How to Sign "Adult"

To sign adult, start by raising both hands to about head or shoulder height, positioned slightly out to the sides of your body. Form both hands into a 'bent B' handshape—keep your fingers straight and close together, but bend them at a 90-degree angle at the base knuckles. With your palms facing down and fingers pointing forward, hold or slightly move the hands upward. This gesture visually represents the tall physical height of a fully grown person.

How to Sign "Adult"
To sign adult, start by raising both hands to about head or shoulder height, positioned slightly out to the sides of your body. Form both hands into a 'bent B' handshape—keep your fingers straight and close together, but bend them at a 90-degree angle at the base knuckles. With your palms facing down and fingers pointing forward, hold or slightly move the hands upward. This gesture visually represents the tall physical height of a fully grown person.
Visual Logic(Etymology)
The sign for adult is highly iconic and visually motivated, meaning it looks exactly like what it represents. By placing your hands at head level with the palms facing down, you are literally marking the physical height of a fully grown person in the space around you. The 'bent B' handshape specifically acts as a visual marker for the top of a human head. This spatial representation perfectly captures the transition from growing up to reaching full adult stature.
Signing Tips
When signing adult, focus on the crispness of your 'bent B' handshape. Keep your fingers tightly together and bend strictly at the base knuckles, avoiding any curve in the fingers themselves. Position your hands at a realistic height for a grown person—usually around your own head level or slightly higher. Using both hands emphasizes the concept of adults in general or a group of adults, though you may sometimes see it signed with just your dominant hand in casual, everyday conversation.
Common Mistakes
A common mistake for beginners is using flat, open hands instead of bending them at the knuckles. In ASL, a flat hand with the palm down is typically used to indicate the height of animals or inanimate objects. The 'bent B' handshape, however, is specifically reserved for the height of people. Additionally, be careful not to place your hands too low. Holding the hands at chest or waist level changes the meaning entirely, indicating a child or teenager rather than a grown adult.
Regional Variations
While the height-based sign shown here is widely understood and beautifully visual, another very common variation exists that uses the 'A' handshape. In this initialized version, the thumb of the 'A' hand touches the side of the chin and then moves up to touch the side of the forehead. This variation borrows the traditional locations used for 'mother' and 'father' to represent a grown person. You will likely encounter both versions depending on the region and the signer's background.

Frequently Asked Questions
Is there another way to sign adult?

Yes! A very common alternative uses an initialized 'A' handshape. You touch the thumb of your 'A' hand to the side of your chin, then move it up to touch the side of your forehead. Both the height-based version and the initialized version are widely used across the Deaf community.

Can this sign also mean tall?

Yes, depending entirely on the context of your sentence, this exact sign can be used to mean tall. When you hold the 'bent B' handshape high up, it describes the physical height of a person, which naturally translates to both the concept of an adult and being tall.

Why do we bend the fingers for this sign?

In ASL, the 'bent B' handshape is a specific classifier used to indicate the height of a human being. If you were to use a flat, open hand with the palm facing down, it would typically refer to the height of an animal, like a dog, or an inanimate object.
