Breaking news: poor Spooner being ostracised (3-6)
I believe the answer is:
non-person
'ostracised' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'breaking news poor spooner' is the wordplay.
'breaking' indicates putting letters inside.
'news' becomes 'nn' (the abbreviation for 'new' written twice).
'poor' is an anagram indicator.
'spooner' with letters rearranged gives 'onperso'.
'nn' going around 'onperso' is 'NON-PERSON'.
'being' is the link.
Can you help me to learn more?
(Other definitions for non-person that I've seen before include "Celebrity now in obscurity" , "Way out" .)
