- 1n/ˈkætəɡɔːri/ · /ˈkætəɡəri/類別／種類
A group of people or things that have something important in common, used to help organize or sort them.
「category」是指「把東西分組的方式」——把有共同特徵的人或物放在同一個類別裡。例如 Animals can be divided into categories（動物可以分成幾個類別）。它比 type 或 kind 更正式，常出現在學術、商業或分類系統中。可以想成一個「整理用的大箱子」，同一類的東西放在同一箱。

categorynoun/ˈkæt.ɪ.ɡ(ə.)ɹi/

A group, often named or numbered, to which items are assigned based on similarity or defined criteria.
- This steep and dangerous climb belongs to the most difficult category.

mathematicssciencesA collection of objects, together with a transitively closed collection of composable arrows between them, such that every object has an identity arrow, and such that arrow composition is associative.
- One well-known category has sets as objects and functions as arrows.
- Just as a monoid consists of an underlying set with a binary operation "on top of it" which is closed, associative and with an identity, a category consists of an underlying digraph with an arrow composition operation "on top of it" which is transitively closed, associative, and with an identity at each object. In fact, a category's composition operation, when restricted to a single one of its objects, turns that object's set of arrows (which would all be loops) into a monoid.
