Run off to match in secret (5)

I believe the answer is:

elope

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

'run off' is the definition.
(I know that run off can be written as elope)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for elope that I've seen before include "leave with lover" , "Run away with lover" , "Run away secretly to marry" , "Run away to Gretna Green?" , "Run off with Mr/Ms Right" .)

I've seen this clue in The Globe and Mail.
