Attack inhibits left over race (6)
I believe the answer is:
slalom
'race' is the definition.
('slalom' means to move in a zigzag)
'attack inhibits left over' is the wordplay.
I cannot quite understand how this works, but
'left' could be 'al' (I've seen this in other clues) and 'al' is found in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for slalom that I've seen before include "Downhill skiing race" , "Downhill ski-race over a winding course" , "Ski race down zig-zag course" , "Ski racing event" , "Winter Olympic event" .)
