  The fellow standing behind me in line offered to hold my coffee.

• lad

These are informal British words for a man. Fellow is neutral and slightly formal. Lad means a young man. Chap is old-fashioned and gentlemanly. Bloke is very casual, for an ordinary man. Fellow can also mean 'of the same group' (fellow students); not compared here.

这几个词都是英式英语中对“男人”的非正式称呼，彼此意思相近、容易混淆，但语域和联想色彩不同：lad 突出“年轻”，chap 略显绅士、老派，bloke 更口语化、带市井气，fellow 则语气中性、正式感稍强，美式英语中也常用。这里不比较 fellow 表示“伙伴的、同事的”这一定语用法（如 fellow students）。

All four name a person you work or spend time with. Associate: tied to work or business, formal. Companion: spending time together for comfort. Comrade: a friend bonded by struggle, often political. Fellow: informal, often British. Not compared: associate as verb, and fellow meaning man.

这四个词都可以指“一起共事或共处的人”，但语气和适用范围不同：associate 强调工作或生意上的关系，较为正式；companion 强调陪伴、共度时光，语气亲切，对象可以是人也可以是动物；comrade 强调共患难的情谊，常带政治或军事色彩；fellow 是非正式说法，常见于英式英语。这里不比较 associate 作动词表示“把……联系起来”的意思（如“associate the smell of coffee with early mornings”），也不比较 fellow 单独表示“男人”的用法。
