Scots city (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
glasgow
'scots city' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for glasgow that I've seen before include "Sauchiehall St. city" , "Scotland's largest city" , "Scots city" , "Scottish city on the Clyde" , "Scottish metropolis" .)
