Person creating buzz over article (5)
I believe the answer is:
human
'person' is the definition.
('human' can be a synonym of 'person')
'buzz over article' is the wordplay.
'buzz' becomes 'hum' ('hum' can be a synonym of 'buzz').
'over' is a charade indicator (letters next to each other).
'article' becomes 'an' (indefinite article).
'hum'+'an'='HUMAN'
'creating' acts as a link.
(Other definitions for human that I've seen before include "Mortal; compassionate" , "Anthropoid" , "Not divine, animal or mechanical" , "Genial, kind" , "Fallible - person" .)
