Not at all wild wanderer (5)
I believe the answer is:
nomad
'wanderer' is the definition.
(I know that Nomad is a type of wanderer)
'not at all wild' is the wordplay.
'not at all' becomes 'no'.
'wild' becomes 'mad' (similar in meaning).
'no'+'mad'='NOMAD'
(Other definitions for nomad that I've seen before include "One travels from place to place with no permanent home" , "Roamer" , "A member of a wandering tribe" , "Member of travelling people" , "being domestically unstable" .)
