- 1先決條件；學校選課說的「先修」
A prerequisite is something you must have or do before something else can happen. Schools love it: Calculus is a prerequisite for Physics 2 — you cannot take the second class until you have passed the first. Jobs use it too: three years’ experience as a prerequisite. As an adjective: a prerequisite skill, a prerequisite course. It is a formal, slightly stiff word; in easy talk people say “you need this first” or “you have to do this before.” Though actually people stretch it. A true prerequisite is a gate: without it, the next step is not allowed or not possible. People also say it for things that merely help a lot (“a good night’s sleep is a prerequisite for a clear head”), which is looser, more like strong advice. In course catalogues it is the strict sense.
From the word’s history
pre- + requisite.
pre-「之前」加 requisite「必需的」。
組成pre- (before) + requisite (needed, required).
