Joint league champions? (7)
I believe the answer is:
topside
This could be a double definition.
'joint' is the first definition.
(joint of beef)
'league champions?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
Can you help me to learn more?
(Other definitions for topside that I've seen before include "Dish" , "a cut above the others?" , "Towards ship's upper decks; part of cut of beef" , "Joint" , "Outer cut of beef" .)
