If something necessitates an action, it makes that action necessary: you do not really have a choice. A storm necessitates a change of route; an injury may necessitate a long rest. This is a formal, written kind of word. In everyday talk people say mean we have to, force us to, or mean that we need to. Though actually, you almost never hear a person as the subject in the sense of “I necessitate a break.” It is the situation, the rule, the injury, the weather that necessitates something. It is colder than need: need can be a feeling; necessitate is about what the facts require.
使必須；使有必要
組成From Latin. The old verb necessitō meant “to make necessary,” from necessitās (necessity, need). That comes from necesse (unavoidable), built from ne- (not) + cessus (given up, yielded). English uses the verb ending -ate.
