School is excellent, but beginning to go bad (4)
I believe the answer is:
high
I believe this is a quadruple definition!!
'school' is the first definition.
(high school is a kind of school)
'is excellent' is the second definition.
(high quality)
'but' is a link.
'beginning' is the third definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'to' is a link.
'go bad' is the fourth definition.
'high' can be an answer for 'bad' (both can describe rotten or decayed food). I am not sure about the 'go' bit.
Can you help me to learn more?
(Other definitions for high that I've seen before include "Oxford street - drunk" , "At altitude" , "Going off - in great spirits" , "Western film with Gary Cooper" , "Tall - loud - under the influence of drugs" .)
