Wander, rove (4)
I believe the answer is:
roam
I believe this clue is a double definition.
'wander' is the first definition.
(I know that wander can be written as roam)
'rove' is the second definition.
(I know that rove can be written as roam)
(Other definitions for roam that I've seen before include "Ramble without purpose" , "Wander about aimlessly" , "Wander widely" , "Travel widely" , "Stray" .)
