Assessing one working in wartime restriction (9)
I believe the answer is:
rationing
'wartime restriction' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'assessing one working in' is the wordplay.
'assessing' becomes 'rating' (rating is a kind of assessing).
'one' becomes 'i' (Roman numeral).
'working' becomes 'on' (on can mean working or activated).
'in' indicates putting letters inside.
'i'+'on'='ion'
'rating' going around 'ion' is 'RATIONING'.
Can you help me to learn more?
(Other definitions for rationing that I've seen before include "process that should be fair for everybody" , "Limiting (a supply)" , "Wartime activity" , "Shortages lead to" .)
