how to sign the word achordate

To sign the word “achordate,” use the ASL sign for “no” by making a fist with your dominant hand, then extending your index and middle fingers. Place those fingers on either side of your forehead, with your palm facing outward. Then, make a small circular motion with your wrist while keeping your fingers in the same position. This gesture represents the lack of a spinal cord, which is the defining characteristic of an “achordate” organism.
