Haggled about having put on weight at the pub (9)
I believe the answer is:
bargained
'haggled about' is the definition.
'bargained' can be an answer for 'haggled' (I've seen this before). I am not certain of the 'about' bit.
'put on weight at the pub' is the wordplay.
'put on weight' becomes 'gained' (I've seen this in another clue).
'at' says to put letters next to each other (I've seen this in other clues).
'the pub' becomes 'bar' (both are drinking establishments).
'gained' put after 'bar' is 'BARGAINED'.
'having' acts as a link.
Can you help me to learn more?
(Other definitions for bargained that I've seen before include "haggled" , "Negotiated" .)
