seme (n.)

"relating to significance or meaning," 1894, from French sémantique, applied by Michel Bréal (1883) to the psychology of language, from Greek sēmantikos "significant," from sēmainein "to show by sign, signify, point out, indicate by a sign," from sēma "sign, mark, token; omen, portent; constellation; grave" (Doric sama), from PIE root *dheie- "to see, look" (source also of Sanskrit dhyati "he meditates;" see zen).

The word has tended to become loose in application. Semanticize "invest (something) with meaning; analyze semantically" is by 1942.
