Firstly, there are a lot of left-handed signers. There really is no difference except that your left hand is your dominant hand instead of your right hand. We touch on this a little bit in Unit 3. This is what it says:
You have a dominant and non-dominant hand. If you are right-handed, your right hand is your dominant hand. If you are left-handed, your left hand is your dominant hand. If you are ambidextrous, choose one hand to use as your dominant hand, and stick with it. It is important to know your dominant hand because it affects the way you will sign. There are three types of signs when it comes to what hand you will use:
- One-handed signs
Uses only your dominant hand.
- Two-handed symmetrical signs
Uses both your dominant and non-dominant hand where they both move the same way
- Two-handed non-symmetrical signs
Uses both your dominant and non-dominant hand where the dominant hand moves while the non-dominant hand remains stationary.
Your non-dominant hand will never move unless your dominant hand is moving the same way. Remember this, because figuring out which hand to use is difficult with more complicated signs and descriptions.
