I believe the answer is:

lucifer

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

'match?' is the definition.
(I know that match can be written as lucifer)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for lucifer that I've seen before include "the adversary" , "Devil - match!" , "from the abyss?" , "Satan, Son of the Morning" , "flares up when struck" .)

I've seen this clue in the Evening Standard.
