I believe the answer is:

broaden

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

'expand' is the definition.
(broadening is a kind of expanding)

I can't explain the remainder of the clue.

(Other definitions for broaden that I've seen before include "In one direction, expand" , "Make more general" , "Make wide or liberal, perhaps the mind" , "Stretch" , "Make wider" .)

I've seen this clue in The Mirror.
