Number furious to see traveller (5)
I believe the answer is:
nomad
'traveller' is the definition.
(nomad is a kind of traveller)
'number furious' is the wordplay.
'number' becomes 'no' (abbreviation for 'number').
'furious' becomes 'mad' (I've seen this in other clues).
'no'+'mad'='NOMAD'
'to see' is the link.
(Other definitions for nomad that I've seen before include "Roving person" , "Person of no fixed abode" , "A wandering tribesman" , "Person wandering" , "Damon (anag.)" .)
