One without a permanent address (5)
I believe the answer is:
nomad
'one without a permanent address' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nomad that I've seen before include "Member of travelling people" , "One keeps moving" , "Unsettled type" , "A wandering tribesman" , "Traveller with no permanent home" .)
