Etymology
Derived from Latin complēmentum, from complēre ("to fill up"), combining com- (intensive prefix) + plēre ("to fill"). The morpheme ple retains its core meaning of "fill," while com- emphasizes completeness. Over time, the word evolved from literal "filling up" to abstract "completion" or "perfecting addition" in English.
