How to Sign "Son" in American Sign Language

The short answer

In American Sign Language (ASL), SON is commonly signed by combining two ideas: "male" and "baby." Your dominant hand starts near your forehead, where many ASL signs for male family members begin. It then moves down and settles, palm up, into the crook of your other arm, which is held across your body as if you were cradling an infant.

This guide covers ASL, the sign language most used in the United States. Other sign languages, such as British Sign Language or Auslan, are separate languages with their own vocabulary, so their sign for son may look different. If you are learning for a specific person or community, confirm which sign language they use.

Step-by-step: signing SON

• 1. Hold your non-dominant arm across your body at about waist or lower-chest height, palm facing up, as if you were ready to hold a baby.
• 2. Raise your dominant hand to your forehead. Most signers use a flat hand with the fingers together, touching or nearly touching the forehead, similar to a small salute.
• 3. Bring your dominant hand down in a smooth arc toward your other arm.
• 4. Finish with your dominant hand resting palm up in the bend of your non-dominant arm, so your two arms look like they are cradling something.
• 5. Keep the motion to one clear movement. You do not need to rock your arms the way you would for the separate sign BABY.

Why the sign looks the way it does

Many ASL family signs follow a location pattern. Signs for male relatives, such as father, brother, grandfather and son, typically begin at or near the forehead. Signs for female relatives typically begin lower, at the chin or jaw. Knowing this pattern makes related signs easier to remember and helps you avoid mixing them up.

Sign | Starting point | Ending

SON | Forehead (male area) | Dominant hand resting palm up in the crook of the other arm

DAUGHTER | Chin or jaw line (female area) | Same cradled ending as SON

BABY | No forehead or chin start | Both arms cradled together, often with a gentle rocking motion

Common variations

You may see signers start SON with a slightly different handshape. Some begin with the fingers bunched at the forehead, as if gripping the brim of a cap (the sign for BOY), and then open the hand flat as it drops to the arm. Both versions follow the same idea and are generally understood. Regional and personal variation is normal in ASL, so it is worth asking the people you sign with which form they use.

Saying "my son"

To sign "my son," place your flat dominant hand, palm in, against the center of your chest for MY, then sign SON. ASL word order and grammar differ from English, so in full sentences the sign may not always appear where it would in an English sentence.

How to check that you are signing it clearly

• Location: your dominant hand clearly starts at the forehead, not the chin. Starting at the chin turns the sign into DAUGHTER.
• Ending: your dominant hand lands palm up on the inside of your other forearm, not on the back of it.
• Movement: the hand travels in one smooth path from forehead to arm without stopping halfway.
• Arms: your non-dominant arm stays still and steady as the base of the sign.

Practicing in front of a mirror lets you check location and handshape, but it cannot confirm whether your signing reads naturally to a fluent signer. For that, the most reliable check is feedback from a Deaf signer, a qualified ASL instructor or a reputable ASL video dictionary where you can compare your movement against a demonstration.

Limitations of a written description

Sign language is visual and depends on movement, handshape, palm orientation and facial expression together. Written steps can describe the basic form, but they cannot show speed, rhythm or the subtle differences between variants. No verified demonstration or source material was supplied for this guide, so treat it as a starting point and confirm the sign with a fluent signer or a video reference before relying on it in conversation.
