How to Sign "Do" and "I Do" in American Sign Language

The short answer

In American Sign Language (ASL), the sign usually glossed as DO uses both hands in a C shape, palms facing down, moving together side to side in front of your body. This sign covers "do" as an action, as in doing something or keeping busy.

"I do" has no single sign. English uses "do" as a helper word, as in "Do you like coffee? I do." ASL generally does not sign that helper. You sign what the sentence means. That might be ME plus a nod, ME plus YES, or ME plus the actual action. The right choice depends on what "I do" is answering.

This guide describes ASL as used in the US. Other sign languages, such as British Sign Language, use different signs. No dictionary entries or instructor guidance were supplied for this article, so the descriptions below are general. Check them against a reputable ASL video dictionary or a Deaf ASL teacher, because regional and personal variation is common.

Which meaning of "do" do you need?

What you mean in English | How it is usually handled in ASL

"Do" as an action ("What are you doing?", "I do a lot") | The DO sign, or more often the specific action sign (WORK, CLEAN, STUDY)

"Do" as a question helper ("Do you want tea?") | Not signed; the question is shown with raised eyebrows and a slight head tilt

"I do" as a yes answer | ME (point to chest) with a nod, or ME + YES

"I do" as a wedding vow | Commonly ME + YES with a nod, or a sign such as AGREE or ACCEPT; couples often settle the wording ahead of time

"I do" for emphasis ("I do care") | Show emphasis with a firm nod and facial expression, sometimes adding TRUE or REALLY

How to sign DO, step by step

• 1. Shape both hands into the letter C, curving your fingers and thumb as if holding a small cup.
• 2. Turn both palms down so the C shapes face the floor.
• 3. Hold your hands in front of your body at about waist to chest height, a little apart.
• 4. Move both hands together to one side and back again, usually twice, in a small, relaxed motion.
• 5. Keep your face neutral for a statement, or raise or lower your eyebrows if you are asking a question.

There is also a related question form, often glossed DO-DO, meaning roughly "What should we do?" or "What are you doing?" Its handshape and movement differ from the basic DO sign, and it depends heavily on a questioning facial expression. Watch a video example before using it, because a written description is easy to misread.

How to sign "I do"

For "I" or "me," ASL uses a point to yourself. Extend your index finger and touch or point to the center of your chest. The fingerspelled letter I, with your pinky raised, is not the everyday pronoun in ASL.

• Answering a yes-or-no question: point to your chest and nod. You can add YES, which is a fist (S handshape) bobbing up and down at the wrist, like a nodding head.
• Describing an action you do: point to your chest, then sign the action itself, for example ME + WORK or ME + COOK. Use DO only when the action is general or unspecified.
• Wedding vows: ME + YES with a clear nod is a common choice. Some couples use AGREE or ACCEPT instead. If an interpreter will be there, agree on the exact signs with them beforehand.

In ASL, the nod and facial expression carry much of the meaning. A pointed "me" with a confident nod already reads as "I do" in many contexts.

How to check that you are signing it correctly

• 1. Watch a video dictionary example of DO and YES, paying attention to handshape, palm direction, location and movement.
• 2. Practice in front of a mirror, or record a short clip with your phone or webcam, and compare it side by side with the example.
• 3. Check four things: the handshape (C for DO, fist for YES), the palm direction (down for DO), the movement (side to side for DO) and your facial expression.
• 4. Ask a Deaf signer or ASL teacher for feedback if you can. They can confirm meaning and natural use, which a recording comparison can't.

Matching a video shows that your handshape and movement look like the example. It does not show that you chose the right sign for your sentence or that it sounds natural in context. Only feedback from fluent signers can check that.

Limitations and next steps

Signs vary by region, age group and community, and some people use English-based signing systems that sign "do" more literally. If you are preparing for something important, such as a wedding or a conversation with a Deaf family member, confirm your signs with the people involved or with a qualified interpreter. They can tell you which version is most natural for that audience.
