How to Sign "Did" in Sign Language

The short answer

In American Sign Language (ASL), there usually is no separate sign that matches the English word "did." English uses "did" as a helper word for past tense, questions and emphasis. ASL handles those jobs differently, with time signs, sentence context, facial expressions and the signs for the actions themselves. So the right way to sign "did" depends on what the English sentence is doing.

One ambiguity matters here. If you are learning an English-based signing system rather than ASL, such as Signing Exact English, that system is designed to represent English words and word endings more directly and may have a form for "did." Those systems are not the same language as ASL. Check which one your class, school or conversation partner uses before you memorize a form.

Match the meaning of "did" first

Before you sign anything, decide which of these jobs "did" is doing in your sentence.

English use | Example | General ASL approach

Past tense | "I did my homework." | Sign the action and show that it is in the past, often with a time sign or a sign meaning finished.

Yes/no question | "Did you eat?" | Sign the action and the person, and use question facial grammar. The word "did" itself is not signed.

Emphasis or confirmation | "I did lock the door." | Show emphasis through facial expression, head movement or a sign meaning true or really.

"Did" as the main verb (to do) | "What did you do?" | Use the ASL sign for do, with question facial grammar.

How to show a past action

ASL generally sets the time of a conversation near the start, and that time frame carries forward until it changes. You do not need to mark every verb as past tense the way English does.

• Establish when the action happened, using a time sign such as yesterday, last week or a general sign for the past.
• Sign the action itself, such as eat, go or work.
• If the point is that something is complete, a sign commonly glossed as FINISH can show that the action is done.
• Keep the same time frame for later sentences unless you change it.

For example, to say "I did my homework yesterday," ASL would typically show yesterday, homework and the action or completion. It would not sign a separate "did."

How to ask a "did you" question

In ASL, facial expression is part of the grammar, not just emotion. For a yes/no question such as "Did you eat?", the face carries the question.

• Sign the main idea, such as you and eat. Add a time sign or a completion sign if the time is not already clear.
• Raise your eyebrows during the question. This is the standard marker for a yes/no question in ASL.
• You may lean your head or body slightly forward and hold eye contact at the end so the other person knows it is their turn.
• For a "what did you do" question, which asks for information, ASL typically uses lowered or furrowed eyebrows and a question sign such as what.

If your eyebrows stay neutral, the same signs can read as a statement ("You ate") rather than a question. This is one of the most common learner mistakes.

How to show emphasis

When English speakers stress "did" ("I did call you!"), ASL usually conveys that through a firm facial expression, a head nod, or a sign meaning true or really before the action. The emphasis comes from how you sign, not from an extra word for "did."

How to know you got it right

• Ask a fluent signer to watch you sign the full sentence, not just the word. Whether they understand the meaning is the real test.
• Check that your questions are recognized as questions without any extra explanation. If they are not, look at your eyebrows first.
• Confirm the time frame was understood by asking the other person when they think the action happened.

Limits of this guide

This guide describes general ASL grammar principles. It does not give exact handshapes or movements, because those are best learned by watching a signer, and written descriptions are easy to misread. Signs and preferences also vary by region, community and generation. Other sign languages, such as British Sign Language, have their own grammar and vocabulary. For the precise forms of signs like FINISH, PAST or DO, learn from a Deaf instructor, a qualified ASL teacher or a video dictionary made by fluent signers.
