Selected source glosses provide context, not a complete modern definition inventory

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.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
