Worn out bagging large carp (5)
I believe the answer is:
bleat
'carp' is the definition.
(I've seen this before)
'worn out bagging large' is the wordplay.
'worn out' becomes 'be at' (I've seen this in another clue).
'bagging' is an insertion indicator (I've seen this in other clues).
'large' becomes 'L' (eg in clothes sizes).
'beat' going around 'l' is 'BLEAT'.
(Other definitions for bleat that I've seen before include "Whine" , "Sound from the fold" , "Cry of a lamb at table" , "Lamb's cry" , "kid makes such a noise" .)
