MacLean's editorial houses purged (8)
I believe the answer is:
cleansed
'purged' is the definition.
(thesaurus)
'maclean's editorial houses' is the wordplay.
'houses' says the answer is hidden in the clue (part of the clue houses the answer).
'CLEANSED' can be found hidden inside 'macleans editorial'.
(Other definitions for cleansed that I've seen before include "missing the filthy bits?" , "Leeds can (anag.)" , "Purified" , "Absolved" .)
