False name employed in evident chicanery (8)
I believe the answer is:
invented
'false' is the definition.
(invented can mean false or fabricated)
'name employed in evident chicanery' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'employed in' is an insertion indicator.
'chicanery' indicates anagramming the letters (chicanery means deception or trickery).
'evident' with letters rearranged gives 'inveted'.
'n' going within 'inveted' is 'INVENTED'.
(Other definitions for invented that I've seen before include "Devised" , "Thought up, created" , "Originated" , "Creation, dreamt up" , "Made up" .)
