Indian cloth I found under organ (5)
I believe the answer is:
lungi
'indian cloth' is the definition.
'lungi' can be an answer for 'cloth' (I've seen this before). I'm not sure about the 'indian' bit.
'i found under organ' is the wordplay.
'found under' means one lot of letters go next to another.
'organ' becomes 'lung' (lung is a kind of organ).
'i' after 'lung' is 'LUNGI'.
Can you help me to learn more?
(Other definitions for lungi that I've seen before include "Brightly coloured cloth worn in Asia as an ankle-length skirt" , "Burmese skirt" , "worn piece of cloth" , "Indian man's loin-cloth" , "Eastern dress" .)
