Natter about including new beginner (7)
I believe the answer is:
entrant
'beginner' is the definition.
(entrant is a kind of beginner)
'natter about including new' is the wordplay.
'about' is an anagram indicator.
'including' is an insertion indicator.
'new' becomes 'n'.
'natter' anagrammed gives 'entrat'.
'entrat' placed around 'n' is 'ENTRANT'.
(Other definitions for entrant that I've seen before include "Participant in competition" , "Competitor, contestant" , "New member or competitor" , "Who goes in" , "One going in for a race or competition" .)
