Schoolyard friend (8)
I believe the answer is:
playmate
'schoolyard friend' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for playmate that I've seen before include "My palate (anag.)" , "Chum; Ate my pal (anag.)" , "fun chum" , "Childhood companion" , "Companion for fun" .)
