I believe the answer is:

spar

I'm a little stuck... Click here to teach me more about this clue!

This clue might be a double definition.

'box' is the first definition.
(sparring is a kind of boxing)

'of spares?' is the second definition.
The definition suggests a singular noun which matches the answer.

Can you help me to learn more?

(Other definitions for spar that I've seen before include "Practise boxing with a pole?" , "Stout pole to support rigging" , "Box - girder" , "Pole used in rigging - fight" , "dispute" .)
