Space entertaining Nero, primarily? (5)
I believe the answer is:
arena
'space entertaining nero primarily?' is the definition.
I can't judge whether this defines the answer.
'space entertaining nero primarily?' is the wordplay.
'space' becomes 'area' (I've seen this in another clue).
'entertaining' is an insertion indicator.
'primarily?' says to take the initial letters (I've seen 'primarily' mean this).
The initial letter of 'nero' is 'n'.
'area' enclosing 'n' is 'ARENA'.
Can you help me to learn more?
(Other definitions for arena that I've seen before include "Wembley, for example" , "... might perform here" , "Show ring" , "Ring for contest" , "Area of endeavour" .)
