- A variant of -hood.
From Middle English -hede, -hed, attested from the 12th century, continuing a hypothetical Old English *-haedu, cognate to German -heit, from a Common Germanic suffix of condition or quality, *-haidu-z (Gothic -haidus). Originally restricted to adjectives, the suffix began to be attached to nouns as well from at least the 15th century, leading to confusion with the -hood suffix (Old English -hád), and finally to the wide replacement of -head by -hood even in adjectives.
