Paddy has so much French spirit (7)
I believe the answer is:
tantrum
'paddy' is the definition.
(I've seen this before)
'so much french spirit' is the wordplay.
'so much french' becomes 'tant' ('so much' in French).
'spirit' becomes 'rum' (alcoholic spirit).
'tant'+'rum'='TANTRUM'
'has' acts as a link.
(Other definitions for tantrum that I've seen before include "Paddy" , "Hissy fit" , "Childish outbreak of temper" , "Uncontrolled outburst of anger" , "Display of bad temper" .)
