Causative Verbs

Causative verbs let you talk about making things happen—whether you do it yourself, get someone else to do it, or compel an outcome. They answer the question who causes what to happen? rather than who performs the action?. In English this often means the subject of the sentence is not the one carrying out the verb; they are the one arranging, allowing, or forcing it.

The core causative pattern is straightforward: subject + causative verb + noun + verb. The causative verb carries the tense, while the second verb appears in one of two forms depending on which causative you choose. This split is the single most important thing to learn, because getting it wrong produces sentences that sound unmistakably non-native.

Three causatives demand the bare base form (no to): have, make, and let. The pattern is crisp: She had him prepare finger foods. They made me wait outside. Let her go. In each case the person after the causative verb is the one who actually performs the second action. These three are so common in everyday speech that you will hear them constantly: I'll have my assistant send the file, Don't make me repeat myself, Let me help you with that.

All other causatives take the full infinitive with to: force, require, allow, enable, cause, get, keep, permit. You say He forced her to sign the contract, never He forced her sign. Similarly: This feature enables users to search faster, She got him to agree to the deal. The one tricky member is get, which insists on the infinitive despite feeling as informal as have. This is a common error: learners hear have someone do and carry the pattern over to get someone do, but the correct form is always get someone to do.

There is one important exception: in the passive voice, make flips to the infinitive. Active: They made him apologize. Passive: He was made to apologize. This is unique to make and catches many advanced learners off guard.

A second causative pattern uses past participles to describe services performed by someone else. With have and get, you can say I had my car washed or She got her hair cut. Here the noun receives the action, and who performed it is implied or irrelevant. This form is especially useful for errands, repairs, and personal services. Note that get tends to feel slightly more effortful than have: I finally got the roof repaired suggests persistence.

Causative verbs sit at the intersection of several grammar topics. They overlap with Factitive Verbs—which describe a change of state rather than an action caused—and with the Passive Voice, which shares the past-participle pattern for services. Understanding causatives unlocks a huge range of natural expression, from assigning tasks to describing what you had done at the salon.
