1.Airfoil: Cross sectional shape of a wing

2.Leading Edge: Front edge of wing

3.Trailing Edge: Back edge of wing 

4.Chord Line: A Line connecting Leading Edge to Trailing Edge

5.Camber Line: A line joining the leading and trailing edges of an airfoil equidistant from the upper and lower surfaces . High camber found on slow flying high lift aircraft.

6.Camber: It is the asymmetry between the top and the bottom curves of an aerofoil in cross-section.
