Ambitransitive verbAn ambitransitive verb is a verb that is both intransitive and transitive. This verb may or may not require a direct object. English has many ambitransitive verbs. Examples include read, break, and understand (e.g., "I read the book", saying what was read, or just "I read all afternoon"). Ambitransitive verbs are common in some languages, and much less so in other languages, where valency tends to be fixed, and there are explicit valency-changing operations (such as passive voice, antipassive voice, applicatives, causatives, etc.
Polypersonal agreementIn linguistics, polypersonal agreement or polypersonalism is the agreement of a verb with more than one of its arguments (usually up to four). Polypersonalism is a morphological feature of a language, and languages that display it are called polypersonal languages. In non-polypersonal languages, the verb either shows no agreement at all or agrees with the primary argument (in English, the subject). In a language with polypersonal agreement, the verb has agreement morphemes that may indicate (as applicable) the subject, the direct object, the indirect or secondary object, the beneficiary of the verb action, etc.
Unaccusative verbIn linguistics, an unaccusative verb is an intransitive verb whose grammatical subject is not a semantic agent. In other words, the subject does not actively initiate, or is not actively responsible for, the action expressed by the verb. An unaccusative verb's subject is semantically similar to the direct object of a transitive verb or to the subject of a verb in the passive voice. Examples in English are "the tree fell"; "the window broke".
Valency (linguistics)In linguistics, valency or valence is the number and type of arguments controlled by a predicate, content verbs being typical predicates. Valency is related, though not identical, to subcategorization and transitivity, which count only object arguments – valency counts all arguments, including the subject. The linguistic meaning of valency derives from the definition of valency in chemistry. Like valency found in chemistry, there is the binding of specific elements.
Intransitive verbIn grammar, an intransitive verb is a verb whose context does not entail a direct object. That lack of transitivity distinguishes intransitive verbs from transitive verbs, which entail one or more objects. Additionally, intransitive verbs are typically considered within a class apart from modal verbs and defective verbs. In the following sentences, verbs are used without a direct object: "Rivers flow." "I sneezed." "My dog ran." "Water evaporates when it's hot." "You've grown since I last saw you!" "I wonder how old I will be when I die.
Labile verbIn general linguistics, a labile verb (or ergative verb) is a verb that undergoes causative alternation; it can be used both transitively and intransitively, with the requirement that the direct object of its transitive use corresponds to the subject of its intransitive use, as in "I ring the bell" and "The bell rings." Labile verbs are a prominent feature of English, but they also occur in many other languages. The terminology in general linguistics is not stable yet. Labile verbs can also be called "S=O-ambitransitive" (following R.
Transitive verbA transitive verb is a verb that accepts one or more objects, for example, 'to enjoy' in Donald enjoys music. This contrasts with intransitive verbs, which do not have objects, for example, 'to arise' in Donald arose. Transitivity is traditionally thought of as a global property of a clause, by which activity is transferred from an agent to a patient. Transitive verbs can be classified by the number of objects they require. Verbs that accept only two arguments, a subject and a single direct object, are monotransitive.
Ergative–absolutive alignmentIn linguistic typology, ergative–absolutive alignment is a type of morphosyntactic alignment in which the single argument ("subject") of an intransitive verb behaves like the object of a transitive verb, and differently from the agent of a transitive verb. Examples include Basque, Georgian, Mayan, Tibetan, and certain Indo-European languages (such as Pashto and the Kurdish languages and many Indo-Aryan languages like Hindi–Urdu). It has also been attributed to the Semitic modern Aramaic (also called Neo-Aramaic) languages.
Incorporation (linguistics)In linguistics, incorporation is a phenomenon by which a , such as a verb, forms a compound with its direct object (object incorporation) or adverbial modifier, while retaining its original syntactic function. The inclusion of a noun qualifies the verb, narrowing its scope rather than making reference to a specific entity. Incorporation is central to many polysynthetic languages such as those found in North America, Siberia and northern Australia.
Argument (linguistics)In linguistics, an argument is an expression that helps complete the meaning of a predicate, the latter referring in this context to a main verb and its auxiliaries. In this regard, the complement is a closely related concept. Most predicates take one, two, or three arguments. A predicate and its arguments form a predicate-argument structure. The discussion of predicates and arguments is associated most with (content) verbs and noun phrases (NPs), although other can also be construed as predicates and as arguments.
