Nourishment for new recruits (6)
I believe the answer is:
intake
'new recruits' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for intake that I've seen before include "Group of new students" , "Group of new pupils in a school" , "Place where gas or water enters" , "Number of acceptances as in school" , "Air inlet of jet engine" .)
