Word History

Etymology

borrowed from Greek sēmantikós "(of sounds) conveying meaning, significant, (of a circumstance) indicative," from sēmantós, verbal adjective of sēmaínein "to indicate, point out, signify, make a signal, give a sign, (in middle voice) mark, identify" (verbal derivative from the base of sēmat-, sêma "distinguishing mark, sign, token, signal, omen, tomb" and sēmeîon "marking, sign, token, signal") + -ikos -ic entry 1; sēm- in sêma and sēmeîon of uncertain origin

Note: The base sēm-, Doric sām- has been compared with Sanskrit dhyāma "thought" (attested only in lexica) and dhyā́yati "s/he thinks, contemplates." Greek sêma would then be the outcome of Indo-European *d^hi̯eh₂-mn̥-. The meanings "sign" and "thought" are too far apart, however, to support such an etymology. The derivative sēmeîon is peculiar in that -mat- is a suffix and would not ordinarily be split apart in order to add another suffix. A comparable formation is mnêma "reminder, record, memorial" and the near-synonymous mnēmeîon, though in this case the ulterior etymology is clear.
