Goes over the ground where the knights used to fight (5)
I believe the answer is:
lists
'goes' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Perhaps you can see a link between them that I don't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for lists that I've seen before include "Heels; rolls" , "Tips" , "Scene of combat - catalogues" , "Catalogues, rolls" , "Itemises" .)
