idiom

Compared meaning: a group of words with a particular meaning (noun).

比较义项：由若干词构成、整体具有某种意义的词组（名词）。

• phrase

  Phrase is a neutral, general term for a short multi-word unit with a particular meaning; it does not imply the meaning is figurative or different from what the individual words suggest.

  phrase 是一个中性、通用的说法，指由几个词构成、整体具有某种意义的短语；它并不暗示该意义是比喻性的，也不表示其含义不同于各个词本身的意思。

  Good morning is a simple phrase people use as a greeting.

  “早上好”是人们用作问候语的一个简单短语。

• idiom 本词

  Idiom specifically means a fixed expression whose overall meaning cannot be guessed from its individual words; it is always figurative, never literal.

  idiom 特指一种固定表达，其整体意义无法从其中各个词的意思推断出来；它总是比喻性的，而非字面意思。

  Break a leg is an idiom that has nothing to do with actually breaking a leg.

  “Break a leg”是一个习语，与真的摔断腿毫无关系。

Phrase and idiom both name a group of words with one meaning. Phrase is neutral and general, not implying anything beyond the literal words. Idiom specifically means a fixed expression whose meaning cannot be guessed from the individual words; it is always figurative.

phrase 和 idiom 都指由几个词组成的词组，容易被学习者混淆；但 idiom 特指意义无法从字面词义推断出来的固定习语，而 phrase 是中性说法，不暗示字面之外的含义。
