🔧 Grammar B2-24: Causative: consolidation

B1 taught one member of this family — have something done — and left the other four unopened. This consolidation gathers all five and sorts them by the single question that decides the shape of the sentence: is the object a thing or a person? A thing pulls a past participle to the end; a person pulls an infinitive, and then meaning decides which one — make for force, let for permission, have for an instruction to somebody whose job it is, and get for a result won by persuasion, the only member that keeps its to. A two-axis table sets the five side by side, and a second table runs the whole tense and modal range across one building project, so that the rule the tense always sits on have or get is seen rather than stated. The have and get contrast gets its own compared pair and verdict: not a grammar difference but a register and effort difference, which is why a text message says we finally got the wiring replaced and an insurance claim does not. A dedicated section then handles the passive of make, where the swallowed to comes back — was made to wait — together with the fact that let has no passive at all and hands the job to be allowed to. The context text follows a studio relocation in which the narrator arranges everything and builds nothing, with ten tappable forms. Practice runs to thirty-six multiple-choice items across five sets, a twelve-line sorter, six repairs and five trap boxes, every answer carrying its reason.
