A transitive verb is a verb that requires one or more objects in a sentence. The term is used to contrast with intransitive verbs, which do not have objects in a sentence.
Philosophy of language is concerned with four central problems: the nature of meaning, language use, language cognition, and the relationship between language and reality. For continental philosophers, however, the philosophy of language tends to be dealt with, not as a separate topic, but as a part of logic (see the section "Language and continental philosophy" below).
First and foremost, philosophers of language prioritize their inquiry on the nature of meaning. They seek to explain what it means to "mean" something. Topics in that vein include the nature of synonymy, the origins of meaning itself, and how any meaning can ever really be known. Another project under this heading of special interest to analytic philosophers of language is the investigation into the manner in which sentences are composed into a meaningful whole out of the meaning of its parts. Semantics
In linguistics, an ergative verb is a verb that can be either transitive or intransitive, and whose subject when intransitive corresponds to its direct object when transitive.
An auxiliary verb is a verb that adds functional or grammatical meaning to the clause in which it appears—for example, to express tense, aspect, modality, voice, emphasis, etc. Auxiliary verbs usually accompany a main verb. The main verb provides the main semantic content of the clause. An example is the verb have in the sentence I have finished my dinner. Here, the main verb is finish, and the auxiliary have helps to express the perfect aspect. Some sentences contain a chain of two or more auxiliary verbs. Auxiliary verbs are also called helping verbs, helper verbs, or (verbal) auxiliaries. They may be glossed with the abbreviation AUX.
