Muse with a lyre (5)
I believe the answer is:
erato
'muse with a lyre' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for erato that I've seen before include "Who may have inspired poetry" , "inspiration for poetry" , "Muse of lyric poetry and mime" , "Inspiring female" , "poetic patroness" .)
