Refuting news about some jewellery outside (9)
I believe the answer is:
answering
'refuting' is the definition.
(answering is a kind of refuting)
'news about some jewellery outside' is the wordplay.
'about' indicates anagramming the letters.
'some' becomes 'a'.
'jewellery outside' becomes 'ring' (I can't justify this - if you can you should believe this answer much more).
'news' mixed up with 'a' gives 'answe'.
'answe'+'ring'='ANSWERING'
Can you help me to learn more?
(Other definitions for answering that I've seen before include "Responding" , "Replying" , "Picking up receiver" , "Acknowledging" .)
