Turn over, as a pancake (4)
I believe the answer is:
flip
'turn over as a pancake' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for flip that I've seen before include "Somersault - glib - hot drink" , "See red" , "Toss or flick in the air" , "hit the roof" , "Turn quickly over; sort of chart" .)
