Tear I am to mend in the clothing (7)
I believe the answer is:
raiment
'the clothing' is the definition.
(raiment is a kind of clothing)
'tear i am to mend in' is the wordplay.
'tear' becomes 'rent' (rent is a kind of tear).
'to mend' is an anagram indicator (I've seen 'mended' mean this).
'in' indicates putting letters inside.
'i'+'am'='iam'
'iam' with letters rearranged gives 'aim'.
'rent' placed around 'aim' is 'RAIMENT'.
(Other definitions for raiment that I've seen before include "Poetic word for clothing" , "Clothing (poetically)" , "clothing for poets" , "Something put on" , "Minaret (anag) - clothing" .)
