Syntactic ambiguity
Syntactic ambiguity, also known as structural ambiguity, amphiboly, or amphibology, is characterized by the potential for a sentence to yield multiple interpretations due to its ambiguous syntax. This form of ambiguity is not derived from the varied meanings of individual words but rather from the relationships among words and clauses within a sentence, concealing interpretations beneath the word order. Consequently, a sentence presents as syntactically ambiguous when it permits reasonable derivation of several possible grammatical structures by an observer.
In jurisprudence, the interpretation of syntactically ambiguous phrases in statutory texts or contracts may be done by courts. Occasionally, claims based on highly improbable interpretations of such ambiguities are dismissed as being frivolous litigation and without merit.[citation needed] The term parse forest refers to the collection of all possible syntactic structures, known as parse trees, that can represent the ambiguous sentence's meanings. The task of clarifying which meaning is actually intended from among the possibilities is known as syntactic disambiguation.
A globally ambiguous sentence is one that has at least two distinct interpretations and where reading the entire sentence does not resolve the ambiguity. Globally ambiguous sentences exist where no feature of the representation (i.e. word order) distinguishes the possible distinct interpretations. Global ambiguities are often unnoticed because readers tend to choose the interpretation they understand to be more probable. One example of a global ambiguity is "The woman held the baby in the green blanket." In this example, the baby, incidentally wrapped in the green blanket, is being held by the woman, or the woman is using the green blanket as an instrument to hold the baby, or the woman is wrapped in the green blanket and holding the baby.
A locally ambiguous sentence is a sentence that contains an ambiguous phrase but has only one interpretation. The ambiguity in a locally ambiguous sentence briefly stays and is resolved, i.e., disambiguated, by the end of the speech. Sometimes, local ambiguities can result in "garden path" sentences, in which a structurally correct sentence is difficult to interpret because one interpretation of the ambiguous region is not the one that makes most sense.
Aristotle writes about an influence of ambiguities on arguments and also about this influence depending on either combination or division of words:
... if one combines the words 'to write-while-not-writing': for then it means, that he has the power to write and not to write at once; whereas if one does not combine them, it means that when he is not writing he has the power to write.
— Aristotle, Sophistical refutations, Book I, Part 4
Newspaper headlines are written in a telegraphic style (headlinese) which often omits the copula, creating syntactic ambiguity. A common form is the garden path type. The name crash blossoms was proposed for these ambiguous headlines by Danny Bloom in the Testy Copy Editors discussion group in August 2009. He based this on the headline "Violinist linked to JAL crash blossoms" that Mike O'Connell had posted, asking what such a headline could be called. The Columbia Journalism Review regularly reprints such headlines in its "The Lower Case" column, and has collected them in the anthologies "Squad Helps Dog Bite Victim" and "Red Tape Holds Up New Bridge". Language Log also has an extensive archive of crash blossoms, for example "Infant Pulled from Wrecked Car Involved in Short Police Pursuit".
