A limit I set for force in emergency (7)
I believe the answer is:
militia
'force in emergency' is the definition.
'militia' can be an answer for 'force' (I've seen this before). I am not sure about the 'in emergency' bit.
'a limit i set' is the wordplay.
'set' indicates anagramming the letters (instruction to set the letters).
'a'+'limit'+'i'='alimiti'
'alimiti' is an anagram of 'MILITIA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for militia that I've seen before include "Group of citizen soldiers" , "Body of citizen soldiers" , "Citizen soldiery" , "Armed body" , "Military force of trained civilians" .)
