The Parisian boy gets a bit of instruction (6)
I believe the answer is:
lesson
'a bit of instruction' is the definition.
('lesson' is part of 'instruction')
'the parisian boy' is the wordplay.
'the parisian' becomes 'les' (definite article in French).
'boy' becomes 'son' (synonyms).
'les'+'son'='LESSON'
'gets' acts as a link.
(Other definitions for lesson that I've seen before include "Single period of instruction" , "Sermon or teaching session" , "A session in school or an example" , "Severe reproof" , "Moral" .)
