Sadly he gets none of the Neolithic circles (10)
I believe the answer is:
stonehenge
'of the neolithic circles' is the definition.
The definition suggests a singular noun which matches the answer.
'sadly he gets none' is the wordplay.
'sadly' is an anagram indicator.
'he'+'gets'+'none'='hegetsnone'
'hegetsnone' is an anagram of 'STONEHENGE'.
Can you help me to learn more?
(Other definitions for stonehenge that I've seen before include "[WILTS] monument" , "Wiltshire landmark" , "prehistoric pillars" , "Wiltshire prehistoric monument" , "heritage site" .)
