I believe the answer is:

cater

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for cater that I've seen before include "... you'll see minister" , "Supply food and drink" , "Trace in order to serve" , "Provide food and drink (for an event)" , "Supply food for parties" .)

I've seen this clue in The Hindu.
