Exhorting, encouraging (6)
I believe the answer is:
urging
I believe this clue is a double definition.
'exhorting' is the first definition.
('urge' can be a synonym of 'exhort')
'encouraging' is the second definition.
(urging is a kind of encouraging)
(Other definitions for urging that I've seen before include "Exhorting, goading" , "Impelling" , "Strongly encouraging" , "Strongly recommending" .)
