Grade 8 Grammar Lesson 29 Causatives: make, get and have
When we use ‘make’ or ‘have’ as the causative verb, we use a plain infinitive, and not a to infinitive verb.
There is no difference in structure between make and have. But the meaning is slightly different. When we use have as a causative verb, there is no use of compulsion, force or authority. The subject might use some other means such as persuasion, request etc.
When we use ‘get’ as the causative verb, we use a to infinitive verb.
The meaning is similar to that of have i.e. no use of force, compulsion or authority.
