Verb phraseIn linguistics, a verb phrase (VP) is a syntactic unit composed of a verb and its arguments except the subject of an independent clause or coordinate clause. Thus, in the sentence A fat man quickly put the money into the box, the words quickly put the money into the box constitute a verb phrase; it consists of the verb put and its arguments, but not the subject a fat man. A verb phrase is similar to what is considered a predicate in traditional grammars.
CausativeIn linguistics, a causative (abbreviated ) is a valency-increasing operation that indicates that a subject either causes someone or something else to do or be something or causes a change in state of a non-volitional event. Normally, it brings in a new argument (the causer), A, into a transitive clause, with the original subject S becoming the object O. All languages have ways to express causation but differ in the means. Most, if not all, languages have specific or lexical causative forms (such as English rise → raise, lie → lay, sit → set).
Passive voiceA passive voice construction is a grammatical voice construction that is found in many languages. In a clause with passive voice, the grammatical subject expresses the theme or patient of the main verb – that is, the person or thing that undergoes the action or has its state changed. This contrasts with active voice, in which the subject has the agent role. For example, in the passive sentence "The tree was pulled down", the subject (the tree) denotes the patient rather than the agent of the action.
