整齐 (zhěngqí) is an adjective meaning 'neat,' 'orderly,' or 'uniform.' It combines 整 (zhěng), which conveys completeness, tidiness, and organization, and 齐 (qí), meaning 'even,' 'aligned,' or 'in unison.' Together, they emphasize visual and structural harmony — things arranged without clutter, inconsistency, or disorder. The word often describes physical arrangements (e.g., books on a shelf, desks in a classroom) but also extends to abstract contexts like behavior, dress code, or data formatting.

It’s commonly used in daily life: teachers praise students for keeping their desks 整齐; office workers are reminded to keep files 整齐; and parents encourage children to fold clothes 整齐. Unlike some adjectives, 整齐 can function directly before nouns (e.g., 整齐的房间) or after 是/很 (e.g., 房间很整齐). It carries a neutral-to-positive connotation, implying care and discipline rather than rigidity.
