غَنَّاءٌ
A singer; (MA;) [as also
مُغَنٍّ; and مُغَنِّيَةٌ
a female singer, a songstress:] according to Ibn-Ya'eesh, a
مُغَنٍّ is thus called لِأَنَّهُ يُغَنِّنُ
صَوْتَهُ, i. e. because he makes his voice to have in it a غُنَّة [or sort of nasal sound, or twang]; the word being, in his opinion, originally, مُغَنِّنٌ, with three ن, the last of which is changed into ى, when one says المُغَنِّى, for the purpose of alleviating the utterance.

النُّونِ.)
