Where it comes from

The adjective is derived from Middle English gidi, gedy, gydy (“demonically controlled or possessed; crazy, insane; foolish, idiotic, ridiculous, unwise; unsure; (rare) dizzy, shaky; (rare) of an animal: crazed, out of control; a fool”) [and other forms], from Old English gidiġ, gydiġ (“possessed by a demon or spirit, insane, mad”), from Proto-West Germanic *gudīg (“ghostly, spirited”, literally “possessed by a god or spirit”), from *god (“god”) + *-ig, *-g (suffix forming adjectives with the senses of being, doing, or having). Thus the word's elements correspond to god + -y (suffix meaning ‘having the quality of’, forming adjectives).

The noun and the verb are derived from the adjective.
