Advise caution? (6)

I believe the answer is:

exhort

This clue is a double definition.

'advise' is the first definition.
(I know that exhort is a more specific form of advise)

'caution?' is the second definition.
(thesaurus)

(Other definitions for exhort that I've seen before include "Encourage, urge" , "Urge, counsel earnestly" , "Spur on" , "Call" , "Entreat earnestly, urge" .)

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