Etymology Origin:
Derived from Latin incisus (past participle of incidere "to cut into"), the word evolved to metaphorically describe mental sharpness. The root cis appears in related words like "scissors" (cutting tool) and "decision" (cutting off alternatives). The suffix -ive transforms the action into a quality, giving "incisive" its modern sense of penetrating clarity.
