Raiment ruined during building (7)
I believe the answer is:
minaret
'building' is the definition.
(I've seen this before)
'raiment ruined' is the wordplay.
'ruined' indicates anagramming the letters.
'raiment' is an anagram of 'MINARET'.
'during' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for minaret that I've seen before include "Slim tower of a mosque" , "Tower attached to mosque" , "Slender mosque tower" , "Mosque turret" , "Slender tower with balconies" .)
