Boxer taking in r-row leading to afters? (7)
I believe the answer is:
pudding
'afters?' is the definition.
(both can refer to the sweet course of a meal)
'boxer taking in r-row' is the wordplay.
'boxer' becomes 'pug' (I've seen this before**).
'taking in' indicates putting letters inside.
'r-row' becomes 'ddin' ('din' said with a stammer like 'row' was; both can mean a loud disturbance).
'pug' placed around 'ddin' is 'PUDDING'.
'leading to' acts as a link.
(Other definitions for pudding that I've seen before include "Sweet course" , "One course" , "Chubby person" , "Pease - -" , "Cooked sweet dish" .)
