A Parisian who places tips (11)
I believe the answer is:
'tips' is the definition.
(I've seen this in another clue)
'a parisian who places' is the wordplay.
'a' becomes 'per' (eg 'one a day' means 'one per day').
'parisian who' becomes 'qui' ('who' in French).
'places' becomes 'sites' (a site is a place or location).
(Another definition for perquisites that I've seen is " tips?".)
