…citizen travellin’ in pick-up? (5)
I believe the answer is:
roman
'citizen' is the definition.
(I have seen 'European citizen' mean 'roman' so perhaps 'citizen' could also mean 'roman')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for roman that I've seen before include "Dominant political power of first centuries AD" , "Non-italic (type)" , "Plain upright type" , "Of an Italian city" , "eg Nero" .)
