The word 排除 is formed by combining two independent characters, each contributing a core meaning that merges into a new, unified concept. 排 carries the fundamental idea of "arranging in a row" or "pushing aside", while 除 carries the idea of "removing" or "eliminating". Their combination is not merely additive but synergistic, where the action of 排 (pushing aside) conceptually precedes and enables the action of 除 (removing), resulting in the comprehensive meaning of "to exclude, to eliminate, or to rule out" by systematically pushing something out of a set or a consideration.
