Very old article, still (6)
I believe the answer is:
soothe
'still' is the definition.
(thesaurus)
'very old article' is the wordplay.
'very' becomes 'so' (both can mean 'extremely').
'old' becomes 'o' (abbreviation).
'article' becomes 'the' (the definite article in English).
'so'+'o'+'the'='SOOTHE'
(Other definitions for soothe that I've seen before include "Appease" , "Calm down, placate" , "Cause to feel better" , "Gently calm" , "Console, pacify" .)
