Real information on one taken in by a Parisian? (7)
I believe the answer is:
genuine
'real' is the definition.
(I know that real can be written as genuine)
'information on one taken in by a parisian?' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'on' says to put letters next to each other.
'one' becomes 'i' (Roman numeral).
'taken in by' is an insertion indicator.
'a parisian?' becomes 'une' ('a' in French).
'i' placed within 'une' is 'uine'.
'gen'+'uine'='GENUINE'
(Other definitions for genuine that I've seen before include "Not fake or counterfeit" , "'Real, unfeigned (7)'" , "Native" , "Bona fide, authentic" , "Ingenue - the real McCoy" .)
