I believe the answer is:

eke

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

'supplement' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for eke that I've seen before include "long ago" , "Make a laborious living" , "Make last longer" , "Make a living laboriously - a palindrome" , "addition to Scots" .)

I've seen this clue in The Guardian.
