The French welcome a bad-tempered game (8)
I believe the answer is:
lacrosse
'game' is the definition.
(lacrosse is a kind of game)
'the french welcome a bad-tempered' is the wordplay.
'the french' becomes 'le'.
'welcome' indicates putting letters inside (in sense of 'inviting in').
'bad-tempered' becomes 'cross' ('cross' can be a synonym of 'bad-tempered').
'a'+'cross'='across'
'le' going around 'across' is 'LACROSSE'.
(Other definitions for lacrosse that I've seen before include "Like thirteen of the other clues in the French" , "Game played with netted sticks" , "Sport played with sticks" , "Ball game using netted stick" , "Score's uncertain after the Spanish" .)
