Loincloth with evidence of red-hot iron (5)
I believe the answer is:
dhoti
'loincloth' is the definition.
(dhoti is a kind of loincloth)
'of red-hot iron' is the wordplay.
'of' indicates the answer is hidden within the clue.
'DHOTI' is hidden within 'red hot iron'.
'with evidence' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for dhoti that I've seen before include "garment in India" , "Loin cloth" , "Cloth round middle" , "Simple Indian garment" , "Indian loincloth" .)
