Order as purist on another level? (8)
I believe the answer is:
upstairs
'on another level?' is the definition.
(I've seen this before)
'order as purist' is the wordplay.
'order' is an anagram indicator.
'as'+'purist'='aspurist'
'aspurist' with letters rearranged gives 'UPSTAIRS'.
(Other definitions for upstairs that I've seen before include "at the next level" , "In the top half of a house" , "See 3" , "Mentally (colloquial)" , "on another level" .)
