Hardly a crazy wanderer (5)
I believe the answer is:
nomad
'wanderer' is the definition.
(I know that Nomad is a type of wanderer)
'hardly a crazy' is the wordplay.
'hardly' becomes 'no' (eg 'hardly a meal' means 'not a meal' or 'no meal').
'a crazy' becomes 'mad' (I've seen this before).
'no'+'mad'='NOMAD'
(Other definitions for nomad that I've seen before include "Itinerant" , "Member of travelling people" , "Traveller with no permanent home" , "is one unsettled?" , "One travels from place to place with no permanent home" .)
