The word 整齐 is formed through a classic Chinese morphological process known as compounding, where two independent, synonymous characters are combined to create a single, reinforced concept. The first character, 整 (zhěng), carries meanings of "orderly", "whole", or "to put in order", while the second, 齐 (qí), means "even", "uniform", or "aligned". When paired, their semantic fields overlap and amplify each other, producing the composite meaning of "neat", "tidy", "orderly", or "uniform", which more precisely and vividly conveys the idea of both systematic arrangement and visual evenness than either character could alone. This formation exemplifies how many Chinese disyllabic words evolved for rhythmic and expressive clarity.
