A circle to draw (5)
I believe the answer is:
lotto
'draw' is the definition.
(I've seen this before)
'a circle to' is the wordplay.
'a circle' becomes 'lot' ('lot' can be a synonym of 'circle').
'lot'+'to'='LOTTO'
(Other definitions for lotto that I've seen before include "Children's game similar to bingo" , "National game with large money prizes" , "Game like bingo" , "gamble" , "Lucky draw" .)
