So old article offers comfort (6)
I believe the answer is:
soothe
'comfort' is the definition.
('soothe' can be a synonym of 'comfort')
'so old article' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'article' becomes 'the' (the 'definite article' part of speech).
'so'+'o'+'the'='SOOTHE'
'offers' is the link.
(Other definitions for soothe that I've seen before include "Calm down, placate" , "Console, pacify" , "Calm; relieve pain" , "to settle" , "'Console, comfort (6)'" .)
