hump: [18] Hump seems to have originated among the Low German dialects of North Germany and the Low Countries – Dutch, for instance, has the probably related homp ‘lump’. It first appeared in English towards the end of the 17th century in the compound hump-backed, but by the first decade of the 18th century it was being used on its own. (Another theory is that it arose from a blend of the now obsolete crumpbacked with hunchbacked [16], whose hunch- is of unknown origin.)
