Foreign country controlled by uncouth leader excluded (10)
I believe the answer is:
outlandish
'foreign' is the definition.
(thesaurus)
'country controlled by uncouth leader excluded' is the wordplay.
I cannot really understand how this works, but
'country' could be 'land' (synonyms) and 'land' is present in the answer.
'excluded' could be 'out' (I've seen this before) and 'out' is found in the answer.
The remaining letters 'ish' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for outlandish that I've seen before include "Lad shoutin' (anag)" , "Bizarre - hound's tail (anag)" , "Exotic" .)
