Drink and gossip endlessly (3)
I believe the answer is:
cha
'drink' is the definition.
(I've seen this before)
'gossip endlessly' is the wordplay.
'gossip' becomes 'chat' ('chat' can be a synonym of 'gossip').
'endlessly' means to remove the last letter.
'chat' with its last letter removed is 'CHA'.
'and' acts as a link.
(Other definitions for cha that I've seen before include "drink" , "Tea (colloq.)" , "Rosie Lee (slang)" , "Tea (colloquial)" , "not allowed in ski lodge" .)
