- -hood suffix meaning "state or condition of being," from O.E. -had "condition, position," cognate with Ger. -heit, Du. -heid, all from P.Gmc. *haidus "manner, quality," lit. "bright appearance," from PIE (s)kai- "bright, shining." Originally a free-standing word (see HADE (Cf. hade)); in Modern English it survives only in this suffix.
