Denial incensed wanderer (5)
I believe the answer is:
nomad
'wanderer' is the definition.
(I know that Nomad is a type of wanderer)
'denial incensed' is the wordplay.
'denial' becomes 'no' (no is a kind of denial).
'incensed' becomes 'mad' (I've seen this in another clue).
'no'+'mad'='NOMAD'
(Other definitions for nomad that I've seen before include "Unsettled type" , "Member of a wandering pastoral community" , "One travels from place to place with no permanent home" , "Migrant" , "Wanderer" .)
