- 1必然結果（數學課上叫「系理」）
A corollary is something that follows straight from something else: once the first thing is true, this extra thing is true as well, almost for free. It is a formal, word. In maths, a corollary is a short extra result that drops out of a bigger proof, without much new work. In careful English, people say “A corollary of this is…” to mean “so this other thing follows”. You would not use it for a simple everyday result like “I was late, so I missed the bus”. A corollary feels like a logical next step, not just what happened next. The word started as a little extra gift: in Latin, extra money paid for a small garland, then a little extra conclusion.
組成From Late Latin corōllārium (“gift; extra; deduction”), from corōlla (“small garland”), the diminutive of corōna (“crown”). First a little extra payment for a garland, then a little extra result.
