Frequently, to a bard (3)
I believe the answer is:
oft
'frequently to a bard' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oft that I've seen before include "Old song'... in the stilly night'" , "(In poetry) frequently" , "Frequently in archaic term" , "Many times, of old" , "Many times, to the poet" .)
