Inverse copular constructionsIn linguistics, inverse copular constructions, named after Moro (1997), are a type of inversion in English where canonical SCP word order (subject-copula-predicative expression, e.g. Fred is the plumber) is reversed in a sense, so that one appears to have the order PCS instead (predicative expression-copula-subject, e.g. The plumber is Fred). The verb in these constructions is always the copula be (am, are, is, was, were). Inverse copular constructions are intriguing because they render the distinction between subject and predicative expression difficult to maintain.
Complement (linguistics)In grammar, a complement is a word, phrase, or clause that is necessary to complete the meaning of a given expression. Complements are often also arguments (expressions that help complete the meaning of a predicate). In many non-theoretical grammars, the terms subject complement (also called a predicative of the subject) and object complement are employed to denote the predicative expressions (predicative complements), such as predicative adjectives and nominals (also called a predicative nominative or predicate nominative), that serve to assign a property to a subject or an object: Ryan is upset.
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.
Subject complementIn grammatical terminology, a subject complement is a predicative expression that follows a linking verb (copula) and that complements the subject of a clause by either renaming or describing it. It completes the meaning of the subject. In the former case, a renaming noun phrase such as a noun or pronoun is called a predicative nominal. An adjective following the copula and describing the subject is called a predicative adjective. In either case the predicative complement in effect mirrors the subject.
Control (linguistics)In linguistics, control is a construction in which the understood subject of a given predicate is determined by some expression in context. Stereotypical instances of control involve verbs. A superordinate verb "controls" the arguments of a subordinate, nonfinite verb. Control was intensively studied in the government and binding framework in the 1980s, and much of the terminology from that era is still used today. In the days of Transformational Grammar, control phenomena were discussed in terms of Equi-NP deletion.
Split ergativityIn linguistic typology, split ergativity is a feature of certain languages where some constructions use ergative syntax and morphology, but other constructions show another pattern, usually nominative–accusative. The conditions in which ergative constructions are used varies among different languages. Ergative–absolutive alignment Nominative–accusative languages (including European languages, with the notable exception of Basque) treat both the actor in a clause with a transitive verb and the experiencer in a clause with an intransitive verb in the same way grammatically.
