From which the spectators watch splendid resistance (10)
I believe the answer is:
grandstand
'from which the spectators watch' is the definition.
I can't judge whether this definition defines the answer.
'splendid resistance' is the wordplay.
'splendid' becomes 'grand' (both can mean impressive).
'resistance' becomes 'stand' (I've seen this before).
'grand'+'stand'='GRANDSTAND'
Can you help me to learn more?
(Other definitions for grandstand that I've seen before include "Main structure for watching sporting events" , "Show off in America" , "Main area for race spectators" , "From which spectators watch" , "Racecourse building" .)
