Wells found here supply tree moss (8)
I believe the answer is:
somerset
'wells found here' is the definition.
The definition suggests a singular noun which matches the answer.
'supply tree moss' is the wordplay.
'supply' indicates an anagram (in a supple way).
'tree'+'moss'='treemoss'
'treemoss' anagrammed gives 'SOMERSET'.
Can you help me to learn more?
(Other definitions for somerset that I've seen before include "English county known for its cider and Cheddar cheese" , "English county in the West Country" , "Southern English county" , "... and another" , "leap, occasionally" .)
