Urged on new experience (7)
I believe the answer is:
undergo
'experience' is the definition.
(I know that experience is a more specific form of the action the undergo)
'urged on new' is the wordplay.
'new' indicates anagramming the letters.
'urged'+'on'='urgedon'
'urgedon' anagrammed gives 'UNDERGO'.
(Other definitions for undergo that I've seen before include "Endure, experience something" , "put up with" , "Endure for guerdon" , "Experience or live through" , "Stand" .)
