giddy

giddy: [OE] Like enthusiastic, the etymological meaning of giddy is ‘possessed by a god’. Its distant ancestor was a prehistoric Germanic adjective *guthigaz, which was derived from *gutham ‘god’. This produced Old English gidig, which meant ‘insane’ or ‘stupid’. It was not until the 16th century that it acquired its main present-day meaning, ‘dizzy’.
=> god

giddy (adj.)

Old English gidig, variant of gydig "insane, mad, stupid," perhaps literally "possessed (by a spirit)," if it is from Proto-Germanic *gud-iga- "possessed by a god," from *gudam "god" (see god (n.)) + *-ig "possessed." Meaning "having a confused, swimming sensation" is from 1560s (compare sense evolution of dizzy). Meaning "elated" is from 1540s. Related: Giddily; giddiness.
