英文詞源

secret

secret: [14] Etymologically, something that is secret is ‘separated’ from others, hence put out of the way, hidden. The word comes via Old French secret from Latin sēcrētus, an adjectival use of the past participle of sēcernere ‘separate’. This was a compound verb formed from the prefix sē- ‘a(chǎn)part’ and cernere ‘separate’ (source also of English certain, discern, excrement, etc).

From the 16th to the 18th centuries, secret was used as a verb, meaning ‘hide’, but it was then altered to secrete, on the model of Latin sēcrētus. (The other verb secrete, ‘produce fluids or other substances’ [18], is a back-formation from secretion [17], which goes back to Latin sēcrētiō ‘separation’, a derivative of sēcernere.) A secretary is etymologically a ‘secret’ or confidential helper.
=> certain, decree, discern, excrement, secretary
