Universal train and air travel in the country one imagined (9)
I believe the answer is:
ruritania
'the country one imagined' is the definition.
I can't tell whether this definition defines the answer.
'universal train and air travel' is the wordplay.
'universal' becomes 'U' (film certificate).
'and' is a charade indicator (letters next to each other).
'travel' is an anagram indicator (I've seen 'travels' mean this).
'u'+'train'='utrain'
'utrain' put after 'air' is 'airutrain'.
'airutrain' with letters rearranged gives 'RURITANIA'.
'in' is the link.
Can you help me to learn more?
(Other definitions for ruritania that I've seen before include "Hope country" , "Anthony Hope's imagined central European kingdom" , "romantic situation" , "mythical land" , "adventurous setting" .)
