"miraculous communication of supernatural knowledge or power," 1660s, from Latin afflatus "a breathing upon, blast," figuratively "inspiration," noun use of past participle of afflare "to blow upon," from ad "to" (see ad-) + flare "to blow" (from PIE root *bhle- "to blow"). The literal meaning "a blowing or breathing upon" is rare in English, this sense being taken by afflation.
