• attack

  A neutral, general word for a violent action against someone; it can be sudden or planned, physical or verbal, small or large in scale, and is the everyday default term for any assault.

  语气中性、泛指的词，用来描述针对某人的暴力行为；可以是突然的或有预谋的，身体上的或言语上的，规模或大或小，是日常描述“攻击”时最常用的默认词。

  The general ordered a surprise attack at dawn.

  将军下令在黎明发动一次突袭（attack）。

• onslaught 本词

  Emphasizes overwhelming force, ferocity, or relentlessness; often used for a fierce attack or a sudden flood of something unpleasant, such as criticism or questions, and rarely for one small act.

  强调攻势猛烈、凶猛或持续不断；常用来形容一次凶猛的攻击，或形容突然涌来的大量令人不快之事，例如批评或提问的猛攻，很少用于描述单一的小规模行为。

  She braced herself for the onslaught of questions from reporters.

  她做好准备，迎接记者们如潮水般涌来的onslaught（连番提问）。

Attack and onslaught both mean a violent action, but attack is the neutral, everyday word, small or large, physical or verbal. Onslaught stresses overwhelming force and ferocity, or a fierce, often sudden rush of something unpleasant, like criticism or questions, not just one small act.

这两个词都表示“攻击”，但attack是中性、泛指的词，可大可小，可以是身体上的也可以是言语上的；onslaught则强调攻势猛烈、来势汹汹，常用于描述大规模或密集涌来的攻击（如批评、提问的猛攻）。这两个词在词库中都只对应这一个义项，没有需要排除的其他义项。
