tryst

Etymology

From Middle English tryst, trist, from Old French triste, tristre (“waiting place, appointed station in hunting”), probably from a North Germanic source such as Old Norse treysta (“to make safe, secure”), from traust (“confidence, trust, security, help, shelter, safe abode”), from Proto-Germanic *traustą (“trust, shelter”), from Proto-Indo-European *deru-, *dreu-, *drū- (“to be firm, be solid”). Doublet of trust (which see).
