Cloth figure dog chewed during most of mass meeting (3,4)
I believe the answer is:
rag doll
'cloth figure' is the definition.
(doll made of cloth)
'dog chewed during most of mass meeting' is the wordplay.
'chewed' indicates an anagram.
'during' is an insertion indicator.
'most of' means to remove the last letter.
'mass meeting' becomes 'rally' (synonyms).
'dog' is an anagram of 'gdo'.
'rally' with its final letter taken away is 'rall'.
'gdo' going inside 'rall' is 'RAG-DOLL'.
(Other definitions for rag doll that I've seen before include "Toy made with scraps of cloth etc" , "soft toy" , "plaything's required" , "Page three girl" , "Long-haired cat" .)
