Tailor almost never cut shroud (7)
I believe the answer is:
envelop
'shroud' is the definition.
(thesaurus)
'tailor almost never cut' is the wordplay.
'tailor' indicates an anagram (letters tailored or designed).
'almost' means to remove the last letter (most of the word but not all of it).
'cut' becomes 'lop' (lopping is a kind of cutting).
'never' with its final letter removed is 'neve'.
'neve' with letters rearranged gives 'enve'.
'enve'+'lop'='ENVELOP'
(Other definitions for envelop that I've seen before include "Wrap up - pen love (anag)" , "Compass" , "Enclose" , "Obscure" , "Surround and embrace" .)
