Look at article and fume (6)
I believe the answer is:
seethe
'fume' is the definition.
(I know that fume can be written as seethe)
'look at article' is the wordplay.
'look at' becomes 'see' (I've seen this in another clue).
'article' becomes 'the' (the definite article).
'see'+'the'='SEETHE'
'and' acts as a link.
(Other definitions for seethe that I've seen before include "Be furious" , "Boil; be intensely angry" , "Barely contain one's anger" , "get very angry" , "Smoulder" .)
