easily persuaded (8)
I believe the answer is:
biddable
'easily persuaded' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for biddable that I've seen before include "Meekly ready to follow instructions" , "Ready to be instructed" , "Willing to obey" , "Willing to be instructed" , "Obedient" .)
