City where there's no longer a tree to be found? (6)
I believe the answer is:
exeter
'city' is the definition.
(Exeter is an English city)
'there's no longer a tree to be found?' is the wordplay.
I cannot quite see how this works, but
an anagram of 'tree' is 'eter' which is within the answer.
'no longer' could be 'ex' (prefix meaning former or onetime) and 'ex' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'where' acts as a link.
Can you help me to learn more?
(Other definitions for exeter that I've seen before include "Administrative centre of Devon" , "County town and cathedral city of Devon" , "South-western English city" , "SW county town" , "See" .)
