How to Sign "Siblings"
To sign 'siblings', you will combine the signs for 'brother' and 'sister' into one fluid motion. Form an 'L' shape (or a '1' shape) with your dominant hand. Briefly touch your thumb to your forehead, then move it down to touch your chin. Finally, bring your dominant hand down to rest on top of your non-dominant 'L' hand, with both index fingers pointing forward.
