Cricket square here almost round (4)
I believe the answer is:
oval
'almost round' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for oval that I've seen before include "Elliptical figure" , "6D 5A [TUBE STATION]" , "Easter gift" , "Race track" , "Test site" .)
