A relation, unaltered (2,2)
I believe the answer is:
as is
'unaltered' is the definition.
(I've seen this before)
'a relation' is the wordplay.
'relation' becomes 'sis' (sis is a kind of relation).
'a'+'sis'='AS IS'
(Other definitions for as is that I've seen before include "In existing state" , "In the current circumstances" , "without change" , "not changed" , "in the present circumstances" .)
