Extend a banquet (6)
I believe the answer is:
spread
I believe this clue is a double definition.
'extend' is the first definition.
(I know that spread is a more specific form of the action extend)
'a banquet' is the second definition.
(I know that banquet can be written as spread)
(Other definitions for spread that I've seen before include "Scatter - padres (anag)" , "Stretch out; large meal" , "Disseminate through padres" , "advance" , "Unfold - scatter" .)
