Learn the four parts of a sign
The four parts of a sign include handshape, signing area, hand movement and palm position. If any of these change, so does the meaning of the sign.
Handshape: A handshape is the configuration of the hand during a particular sign. For example, many handshapes correspond with manual letters and numbers. So a sign with the same location, movement and palm position can actually mean different things, depending on the handshape. For example, motioning your hand in a circular, palm-in position over your chest area can mean "please" (with an open palm handshape) or "sorry" (with an "a" handshape).
Signing area: The same sign can also mean different things depending on its location. With few exceptions, the signing area itself is generally an imaginary rectangle that is shoulder-width and extends from the top of the head to just below the waist. Most signs are made in the area just below the face, head and neck.
Hand movement and palm position: A sign can mean one thing if the hand is still, and another if it's moved in a certain way. The same goes for which way the palm is facing (in toward yourself, out toward the other person, sideways, up or down).
An example of how these four elements can change things is how the sign for "I love you" can also mean "airplane" or "flying airplane." Each has the same hand position, but "I love you" is when the palm faces outward, "airplane" is when the palm faces downward (parallel to the floor), and "flying airplane" is when the hand faces downward and moves outward and away from the signer.
