My amusing upset in the sports centre (9)
I believe the answer is:
gymnasium
'the sports centre' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'my amusing upset' is the wordplay.
'upset' indicates anagramming the letters.
'my'+'amusing'='myamusing'
'myamusing' anagrammed gives 'GYMNASIUM'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for gymnasium that I've seen before include "Place for exercising" , "... German school" , "Keep-fit facility" , "Place to work out" , "Physical training facility" .)
