Some article — extremely newsy! (3)
I believe the answer is:
any
'some' is the definition.
(similar in meaning)
'article extremely newsy' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'extremely' suggests removing the centre (only the extremes of the word are used).
'newsy' with its centre taken out is 'ny'.
'a'+'ny'='ANY'
(Other definitions for any that I've seen before include "One, no matter which" , "'Whatever'" , "One, some, every or all without specification" , "One or some, whichever you choose" , "One (unspecified)" .)
