Possibly wide edition of the paper? (5)
I believe the answer is:
extra
This might be a double definition.
'possibly wide edition' is the first definition.
'extra' can be an answer for 'edition' (I have seen 'Special edition ' mean 'extra' so perhaps 'edition' could also mean 'extra'). I am not sure about the 'possibly wide' bit.
'the paper?' is the second definition.
(thesaurus)
'of' is the link.
Can you help me to learn more?
(Other definitions for extra that I've seen before include "Spare" , "Actor in non-speaking role" , "E.g. wide in cricket" , "additional supplies" , "Superfluous" .)
