Cry of sheep left in pound (5)
I believe the answer is:
bleat
'cry' is the definition.
(bleat is a kind of cry)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bleat that I've seen before include "Make complaint" , "Plaintive cry" , "Cry of a lamb at table" , "Sheep's weak cry" , "Say baa!" .)
