Cry of a little old lady possessing nothing (5)
I believe the answer is:
groan
'cry of a little' is the definition.
'groan' can be an answer for 'cry' (thesaurus). I'm not sure about the 'of a little' bit.
'old lady possessing nothing' is the wordplay.
'old lady' becomes 'gran' (I've seen this before).
'possessing' is an insertion indicator.
'nothing' becomes 'O' (looks like zero - 0).
'gran' going around 'o' is 'GROAN'.
Can you help me to learn more?
(Other definitions for groan that I've seen before include "express disapproval" , "painful sigh" , "Expression of pain or disapproval" , "Sound of pain or disapproval" , "Sound of pain or despair" .)
