Enthusiastic about, maybe, Geordie’s chants (7)
I believe the answer is:
intones
'chants' is the definition.
('intone' can be a synonym of 'chant')
'enthusiastic about maybe geordie's' is the wordplay.
'enthusiastic about' becomes 'into' (into can mean interested in or enthusiastic about).
'maybe geordie's' becomes 'NE's' (Geordies are from Tyneside in the North East).
'into'+'nes'='INTONES'
(Other definitions for intones that I've seen before include "Recites in a chanting voice" , "Chants" .)
