Feature, primarily pretence or reality? (4)
I believe the answer is:
fact
'reality?' is the definition.
(fact is a kind of reality)
'feature primarily pretence' is the wordplay.
'primarily' suggests taking the first letters.
'pretence' becomes 'act'.
The initial letter of 'feature' is 'f'.
'f'+'act'='FACT'
'or' acts as a link.
(Other definitions for fact that I've seen before include "Actuality" , "Fait accompli" , "matter of record" , "Indisputable thing" , "Datum" .)
