Wearing certain clothes to live (7)
I believe the answer is:
inhabit
'live' is the definition.
(I know that live can be written as inhabit)
'wearing certain clothes' is the wordplay.
'wearing' becomes 'in' (as in being 'in' certain clothes).
'certain clothes' becomes 'habit' (habit is a kind of clothes. I am not sure about the 'certain' bit.).
'in'+'habit'='INHABIT'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for inhabit that I've seen before include "people" , "Live in (a place)" , "Live in, occupy" , "Occupy (dwelling)" , "Dwell in" .)
