Word History

Etymology

Middle English, "knowledge, the ability to know, learning, branch of knowledge," borrowed from Anglo-French science, cience, borrowed from Latin scientia "knowledge, awareness, understanding, branch of knowledge, learning," noun derivative from scient-, sciens, present participle of sciō, scīre "to know," perhaps going back to Indo-European *skh₂-i(e/o)-, present tense formation from a verbal base *skeh₂-, *skh₂- "cut open, flay" (if sense development was "cut, incise, mark" > "distinguish" > "know"), whence also Sanskrit -chyati "(s/he) flays, pulls off (skin)" (verbal adjective chātaḥ, chitáḥ) and perhaps Greek scházō, scházein, also scháō, schân "to make an incision, open (a vein), let flow"

Note: Regarding earlier use of the words science and scientist see the reference to the article by Sydney Ross in the note at scientist. — Lexikon der indogermanischen Verben (2. Auflage, 2001) regards Latin sciō as a back-formation from nesciō, nescīre "to not know, be unfamiliar with," going back to *ne-skH-ii̯e-, a negative compound from the base of secō, secāre "to cut, sever, make an incision" (see saw entry 2), going back to *sekai̯e-, going back to *sekH-i̯e-. M. de Vaan (Etymological Dictionary of Latin and the Other Italic Languages, Brill, 2008), on the other hand, hypothesizes that sciō is formed with an athematic suffix from *skh₂-, so that as a present formation it is directly comparable with Sanskrit -chyati. The semantic progression producing a verb meaning "know" is in any case questionable, if, as the Indo-Iranian and Greek evidence suggests, the base *skeh₂-, *skh₂- means primarily "cut open, flay" (rather than "split, separate"). Ernout and Meillet (Dictionnaire étymologique de la langue latine) note that while this is the only plausible comparison for sciō, it is not at all certain ("Le rapprochement avec le groupe de 'couper' est en l'air, tout en étant, semble-t-il, le seul possible.")
