Unclean, soiled (5)
I believe the answer is:
dirty
I believe this is a double definition.
'unclean' is the first definition.
(I know that unclean can be written as dirty)
'soiled' is the second definition.
(I know that soiled can be written as dirty)
(Other definitions for dirty that I've seen before include "Not clean" , "Lewd" , "Mucky" , "Salacious" , "Soiled" .)
