Wanderer, i.e. bound to wander! (7)
I believe the answer is:
bedouin
'wanderer' is the definition.
(Bedouin is an example)
'i e bound to wander' is the wordplay.
'to wander' indicates anagramming the letters.
'i'+'e'+'bound'='iebound'
'iebound' with letters rearranged gives 'BEDOUIN'.
(Other definitions for bedouin that I've seen before include "Member of a nomadic tribe of Arabs" , "Wandering Arab of the Sahara" , "travellers" , "Nomad of Jordan, for example" , "I dub one (anag)" .)
