Compared meaning: unfriendly and aggressive, showing hostility (adjective).

比较义项：不友好、有攻击性，带有敌意或好斗倾向（形容词）。

• hostile

  Hostile is the broader, more common word for an unfriendly, aggressive attitude; it can describe people, animals, environments, or countries, and does not require any actual fighting or arguing.

  hostile是更常用、更宽泛的词，指不友好、有攻击性的态度，可以形容人、动物、环境或国家，并不一定涉及真正的争吵或打斗。

  The dog became hostile whenever strangers approached the yard.

  每当陌生人靠近院子，这只狗就变得充满敌意。

• belligerent 本词

  Belligerent is stronger and more formal, describing someone actively quarrelsome or eager to argue or fight in a specific confrontation; it applies to people, not animals or places.

  belligerent语气更强、更正式，指某人主动挑衅、急于争吵或打架，通常用于具体的冲突场合，一般只用来形容人，不用于动物或场所。

  The belligerent customer shouted angrily at the tired waiter.

  那个好斗的顾客对着疲惫的服务员愤怒地大喊大叫。

Both describe an unfriendly, aggressive attitude. Hostile is broader and more common, describing people, animals, places, or countries, with no real fighting needed. Belligerent is stronger and more formal: a person actively quarrelsome or ready to fight in one situation; it applies only to people.

这两个词都表示带有敌意、好斗的态度，但语气强弱和适用对象不同：hostile更常用、范围更广，可以形容人、动物、环境甚至国家，不一定涉及真正的争吵或打斗；belligerent更正式、语气更强，特指某人在具体场合中主动挑衅、急于争吵或打架，通常只用于人。此处只比较这一义项，不涉及两词的其他用法。
