Stopped around summit (3)
I believe the answer is:
top
'summit' is the definition.
(I know that summit can be written as top)
'stopped around' is the wordplay.
'around' indicates the answer is hidden within the clue.
'TOP' is hidden within 'stopped'.
(Other definitions for top that I've seen before include "Toy; uppermost point" , "Zenith" , "Highest point or position" , "Toy; garment" , "Peak; child's toy" .)
