What is the difference between engine turn over vs start?

"TURNING OVER AN ENGINE" REFERS TO ROTATING THE CRANKSHAFT, USUALLY BY MEANS OF THE STARTER MOTOR AND THE RING GEAR, IF IT WAS AN OLDER ENGINE YOU COULD USE THE CRANK HANDLE THOUGH THESE WENT OUT OF FASHION DUE TO HIGHER CRANKING SPEED BEING REQUIRED TO START AN ENGINE. PUSHING THE VEHICLE (IF IT WAS MANUAL) WHILE IN GEAR WOULD ALSO TURN THE ENGINE OVER BUT MAKE SURE THE IGNITION WAS SWITCHED OFF UNLESS YOU WANT IT TO START.
