CAUSATIVE VERBS

In linguistics, a causative (abbreviated caus) is a form 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 they differ in the means. In some languages there are morphological devices (such as inflection) that change verbs into their causative forms, or adjectives into verbs of "becoming". Other languages employ periphrasis, with idiomatic expressions or auxiliary verbs. All languages also have lexical causative forms (such as English rise → raise).
Causative Verbs

This sentence is similar in meaning to: Someone painted Jack's house. OR Jack's house was painted by someone. Causative verbs express the idea of someone causing something to take place. Causative verbs can be similar in meaning to passive verbs.
Examples:

Both 'make' and 'have' can be used as causative verbs.
