Sheepish utterance? (3)
I believe the answer is:
baa
'sheepish utterance?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for baa that I've seen before include "Sound from a ewe" , "Sound of a lamb" , "Lamb's cry" , "Bleat of a sheep" , "Sheep's bleat" .)
