Prophet sounds a bit boring (5)

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 remainder of the clue works.

(Other definitions for augur that I've seen before include "Portend, herald" , "Predict as from omens" , "forecast" , "Foretell from signs" , "Portend; Roman official" .)

I've seen this clue in The Globe and Mail.
