Make contribution to party? (5)
I believe the answer is:
cater
'make' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how one could define the other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for cater that I've seen before include "Provide what is needed or wanted" , "Provide goods or services for" , "Provide what is required" , "... you'll see minister" , "Supply provisions" .)
