Old English brēc (plural of brōc, of Germanic origin; related to Dutch broek), interpreted as a singular form. The original sense was 'garment covering the loins and thighs' (compare with breeches), hence 'the buttocks' (sense 2 of the noun, mid 16th century), later 'the hind part' of anything (late 16th century).
