how to sign the word addititious

To sign addititious, first form the letter ‘A’ with your dominant hand and place it on top of your other hand, palm facing up. Then twist your wrist slightly and bring your thumb and index finger together to create a circular motion. This represents the ‘dd’ sound in the word. Finally, continue the circular motion with just your dominant hand while lowering it and tapping the back of your non-dominant hand to represent the ‘ititious’ ending.
