semantic (adj.)
1894, from French sémantique, applied by Michel Bréal (1883) to the psychology of language, from Greek semantikos "significant," from semainein "to show by sign, signify, point out, indicate by a sign," from sema "sign, mark, token; omen, portent; constellation; grave" (Doric sama), from PIE root *dheie- "to see, look" (cognates: Sanskrit dhyati "he meditates;" see zen).
