Reference standard article about person from ... (6)
I believe the answer is:
norman
'person from' is the definition.
I can't judge whether this definition defines the answer.
'reference standard article' is the wordplay.
'reference standard' becomes 'norm' (norm can mean what is standard).
'article' becomes 'an' (indefinite article).
'norm'+'an'='NORMAN'
'about' acts as a link.
(Other definitions for norman that I've seen before include "Someone who's not British" , "15 [JANE] the clothing company" , "Old invader" , "he invaded England" , "Old French r" .)
