Provide entertainment and grub without support (5)
I believe the answer is:
cater
'provide entertainment' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for cater that I've seen before include "provide meals" , "so put out food?" , "Supply food for parties" , "React (anag.)" , "Trace (anag.)" .)
