I believe the answer is:

manana

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

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

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

(Other definitions for manana that I've seen before include "Sharply-defined" , "Tomorrow for Pedro" , "Tomorrow - at an unspecified point in the future (Spanish)" , "Tomorrow (suggesting procrastination)" , "It's tomorrow, senor" .)

I've seen this clue in The Telegraph.
