I believe the answer is:

intend

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

'mean' is the definition.
(to intend to something is to mean it)

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

(Other definitions for intend that I've seen before include "Have as purpose or in mind" , "Contemplate - mean - plan" , "1 dn [DESIGN]" , "Mean - purpose" , "Purport" .)

I've seen this clue in The Times.
