The adjective is derived from Latin reconditus (“concealed, hidden; difficult to understand, unintelligible; shy, withdrawn”), participial adjective from the perfect passive participle of recondō (“to conceal, hide; to put away; to re-establish, put back”). Recondō is derived from re- + condō (“to conceal, hide; to put away, store; to put together; to build, establish; to fashion, form”) (ultimately from Proto-Indo-European dʰeh₁- (“to do, make; to place, put”)). The English word is cognate with Catalan recòndit (“hidden; private”), Italian recondito (“hidden, recondite”), Middle French recondit (“hidden; secret”), Portuguese recôndito (“hidden, secluded; isolated, remote”), Spanish recóndito (“hidden, recondite”). The noun was probably derived from the adjective by substantivization. The verb is also derived from the perfect passive participle of recondō; see the etymology section at -ate and above for more.
