O.E. deaf "deaf, dull, obtuse," specialized from P.Gmc. *daubaz, from PIE dheubh-, which was used to form words meaning "confusion, stupefaction, dizziness" (cf. Gk. typhlos "blind). The word was pronounced to rhyme with reef until 18c. Deaf-mute is from 1837, after Fr. sourd-muet. Deaf-mutes were sought after in 18c.-19c. Britain as fortune-tellers. Deaf as an adder (O.E.) is from Psalms lviii.5.
