The sign for the rough breathing is derived from H, which in the Old Attic alphabet (2 a) was used to denote h. Thus, HO ὁ the. After H was used to denote η, one half ([rough ]) was used for h (about 300 B.C.), and, later, the other half ([smooth]) for the smooth breathing. From [rough ] and [smooth] come the forms ‘and’.
