentences where the "meaningless" forms exist, such as I rained on his parade or She doesn't frost cakes, she snows them.
Contrast the impersonal verb rain (all the forms of which exist, even if they sometimes look semantically odd) with the defective verb can (only I can and I could are possible). In most cases, a synonym for the defective verb must be used instead (for example, "to be able to"). (The forms with an asterisk ⟨*⟩ are impossible, at least with respect to the relevant sense of the verb; these phonemes may by coincidence be attested with respect to a homograph [as with "canning" = "the act of preserving and packaging in cans"].)
