Intend to go in to hire some things to wear (7)
I believe the answer is:
raiment
'wear' is the definition.
(raiment is a kind of wear)
'intend to go in to hire' is the wordplay.
'intend' becomes 'aim' (aiming is a kind of intending).
'to go in' means one lot of letters goes inside another.
'to hire' becomes 'rent' ('rent' can be a synonym of 'hire').
'aim' placed within 'rent' is 'RAIMENT'.
'some things to' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for raiment that I've seen before include "Clothing (archaic)" , "Fancy clothes seen on minaret" , "Am inert (anag) - clothing" , "Old word for fine clothing" , "Clobber" .)
