Expected pounds for fight (4)
I believe the answer is:
duel
'fight' is the definition.
(duel is a kind of fight)
'expected pounds' is the wordplay.
'expected' becomes 'due' (similar in meaning).
'pounds' becomes 'l' (L can represent the monetary pound).
'due'+'l'='DUEL'
'for' acts as a link.
(Other definitions for duel that I've seen before include "Affaire d'honneur" , "Two-person combat" , "Fight between two persons" , "Arranged fight" , "shoot-out?" .)
