Sort of aura met by layman (7)
I believe the answer is:
amateur
'layman' is the definition.
(I've seen this before)
'sort of aura met by' is the wordplay.
'sort of' indicates anagramming the letters.
'by' is a charade indicator (letters next to each other).
'aura' put after 'met' is 'metaura'.
'metaura' anagrammed gives 'AMATEUR'.
(Other definitions for amateur that I've seen before include "he won't get paid" , "hobbyist" , "lacking professionalism" , "I'm no expert!" , "Inexpert" .)
