Dirty lace nun removed (7)
I believe the answer is:
unclean
'dirty' is the definition.
('unclean' can be a synonym of 'dirty')
'lace nun removed' is the wordplay.
'removed' is an anagram indicator (moved again).
'lace'+'nun'='lacenun'
'lacenun' with letters rearranged gives 'UNCLEAN'.
(Other definitions for unclean that I've seen before include "Polluted" , "Dirty, ritually impure" , "taboo" , "Filthy" , "Contaminated" .)
