Sad university sportsperson (4)
I believe the answer is:
blue
This might be a double definition.
'sad university' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'sportsperson' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for blue that I've seen before include "See 7 Across" , "Vulgar" , "Colour; obscene" , "Colour - smutty" , "Varsity sportsman" .)
