Live like a nomad (4)
I believe the answer is:
roam
'live like a nomad' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roam that I've seen before include "Wander freely" , "Wander widely" , "Peregrinate" , "Rove or ramble" , "'Wander, ramble (4)'" .)
