Weird tree moss in Taunton district (8)
I believe the answer is:
somerset
'taunton district' is the definition.
The definition suggests a singular noun which matches the answer.
'weird tree moss' is the wordplay.
'weird' is an anagram indicator.
'tree'+'moss'='treemoss'
'treemoss' is an anagram of 'SOMERSET'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for somerset that I've seen before include "part of south-west England" , "Part of UK" , "SW county" , "Old English county" , "County of Wells, Taunton, Weston-super-Mare, etc." .)
