Aching terribly to restrict women's gossip (7)
I believe the answer is:
chinwag
'gossip' is the definition.
(I've seen this before)
'aching terribly to restrict women's' is the wordplay.
'terribly' indicates anagramming the letters.
'to restrict' means one lot of letters goes inside another.
'women' becomes 'w'.
'aching' with letters rearranged gives 'chinag'.
'chinag' placed around 'w' is 'CHINWAG'.
(Other definitions for chinwag that I've seen before include "Yak" , "Chat (slang)" , "Can Whig have an informal chat?" , "Informal conversation" , "Gossip" .)
