European city with Scot going on the tube (7)
I believe the answer is:
latvian
'european' is the definition.
(someone from Latvia)
'city with scot going on the tube' is the wordplay.
'city' becomes 'LA' (Los Angeles).
'with' is a charade indicator (letters next to each other).
'scot' becomes 'ian' (Scottish given name).
'going on' means one lot of letters go next to another.
'the tube' becomes 'tv' (I can't explain this - if you can you should believe this answer much more).
'ian' after 'tv' is 'tvian'.
'la' put next to 'tvian' is 'LATVIAN'.
Can you help me to learn more?
(Other definitions for latvian that I've seen before include "republican" , "who lives in ex-Communist country?" , "of a recently liberated state" , "Baltic national" , "Baltic language" .)
