Unavoidable fate of Tyneside canteen, I gathered (7)
I believe the answer is:
nemesis
'unavoidable fate' is the definition.
(Nemesis is the legendary spirit of retribution)
'tyneside canteen i gathered' is the wordplay.
'tyneside' becomes 'NE' (region in North East of England).
'canteen' becomes 'mess' (I've seen this before).
'gathered' means one lot of letters goes inside another.
'mess' enclosing 'i' is 'mesis'.
'ne'+'mesis'='NEMESIS'
'of' acts as a link.
(Other definitions for nemesis that I've seen before include "Nee Miss (anag.)" , "An agent of vengeance and retribution" , "Goddess of retribution in Greek mythology" , "causes downfall" , "Unbeatable rival" .)
