Perception subject to status (13)
I believe the answer is:
understanding
'perception' is the definition.
(I've seen this before)
'subject to status' is the wordplay.
'subject to' becomes 'under' (I've seen this before).
'status' becomes 'standing' (standing is a kind of status**).
'under'+'standing'='UNDERSTANDING'
(Other definitions for understanding that I've seen before include "Knowledge" , "Gathering" , "Getting" , "Discernment" , "Empathy" .)
