I believe the answer is:

border

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

'the frontier?' is the definition.
(I've seen this in another clue)

I don't understand the remainder of the clue.

(Other definitions for border that I've seen before include "Margin along the edge" , "Type of sheepdog" , "Bound" , "Frontier of a country" , "BLINK/BRINK" .)
