Causative verbs designate the action necessary to cause another action to happen. In "The devil made me do it." the verb "made" causes the "do" to happen. Here is a brief list of causative verbs, in no particular order: let, help, allow, have, require, allow, motivate, get, make, convince, hire, assist, encourage, permit, employ, force. Most of them are followed by an object (noun or pronoun) followed by an infinitive: "She allows her pet cockatiel to perch on the windowsill. She hired a carpenter to build a new birdcage."

Three causative verbs are exceptions to the pattern described above. Instead of being followed by a noun/pronoun and an infinitive, the causative verbs have, make and let are followed by a noun/pronoun and the base form of the verb (which is actually an infinitive with the "to" left off).
