“交战国”常见的英文表达是 “belligerent nation” 或更简洁的 “belligerent”(当上下文明确指的是国家时)。此外,也可以用 “warring state” 来表达。
belligerent:形容词,意为“好战的;交战的”;名词形式指“交战国;好战者”。
warring state:直接翻译为“交战国”,更侧重于描述处于战争状态的国家。
例句:The belligerent nations are required to adhere strictly to the rules of war.(交战国被要求严格遵守战争规则。)
During the war, several warring states were involved in the conflict.(战争期间,有几个交战国卷入了这场冲突。)
