Bound to carry the can for racing (9)
I believe the answer is:
sprinting
'racing' is the definition.
The answer and definition can be both to do with motion as well as being present participle verbs.
Maybe there's an association between them I don't understand?
'bound to carry the can' is the wordplay.
'bound' becomes 'spring' (both can mean to leap).
'to carry' means one lot of letters goes inside another.
'the can' becomes 'tin' (both are metal containers).
'spring' going around 'tin' is 'SPRINTING'.
'for' acts as a link.
Can you help me to learn more?
(Another definition for sprinting that I've seen is " running quickly".)
