Those who fight will only get very small slices of toast (8)
I believe the answer is:
soldiers
'toast' is the definition.
(I know that Soldiers is a type of toast)
'those who fight will only get very small slices' is the wordplay.
I cannot really understand how this works, but
'very' could be 'so' (both can mean 'extremely') and 'so' is present in the answer.
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for soldiers that I've seen before include "Strips of toast for egg dipping" , "More than one fighter" , "Military personnel" , "Troopers" , "men" .)
