Be peripatetic (4)
I believe the answer is:
rove
'be peripatetic' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rove that I've seen before include "Ramble, roam, wander" , "Wander aimlessly" , "Range" , "Roam about aimlessly" , "Don't stay in one place" .)
