Czechoslovakian city? (4)
I believe the answer is:
oslo
'city?' is the definition.
(Oslo is an example)
'czechoslovakian' is the wordplay.
'OSLO' is hidden within the letters.
However, I am uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for oslo that I've seen before include "where Ibsen lived under another name" , "European capital city (found in Czechoslovakia!)" , "Nordic capital" , "European capital in go-slow" , "European capital, known until 1924 as Christiania" .)
