Glaswegian companion leaving whisky? (4)
I believe the answer is:
scot
'glaswegian' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for scot that I've seen before include "someone with devolved parliament?" , "Someone from Dundee?" , "Eg, a Glaswegian" , "Tax, Glasgow native" , "Payment" .)
