unwieldy[14]  Unwieldy originally meant‘weak, feeble’ (‘a toothless, old, impotent, and unwieldy woman’, Reginald Scot, Discovery of Witch-craft 1584). The meaning ‘awkward to handle’ developed in the 16th century. The word was based on the now seldom encountered wieldy, which evolved from Old English wielde‘active, vigorous’. This in turn went back to the Germanic base *walth- ‘have power’, source
also of English herald and wield.
