From Old English 'hīehþo' (highness), the abstract noun of 'high.'
The measurement from base to top.
From Old English 'hīehþo' (highness, height), from Proto-Germanic *hauhiþō, from *hauhaz (high). Simply the abstract noun of 'high.' Key roots: *hauhaz (Proto-Germanic: "high").
Despite containing '-ght,' 'height' does NOT rhyme with 'weight' — its pronunciation preserves the original long 'i' from 'high.'
