How to Say Thank You in Sign Language: ASL & BSL Guide

Every new signer knows the moment: you nail the sign for “thank you,” only to realize “good” uses nearly the same handshape — the difference is just a few inches of trajectory, and it’s the most common mix-up in ASL classrooms. If you’re learning American Sign Language or British Sign Language, the movement is simple, but the two systems are genuinely different languages — the National Institute on Deafness and Other Communication Disorders is explicit that no universal sign language exists — and the facial grammar that accompanies “thank you” is part of the sign itself.

ASL signer base: United States and parts of Canada and Mexico (University of Chicago) ·
Handshape for “thank you”: flat B-handshape, fingers together, thumb out (Strong ASL) ·
Movement: forward and down, ending palm-up (Strong ASL) ·
Documented as a language: 1960s, William Stokoe’s research (University of Chicago) ·
Universal sign language? No — ASL and BSL are distinct (NIDCD)

Eight facts, one pattern: each language has a stable thank-you sign, but ASL and BSL are independent systems.

How Do You Say Thank You in Sign Language?

Start with the production that ASL dictionaries use, then adapt it if you’re learning British Sign Language.

Step-by-Step ASL Guide to Signing Thank You

• Handshape and start: form a flat hand — fingers together, thumb extended — and bring it to your chin, palm facing you (Strong ASL).
• Move: sweep the hand forward and down, ending with the palm up, facing the person you’re thanking (Strong ASL).
• Add the nonmanual part: a small head nod and a warm, relaxed face. In ASL, facial movement carries grammar, not just feeling (NIDCD).

That’s the entire sign. Note what it doesn’t do: it doesn’t stay at the chin, and it doesn’t travel sideways. The outward-down trajectory — especially the palm-up finish — is what makes the sign readable as “thank you” rather than a similar word.

British Sign Language (BSL) Version

• Handshape: the same flat hand you’d use in ASL.
• Start: at or near the chin.
• Move: outward, with the palm often facing the person you’re thanking.
• The warning: BSL and ASL are separate languages. An ASL signer should not assume they’ll be understood in the UK (NIDCD).

If your conversations happen in the UK, learn BSL; if they happen in the US or in parts of Canada and Mexico, learn ASL (University of Chicago). The “thank you” signs look similar — but a shared-looking sign is not a shared language.

What Is the Difference Between Good and Thank You in ASL?

The confusion isn’t a memory problem — it’s a design feature of ASL. The two signs share a handshape and a starting point; the contrast lives entirely in the movement.

Breaking Down the Sign for Good in ASL

• Handshape: the same flat hand you use for “thank you.”
• Start: at the chin.
• Move: downward, finishing on the open palm of your non-dominant hand.
• Meaning: approval — “this is good,” “that works.”

Good stays close to your body. The hand travels down and lands; it doesn’t leave you.

Key Visual Differences and Common Mistakes

• Thank you: chin → outward → palm-up finish (Strong ASL).
• Good: chin → down → palm contact.
• The most common mistake: start the movement correctly, then send it down instead of out — producing “good” when you meant “thank you.”

Freeze the first frame of either sign and you’ll struggle to tell them apart. That’s because ASL distinguishes words through movement — one of the four parameters (handshape, location, movement, orientation) that linguists use to describe signs (University of Chicago).

The pattern: one shared start, two different endings. Get the ending right and you’ve eliminated the most common politeness error in ASL.

How Do You Say You’re Welcome and Please in Sign Language?

“Thank you” never travels alone. In conversation it pairs with please and you’re welcome — and each sign has its own anchor point on the body.

Signing You’re Welcome in ASL

• Handshape: flat hand, thumb out.
• Start: at the chest.
• Move: outward, away from the body.

The direction mirrors “thank you,” but the starting point is the chest rather than the chin. That shared outward motion is why beginners mix up the two signs.

Signing Please in ASL

• Handshape: flat hand.
• Placement: on the chest, over the heart.
• Move: a small circular rub.

Instructors often describe it as a polite rub of the heart. Because the sign is one-handed, you can produce it while holding a bag or a cup — the non-dominant hand stays free.

What this means: the polite set is a family of torso-anchored signs — chest for please and you’re welcome, chin for thank you. Change the anchor point and you change the word.

How Do You Sign Thankful and Everything in ASL?

Once you know the base sign, ASL gives you ways to modify it. That’s the same parameter system — handshape, location, movement, orientation — that linguists use to describe the language (University of Chicago).

Expanding Your Vocabulary: Signing Thankful

• Base: the thank-you handshape at the chin.
• Modification: often both hands, with a fuller and slower movement.
• Meaning: gratitude as a state of mind, not just a quick reply.

You’re not memorizing an unrelated word; you’re extending a sign you already know.

Signing the Concept of Everything

• Handshape: both flat hands.
• Move: a sweeping pass across the body.
• Meaning: “all of it” — a broad, inclusive sweep.

Everything is a good second lesson in two-handed signs because the rhythm and the sweep are easy to see and copy.

The takeaway: ASL builds nuance by altering base signs. The four parameters aren’t abstract theory — they’re the difference between “thank you,” “thankful,” and “everything.”

What Is the ASL Alphabet?

The alphabet is where handshape precision gets trained, because handshape is one of the four contrastive parameters that structure all of ASL (University of Chicago).

Learning the 26 Handshapes of Fingerspelling

• Count: 26 manual handshapes, one for each letter of written English.
• Use: proper names, brands, terms without established signs, and clarified words.
• Skill: fingerspelling is the standard entry point for looking up unfamiliar signs in ASL dictionaries.

The alphabet matters beyond spelling: it forces your hand into clean, distinct positions, which carries over into every other sign you learn.

Using Fingerspelling to Spell Thank You

• The word: T-H-A-N-K Y-O-U in sequence.
• When to use it: for emphasis or extra clarity — not as the everyday default.
• The default: the lexical sign you learned at the chin is what native signers use in normal conversation.

Why this matters: the alphabet isn’t a separate skill from signing “thank you.” Both run on the same requirement — clean, deliberate handshapes.

Good vs. Thank You: Side-by-Side

Set the two signs next to each other and the one contrast that separates them becomes impossible to miss.

The catch: on a muted video, this difference is almost invisible. In person, it’s unmistakable — because the destination of the hand does the grammatical work (University of Chicago).

The trade-off: you can memorize the two signs separately, but it’s faster to learn the single rule — thank you leaves, good lands.

Step-by-Step Practice Plan for Polite Signs

Don’t drill signs in isolation. The sequence below moves from the easiest anchor point to the trickiest contrast.

1. Please — flat hand circles over the chest. The chest is your home base.
2. Thank you — the same flat hand moves from the chin outward and down to a palm-up finish (Strong ASL).
3. You’re welcome — from the chest, sweep the hand outward.
4. Good vs. thank you — alternate the two signs slowly, watching the destination: down for good, outward for thank you.
5. Thankful — repeat thank you with both hands, slower and fuller.

Run the sequence once a day for a week. Speed is not the goal; keeping each trajectory separate is the goal.

The pattern: the sequence works because it isolates one contrast at a time before inviting you to combine them in a real exchange.

Confirmed Facts and What’s Still Unclear

Here’s the honest map of the evidence: some things about signing “thank you” are settled, and a few genuinely are not documented.

The implication: the unclear items are a reason to treat any single tutorial as a starting point, not a final verdict — including this one.

Quotes From the Field

“In commonly published ASL instructions, begin with the dominant hand covering the mouth, palm facing inward. Use extended fingers held together with the thumb extended to the side. Move the hand forward and downward, finishing with the palm oriented upward.”

Strong ASL — American Sign Language Dictionary

“ASL is a complete natural language with its own linguistic properties and grammar distinct from spoken English. There is no single universal sign language. ASL is expressed through movements of the hands and face.”

National Institute on Deafness and Other Communication Disorders (US National Institutes of Health)

“ASL is not a form of signed English; it is a distinct linguistic system. A useful description of an ASL sign can include handshape, location, movement type, and palm orientation.”

University of Chicago — linguistics course materials on sign language

Why these quotes matter: they all describe the same underlying reality — ASL is a full language, and “thank you” is a linguistic sign with grammar attached, not a gesture.

The Takeaway

The sign for “thank you” is one of the easiest in ASL to recognize and one of the easiest to get subtly wrong, because its closest neighbor — “good” — sits in nearly the same visual space. The fix is entirely in the movement: outward and down to a palm-up finish, with a nod that says the thanks is genuine. For a new ASL learner, the decision is clear: practice the trajectory until it’s automatic, or keep producing “good” at the exact moment you want to say thank you.
