What a swaddy has to eat at the canteen (3)
I believe the answer is:
wad
'eat at the canteen' is the definition.
I can't tell whether this defines the answer.
'what a swaddy has' is the wordplay.
'has' indicates a hidden word.
'WAD' is hidden within 'what swaddy'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for wad that I've seen before include "Pad of loose material used for packing" , "Compact mass" , "Bankroll; sandwich (slang)" , "A thick bundle, maybe of money" , "A bundle as of documents or banknotes" .)
