Hollywood actor turns wanderer (5)
I believe the answer is:
nomad
'wanderer' is the definition.
(nomad is a kind of wanderer)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nomad that I've seen before include "Person wandering" , "Roamer" , "Member of travelling people" , "drifter" , "Wanderer" .)
