All there in Glasgow for traveller? (5)
I believe the answer is:
nomad
'for traveller?' is the definition.
(nomad is a kind of traveller)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nomad that I've seen before include "Unsettled type" , "Roving person" , "is one unsettled?" , "Member of a wandering pastoral community" , "Rover" .)
