Hardly crazy wanderer (5)
I believe the answer is:
nomad
'wanderer' is the definition.
(I know that Nomad is a type of wanderer)
'hardly crazy' is the wordplay.
'hardly' becomes 'no' (eg 'hardly a meal' means 'not a meal' or 'no meal').
'crazy' becomes 'mad' (synonyms).
'no'+'mad'='NOMAD'
(Other definitions for nomad that I've seen before include "drifter" , "Rover" , "Roving person" , "A wandering tribesman" , "one of those with no fixed home" .)
