• short

  Occurs only inside fixed phrasal verbs such as 'cut somebody short' or 'stop short', meaning to interrupt or halt abruptly; it cannot freely modify other verbs the way 'suddenly' can.

  只出现在固定的动词短语中，如“cut somebody short”（打断某人）或“stop short”（突然停下），表示突然中断或停止；它不能像suddenly那样自由修饰其他动词。

  She cut him short before he could finish his explanation.

  她在他还没解释完之前就突然打断了他。

• suddenly 本词

  A general-purpose adverb that can modify almost any verb to show something happens quickly and unexpectedly; much more common and flexible than 'short'.

  是一个通用副词，几乎可以修饰任何动词，表示某事发生得很快、出乎意料；比short更常用，用法也更灵活。

  The dog suddenly barked and everyone in the room jumped.

  那只狗突然叫了起来，屋里的人都吓了一跳。

Short and suddenly both can mean abruptly, but short only appears in fixed phrases like 'cut someone short' or 'stop short'. Suddenly is a general adverb that can modify almost any verb, showing quick, unexpected action. Short's senses 'small' or 'brief' are not compared.

这两个词在“突然”这一意义上意思相近，但short仅出现在少数固定动词短语中（如cut somebody short、stop short），表示突然打断或停止，不能自由搭配其他动词；suddenly则是通用副词，几乎可以修饰任何动作，使用范围更广、更常见。这里不比较short表示“短的、矮的”或“简短的”等其他常见意义。
