Etymology

The word "dissemble" originates from the Latin dissimulare (to disguise or conceal), which evolved into Old French dessembler (to be different). The English form combines the prefix dis- (indicating reversal or negation) with semble (from Latin simulare, meaning "to appear or imitate"). The morpheme semble is also seen in "assemble" (to gather together) and "resemble" (to look like). Over time, "dissemble" narrowed to specifically mean hiding truth through deception, reflecting its Latin roots in concealment.
