What does it mean exactly to stall a manual car?

Engines have very little power and torque at idle speed. A good way to learn to drive manual transmission is to stop on a flat road. Take your right foot off the gas and slowly let out the clutch without stalling the car. This is a good way for beginners to learn how to start off in first gear. If you let the clutch out too fast the engine will stall. One you get the feel of the clutch, you add gas while letting out the clutch for a smooth start.
