causative meaning
ENWCausative
- In linguistics, a causative (abbreviated CAUS) is a valency-increasing operation that indicates that a subject causes someone or something else to do or be something, or causes a change in state of a non-volitional event.
- All languages have ways to express causation, but differ in the means. Most, if not all languages have lexical causative forms (such as English rise → raise, lie → lay, sit → set).
- Note that the prototypical English causative is make, rather than cause. Linguistic terms traditionally are given names with a Romance root, which has led some to believe that cause is the more prototypical.
