Hard to avoid in merciless villain’s garment? (5-7)
I believe the answer is:
habit-forming
'hard' is the definition.
(thesaurus)
'to avoid in merciless villain's garment?' is the wordplay.
I cannot really understand how this works, but
'to' could be 'for' and 'for' is found in the answer.
'in' is found in the answer.
'garment?' could be 'habit' (habiting is a kind of garmenting) and 'habit' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for habit-forming that I've seen is " Addictive".)
