Attested since the 1610s, from the earlier form trouzes (attested since the 1580s), extended from trouse (1570s), with plural ending typical of things in pairs, from Middle Irish triubhas (“close-fitting shorts”), of uncertain origin. The unexplained intrusive second -r- is perhaps due to the influence of drawers.
