Allowance of food for deserter with ten points (7)
I believe the answer is:
rations
'allowance of food for' is the definition.
'rations' can be an answer for 'allowance' (thesaurus). I'm unsure of the 'of food for' bit.
'deserter with ten points' is the wordplay.
'deserter' becomes 'rat' (both can mean a traitor).
'with' is a charade indicator (letters next to each other).
'ten' becomes 'IO' (IO resembles 10).
'points' becomes 'Ns' (two compass points).
'rat'+'io'+'ns'='RATIONS'
Can you help me to learn more?
(Other definitions for rations that I've seen before include "fixed allowance" , "Foodstuffs" , "Portions of food in time of scarcity" , "Commons" , "Limits (supplies)" .)
