平常 (píng cháng) is an adjective meaning 'ordinary' or 'usual'—describing something that is typical, routine, or not special. The character 平 means 'level' or 'even', suggesting stability and lack of extremes; 常 means 'often' or 'constant', indicating frequency and regularity. Together, they convey the idea of what consistently occurs in daily life without deviation or emphasis.

This word is commonly used to describe habits, routines, appearances, or states that are unremarkable or expected—like a person’s usual behavior, standard weather, or everyday clothing. It often appears before nouns (e.g., 平常日子, 平常衣服) or after verbs like 是 or 感觉. While it can occasionally function adverbially (e.g., 他平常很早起床), its primary role is adjectival. It carries a neutral, slightly formal tone—not colloquial like 一般 but more natural than 正常 in routine contexts.
