Country noble with an alteration (7)
I believe the answer is:
lebanon
'country' is the definition.
(Lebanon is an example)
'noble with an alteration' is the wordplay.
I cannot quite see how this works, but
'an' could be 'a' and 'a' is found in the answer.
an anagram of 'noble' is 'lebno' which is within the left over letters.
A single letter 'n' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lebanon that I've seen before include "Country associated with cedar trees" , "Country with cedars" , "Neighbour of Israel" , "Eastern Mediterranean country" , "E. Mediterranean nation" .)
