  help 是最日常、最通用的词，语气中性，口语和书面语中都极为常用，没有特别正式或紧急匮乏的含义。

  谢谢你上周末搬家时给予的帮助。

• assistance 本词

  A more formal word for help, typically offered by staff, services, or organizations rather than friends or family; common in official notices and polite requests.

• assist

  A formal or specialized noun, most often used in sports for a pass that helps a teammate score, or in technical phrases like assistive devices; rarely used for ordinary everyday help.

  assist 是较正式或专业化的名词，最常见于体育运动中指帮助队友得分的传球（助攻），或用于“辅助装置”等技术性短语中；日常生活中的普通帮助很少用这个词。

Help, assistance, aid, and assist all mean help for someone. Help is an everyday, neutral word. Assistance is formal, from staff or organizations. Aid means money or material help in charity situations. Assist is rare, a sports pass helping a teammate. Verb senses aren't compared.

这四个词在指“给予某人的帮助”这一名词义上意思相近，但正式程度和典型语境不同：help 最常用、最口语化，用于日常场合；assistance 更正式，多指机构、服务或组织提供的帮助；aid 多指物资或资金援助，常见于人道救援、慈善语境；assist 作名词较少见，多用于体育比赛中的“助攻”等专门场合。这里不比较 help、assist 作动词时“帮助”这一动词义。
