• -head

    Origin 1

    From Middle English -hed, -hede, attested from the 12th century, continuing a hypothetical Old English *-hǣde ("-hood"), from Proto-Germanic *haidį̄ ("state, condition"), related to Proto-Germanic *haiduz ("manner, character, quality, state") (cognate with German -heit, Gothic 𐌷𐌰𐌹𐌳𐌿𐍃 (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 -hād), and finally to the wide replacement of -head by -hood even in adjectives.
