To higher level as purist possibly (8)
I believe the answer is:
upstairs
'to higher level' is the definition.
I can't tell whether this definition defines the answer.
'as purist possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'as'+'purist'='aspurist'
'aspurist' is an anagram of 'UPSTAIRS'.
Can you help me to learn more?
(Other definitions for upstairs that I've seen before include "On an upper floor" , "Away from servants" , "It's a spur (anag)" , "at the next level" , "See 3" .)
