How to Sign DO in ASL: Video Guide & Grammar Rules


English relies on the word “do” as an all-purpose linguistic workhorse. You use it to inquire about someone’s evening (“What are you doing?”), confirm a preference (“Do you want tea?”), assign an activity (“Do your chores”), or emphasize a conviction (“I do want to attend”).

When beginners transition from spoken English to visual communication, they frequently search for a single, direct equivalent for “do.” That word-for-word translation does not exist in American Sign Language (ASL).

Treating ASL as a carbon copy of English spoken syntax leads to immediate miscommunication. In sign language, meaning governs form. Depending on whether you are asking a question, describing an activity, or formulating an inquiry, you will use a lexicalized loan sign, a distinct action verb, or drop the word altogether.


Quick Answer: How Do You Sign “DO” in American Sign Language?

To sign “DO” in American Sign Language (ASL), turn both palms upward at chest level and rapidly pinch your index fingers to your thumbs twice (#DO-DO). For physical tasks or activities, sweep both palms downward in horizontal circles (ACTION). Never sign “DO” for English auxiliary questions; ASL uses facial markers instead.

The Two Core ASL Signs for “DO”: Semantic Disambiguation

To sign accurately, you must identify whether your sentence asks a question about an activity or describes the execution of a task.

1. The Interrogative Loan Sign (#DO-DO): “What are you doing?”

When inquiring about someone’s current actions, plans, or intentions, use the lexicalized loan sign transcribed in ASL gloss as #DO-DO (sometimes written as #DO).

Linguist Robbin Battison classified this sign as a Type 3 lexicalized fingerspelled loan sign. It originated as the rapid fingerspelling of the letters D and O. Over decades of natural phonological assimilation within the Deaf community, the discrete fingerspelled letters merged into a fluid, two-handed morpheme where the fingers transition from an open position into a closed pinch.

Use #DO-DO exclusively for inquiries such as:

  • “What are you doing?”
  • “What did you do today?”
  • “What should we do now?”

2. The Performative Action Sign (ACTION / PERFORM): “Executing Tasks”

When “do” functions as a transitive verb indicating labor, chores, performances, or completing a task, never sign #DO-DO. Instead, use the general action verb ACTION (also glossed as ACTIVITY or PERFORM).

Use ACTION for statements such as:

  • “I have to do my chores.”
  • “We did business together.”
  • “What kind of work do you do?” (Used in combination with WORK).

Step-by-Step Mechanics: The 5 Phonological Parameters of #DO-DO

In 1960, Dr. William Stokoe demonstrated that visual languages consist of structured structural units, now recognized as the 5 Phonological Parameters of ASL. Missing even one parameter alters the sign’s meaning or renders it incomprehensible.

“`| Handshape | Modified “G” transitioning to a pinched “O” handshape |
| Palm Orientation | Supinated (palms facing upward toward the ceiling/torso) |
| Location | Neutral physical space at mid-chest level |
| Movement | Rapid, double rhythmic pinch (closing index fingers to thumbs) |
| Non-Manual Marker| Furrowed eyebrows, slight head tilt forward (WH-Question marker)|| ASL vs. BSL: STRUCTURAL COMPARISON |“`

If communicating with a BSL user, the ASL #DO-DO loan sign will not be understood. BSL forms the sign for “do” through a two-handed system, reflecting its distinct historical phonology.


Common Conversational Phrases Using “DO”

How to Sign “What are you doing?”

  • ASL Gloss: YOU #DO-DO?
  • Execution: Point your dominant index finger toward your partner (YOU), transition both hands directly into the neutral chest space with palms up, and pinch your index fingers to your thumbs twice (#DO-DO).
  • Facial Grammar: Keep your eyebrows furrowed throughout the entire phrase.

How to Sign “Do your homework”

  • ASL Gloss: YOUR HOMEWORK, DO!
  • Execution: Push your flat open palm outward toward your partner (YOUR). Touch your dominant flat hand to your cheek then chin, followed by tapping two flat hands together (HOMEWORK). Finish by moving both palms downward in parallel horizontal arcs (ACTION/PERFORM).
  • Facial Grammar: Neutral brows with firm, focused mouth movement.

How to Sign “Do you mind?”

  • ASL Gloss: DON'T-MIND?
  • Execution: English speakers often attempt to sign DO + YOU + MIND. In ASL, this is expressed using a single idiomatic lexical item. Touch the tip of your dominant index finger to the tip of your nose, then sweep your hand downward and outward in an arc away from your face.
  • Facial Grammar: Raise your eyebrows high and tilt your head to mark the question as a polite Yes/No inquiry.

Frequently Asked Questions

Why is the conversational sign for “DO” fingerspelled?

The sign #DO-DO is a lexicalized fingerspelled loan sign. It originated from the English letters D and O fingerspelled in quick succession. Over time, natural phonological assimilation within Deaf culture combined the handshapes into a unified, repeating two-handed morpheme.

Do you sign “DO” in questions like “Do you like tea?”

No. Never sign “DO” for auxiliary English questions. In ASL, auxiliary verbs are omitted. Simply sign TEA, YOU LIKE? while raising your eyebrows and tilting your head forward to signal a Yes/No question visually.

What is the difference between #DO-DO and ACTION?

#DO-DO is an interrogative loan sign used exclusively to ask what someone is doing or what should be done. ACTION is an active verb formed with palms facing downward moving in horizontal circles, used to describe tasks, work, activities, or general performance.

How do you sign “don’t” in ASL?

To express “don’t,” ASL uses head-shaking negation while signing the verb. For an explicit command (“Don’t touch that!”), cross both flat open hands at the wrists with palms facing down and sweep them forcefully apart to the sides, or flick your dominant thumb forward from beneath your chin to sign NOT.
