Call on team for seats near arena (8)
I believe the answer is:
ringside
'seats near arena' is the definition.
'ringside' can be an answer for 'seats' (I have seen 'expensive seats' mean 'ringside' so perhaps 'seats' could also mean 'ringside'). I am unsure of the 'near arena' bit.
'call on team' is the wordplay.
'call' becomes 'ring' (telephone call).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'team' becomes 'side' (both can mean a sports team).
'ring'+'side'='RINGSIDE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for ringside that I've seen before include "seating area" , "Good seat here" , "Location of best seats at boxing match" , "Good position for witness" , "Location of best seats at boxing contest" .)
