Team weakens, stuffed with southern hotel's extra food (4,6)
I believe the answer is:
side dishes
'extra food' is the definition.
(dishes added to a meal)
'team weakens stuffed with southern hotel's' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'weakens' becomes 'dies'.
'stuffed with' means one lot of letters goes inside another (some letters get stuffed inside).
'southern hotel's' becomes 'sh' (this might be a standard abbreviation I've not previously seen).
'dies' enclosing 'sh' is 'dishes'.
'side'+'dishes'='SIDE-DISHES'
Can you help me to learn more?
(Other definitions for side dishes that I've seen before include "Accompaniments to main course" , "Extra portions" .)
