Leading edge:the front part of the airfoil
Chord line:center line that goes from the leading edge to the trailing edge
Angle of attack:the angle formed from the ground to the chord line
Trailing edge:the posterior of the airfoil
An airfoil is any part of the airplane that creates lift. This includes the wings, propeller, and Horizontal stabolizer. Lift is created two ways, and both have to do with the shape of the airfoil. Let's see how the airfoil creates lift.
