Very passionate about loincloth one’s taken off (3-3)
I believe the answer is:
red-hot
'very passionate' is the definition.
(I've seen this before)
'about loincloth one's taken off' is the wordplay.
'about' becomes 're' (regarding).
'loincloth' becomes 'dhoti' (dhoti is a kind of loincloth).
'one' becomes 'i' (Roman numeral).
'taken off' indicates named letters should be taken away.
'dhoti' with 'i' taken away is 'dhot'.
're'+'dhot'='RED-HOT'
(Other definitions for red-hot that I've seen before include "Glowing; extremely popular" , "Of news, new and burning" , "Very good" , "(Of information) very recently received" , "Extremely passionate" .)
