When aboard taxi, half of English county's a more exotic place (10)
I believe the answer is:
casablanca
'more exotic place' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'when aboard taxi half of english county's a' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'aboard' means one lot of letters goes inside another.
'taxi' becomes 'cab' (synonyms).
'half of english county's' becomes 'lanc' (I can't justify this - if you can you should believe this answer much more).
'as' inserted into 'cab' is 'casab'.
'casab'+'lanc'+'a'='CASABLANCA'
Can you help me to learn more?
(Other definitions for casablanca that I've seen before include "City and port of Morocco" , "Moroccan city; film" , "romantic movie" , "Famous Bogart film" , "1942 film starring Bogart and Bergman" .)
