Wait around The Point to change direction suddenly (6)
I believe the answer is:
swerve
'change direction suddenly' is the definition.
(I've seen this before)
'wait around the point' is the wordplay.
'wait' becomes 'serve' (I've seen this before).
'around' is an insertion indicator.
'the point' becomes 'w' (W is an example).
'serve' going around 'w' is 'SWERVE'.
'to' acts as a link.
(Other definitions for swerve that I've seen before include "Abrupt change of course" , "Suddenly move off course" , "Turn aside from straight course to avoid something (6)" , "Change course abruptly" , "Change course suddenly" .)
