Renewed spirit regarding modern troops on time (11)
I believe the answer is:
refreshment
'renewed spirit' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'regarding modern troops on time' is the wordplay.
'regarding modern troops' becomes 'freshmen' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' is an insertion indicator.
'time' becomes 'ret' (I've seen this in other clues).
'freshmen' going within 'ret' is 'REFRESHMENT'.
Can you help me to learn more?
(Other definitions for refreshment that I've seen before include "Renewal, reinvigoration" , "stimulation" , "Food or drink" , "something to take down?" , "Light snack or drink" .)
