Whole game in a day seen by a Parisian (10)
I believe the answer is:
unabridged
'whole' is the definition.
'game in a day seen by a parisian' is the wordplay.
'game' becomes 'bridge' (bridge is a kind of game**).
'in' indicates putting letters inside.
'day' becomes 'd'.
'seen by' is a charade indicator (letters next to each other).
'a parisian' becomes 'un'.
'a'+'d'='ad'
'bridge' put within 'ad' is 'abridged'.
'abridged' after 'un' is 'UNABRIDGED'.
(Other definitions for unabridged that I've seen before include "Complete" , "published in full" , "Not shortened" .)
