Etymology tree Proto-Indo-European *kewk- Proto-Indo-European *kówk-o-s Proto-Germanic *hauhaz Proto-Indo-European *-teh₂der. Proto-Germanic *-iþō Proto-Germanic *hauhiþō Proto-West Germanic *hauhiþu Old English hīehþu Middle English heighte English height From Middle English heighte, heiȝþe, from Old English hēahþu, hēhþo, hīehþu (“height”), Proto-West Germanic hauhiþu, from Proto-Germanic hauhiþō (compare *hauhaz). Equivalent to high + -t (abstract nominal suffix). The regular pronunciation is now obsolete /heɪt/ (as with other words in -eight); the modern form developed early on, at first as a variant, by analogy with the underlying adjective.
