Lay out, as lucre (7)
I believe the answer is:
secular
'lay' is the definition.
(I know that lay can be written as secular)
'out as lucre' is the wordplay.
'out' is an anagram indicator.
'as'+'lucre'='aslucre'
'aslucre' anagrammed gives 'SECULAR'.
(Other definitions for secular that I've seen before include "Worldly" , "Not spiritual" , "Layman's" , "Lay" , "Profane" .)
