Arab that is bound to be a wanderer (7)
I believe the answer is:
bedouin
This clue could be a double definition.
'arab that is bound' is the first definition.
'Bedouin' can be an answer for 'arab' (Bedouin is an example). I am not sure about the remainder of the definition.
'a wanderer' is the second definition.
(Bedouin is an example)
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for bedouin that I've seen before include "Arab appears" , "Nomad of Jordan, for example" , "Desert wanderer" , "Member of a nomadic tribe of Arabs" , "Nomadic Arab of the desert" .)
