giddy

Etymology and origin of the English word giddy

Pronunciation

  • IPA: /ˈɡɪd.i/[1]

Etymology

It is inherited from Middle English gidi (“mad, foolish”),[2][3][4][5] inherited from Old English gidig, a variant of gydig “insane, possessed”,[2][3][6][4][5] probably from Proto-Germanic *gudigaz (“possessed by a god”), from the same root as god.[2][3][6][4][5]

Earliest recorded meaning

Mad, insane, foolish (about 1000).[7][3][6]

Semantic evolution

The word first meant possessed by a spirit, and so mad.[2][6] In Middle English it also meant foolish, unstable and dizzy.[2] The sense “elated, thoughtless” is from the 1540s,[6][7] and that of having a whirling sensation in the head from 1570.[7][6] The American Heritage Dictionary calls the modern sense “lighthearted, frivolous” the final secularization of a word once tied to possession by a god.[2]
