Finally, channel dealing with English sport (8)
I believe the answer is:
lacrosse
'sport' is the definition.
(lacrosse is a kind of sport)
'finally channel dealing with english' is the wordplay.
'finally' says to take the final letters.
'dealing with' becomes 'across' (I can't explain this - if you can you should believe this answer much more).
'english' becomes 'E' (abbreviation).
The last letter of 'channel' is 'l'.
'l'+'across'+'e'='LACROSSE'
Can you help me to learn more?
(Other definitions for lacrosse that I've seen before include "Game played with nets on sticks" , "Ball game using netted stick" , "Game played with a netted stick" , "Score's uncertain after the Spanish" , "Like thirteen of the other clues in the French" .)
