ComplementizerIn linguistics (especially generative grammar), a complementizer or complementiser (glossing abbreviation: ) is a (part of speech) that includes those words that can be used to turn a clause into the subject or object of a sentence. For example, the word that may be called a complementizer in English sentences like Mary believes that it is raining. The concept of complementizers is specific to certain modern grammatical theories. In traditional grammar, such words are normally considered conjunctions.
Agent (grammar)In linguistics, a grammatical agent is the thematic relation of the cause or initiator to an event. The agent is a semantic concept distinct from the subject of a sentence as well as from the topic. While the subject is determined syntactically, primarily through word order, the agent is determined through its relationship to the action expressed by the verb. For example, in the sentence "The little girl was bitten by the dog", girl is the subject, but dog is the agent.
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.
Functional discourse grammarFunctional grammar (FG) and functional discourse grammar (FDG) are grammar models and theories motivated by functional theories of grammar. These theories explain how linguistic utterances are shaped, based on the goals and knowledge of natural language users. In doing so, it contrasts with Chomskyan transformational grammar. Functional discourse grammar has been developed as a successor to functional grammar, attempting to be more psychologically and pragmatically adequate than functional grammar.
