Used to getting insured without safety first (6)
I believe the answer is:
inured
'used to' is the definition.
(thesaurus)
'getting insured without safety first' is the wordplay.
I cannot quite understand how this works, but
'getting' could be 're' (I've seen this in other clues) and 're' is located in the answer.
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for inured that I've seen before include "Accustomed to hardship" , "Hardened as by experience" , "used to it" , "Hardened, perhaps ruined" , "Hardened, maybe ruined" .)
