Etymology: "Shackly" is an adjective meaning loose, rickety or shaky, as of something that rattles or wobbles. It is probably formed from a dialectal verb "shackle", meaning to shake or rattle, with the common suffix "-y" added to turn the action into a quality. The verb is likely the source of the word, so the sense of something that trembles or rattles under strain carries straight through into the adjective.
