Provide sustenance from contents of coffee dispenser (4)

Ross

I believe the answer is:

feed

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

'provide sustenance' is the definition.
'feed' can be an answer for 'provide' (feeding is a kind of providing). I'm not sure about the 'sustenance' bit.

'contents of coffee dispenser' is the wordplay.
'contents of' indicates the answer is hidden within the clue.
'FEED' is hidden in the letters of 'coffee dispenser'.

'from' is the link.

Can you help me to learn more?

(Other definitions for feed that I've seen before include "Given payment" , "Fodder" , "Give (or take) nourishment" , "Nourish" , "comedian's assistant" .)
