服务 (fú wù) is a noun meaning 'service' — the act of helping, assisting, or providing something useful to others, especially in professional, commercial, or social contexts. The character 服 means 'to serve' or 'to submit', and 务 means 'affair', 'task', or 'duty'; together, they convey the idea of performing duties for others’ benefit. It’s commonly used in phrases like 服务质量 (service quality), 顾客服务 (customer service), and 公共服务 (public service).

This word appears frequently in daily life — from restaurants and banks to government offices and online platforms. Unlike the verb 服务 (which can mean 'to serve' when used with appropriate grammar, e.g., 为…服务), the noun form typically functions as the subject or object of a sentence and often follows modifiers like 好、差、优质、周到, or precedes classifiers like 项 or 种. It carries a neutral-to-formal register and is rarely used in casual speech without modifiers.
