Ground near a ground? (5)
I believe the answer is:
arena
'ground?' is the definition.
(I've seen this before)
'ground near a' is the wordplay.
'ground' indicates anagramming the letters ('grind' the letters into a new form).
'near' is an anagram of 'aren'.
'aren'+'a'='ARENA'
(Other definitions for arena that I've seen before include "Olympic venue?" , "place for sporting contest" , "Scene of combat" , "Field of combat" , "Place for public events" .)
