recondite: [17] Recondite ‘obscure, abstruse’ means etymologically ‘hidden’. It comes from reconditus, the past participle of Latin recondere ‘hide’. This was a compound verb formed from the prefix re- ‘again’ and condere ‘put away, store’ (ultimate source of English condiment [15], literally ‘stored’ or ‘preserved’ food). => condiment[recondite etymology, recondite origin, 英语词源]
