fight

Compared meaning: to work hard against difficulty (verb).

比较义项：为克服困难、对手或不利处境而努力奋斗（动词）。

• contend

  Formal and often literary; typically used with 'with' to mean cope with or deal with a difficult situation or force, rather than a specific person; less common in casual speech.

  较为正式、书面化；常与 with 连用，表示应对或处理困难的处境或压力，而非针对某个具体的人；口语中较少使用。

  As mayor, she must contend with budget cuts and public criticism at once.

  作为市长，她必须同时应对预算削减和公众的批评。

• fight 本词

  Implies direct, often aggressive or forceful conflict against a specific opponent, physical or verbal; more informal and vivid than contend, and less about inner difficulty than struggle.

  强调针对某个具体对手、往往带有攻击性或激烈色彩的直接对抗，可以是肢体上的或言语上的；比 contend 更口语、更生动，也不像 struggle 那样侧重内心的艰难。

  两只狗在公园里为了一根骨头打了起来。

• struggle

  Emphasizes prolonged effort and difficulty with an uncertain outcome, often personal, emotional or financial hardship; commonly followed by 'with' or 'to' plus a verb.

Contend, fight, and struggle all mean to work against difficulty. Contend is formal, with 'with', for coping with a situation. Fight implies direct, forceful conflict against an opponent. Struggle stresses effort with an uncertain outcome. Contend meaning 'to compete for a prize' is not compared.

这三个词都可表示为应对困难、对手或不利处境而努力奋斗，但语气强度和正式程度不同；这里不比较 contend 表示“为奖项、头衔等而竞争”的用法（如 contend for the championship）。
