temper

Compared meaning: a person's emotional state or feeling (noun).

比较义项：心情、情绪状态（名词）。

• mood

  Mood is a temporary emotional state that can be good, bad or anywhere in between, and often shifts within a day; it does not specifically imply anger. Common: 'in a good/bad mood'.

  mood 指某一时刻的情绪状态，可好可坏，且常在一天之内发生变化；并不特指愤怒。常见搭配：“in a good/bad mood”（心情好/不好）。

  Good music can quickly improve your mood after a stressful day.

  紧张劳累的一天后，好音乐能很快改善你的心情。

• temper 本词

  Temper mainly refers to a tendency to get angry easily rather than a general feeling, and appears in fixed phrases like 'lose your temper', 'keep your temper', 'a quick/bad temper'.

  temper 主要指容易发怒的脾气秉性，而非泛指某种情绪状态，常见于“lose your temper”（发脾气）、“keep your temper”（忍住怒气）、“a quick/bad temper”（脾气急/坏）等固定搭配。

  He has a quick temper and often snaps over minor annoyances.

  他脾气急躁，常常因为一些小烦恼就发火。

Mood and temper both translate as 'mood', but they differ. Mood is a temporary emotional state, good or bad, that changes quickly. Temper focuses on a tendency to get angry, as in 'lose your temper'. Temper's other senses, like metal hardness, are not compared here.

两词词典中都译为“心情”，但实际用法不同：mood 指某一时刻的情绪状态，好坏皆可，且变化较快；temper 更侧重容易发怒的脾气秉性，常见于“发脾气”“忍住怒气”等搭配。这里不比较 temper 表示“金属韧性、回火”或动词“调和、缓和”等其他意义。
