I believe the answer is:

asset

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

'help' is the definition.
(an asset can be a help)

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

(Other definitions for asset that I've seen before include "One bringing benefit" , "Useful item" , "Anything of value" , "Valuable possession, worth having" , "Tessa (anag)" .)

I've seen this clue in The Telegraph.
