Dirty; ritually impure (7)
I believe the answer is:
unclean
This clue is a double definition.
'dirty' is the first definition.
(I know that dirty can be written as unclean)
'ritually impure' is the second definition.
(I've seen this before)
(Other definitions for unclean that I've seen before include "Polluted" , "Dirty; immoral" , "Ceremonially impure" , "Filthy" , "(Ritually) tainted" .)
