I believe the answer is:

augur

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

'prophet' is the definition.
(augur is a kind of prophet)

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

(Other definitions for augur that I've seen before include "forecast" , "Prognosticate" , "Bode; soothsayer" , "Portend, be a sign of" , "Presage, foretell" .)

I've seen this clue in The Telegraph and The Times.
