Drive right around brook (5)
I believe the answer is:
river
'brook' is the definition.
(thesaurus)
'drive right around' is the wordplay.
'around' indicates a hidden word.
'RIVER' is hidden within 'drive right'.
(Other definitions for river that I've seen before include "Such as the Nile or Amazon" , "Flowing water" , "Thames is one" , "x or y, so to speak" , "Waterway" .)
