Neighbour roughly chucking out ball? (4)
I believe the answer is:
abut
'neighbour' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for abut that I've seen before include "Neighbour" , "Impinge" , "Of building or land, end or lean against" , "Adjoin -- 19 (rev)" , "Be next to -- share a boundary" .)
