Thank You in Sign Language: ASL, Baby Sign & Global Variations

You’ve seen the ASL sign for thank you in a video or a GIF and wondered whether your hand is doing the right thing — the good news is it’s a single, graceful motion: a flat hand near the chin moving outward toward the person, as Signing Time (children’s sign language program) describes it. Here’s how to get the handshape and direction right, why beginners confuse it with GOOD, and what changes in baby sign and other signed languages.

Typical teaching age: 12–18 months ·
Starting point: chin or lower lip, palm facing in ·
Direction: toward the person being thanked ·
Common misconception: the sign is not a blown kiss

Six entries, one pattern: the sign is a flat hand with a clear start, a clear path, and a clear target — and every common mistake comes from blurring one of those.

Nothing here requires flexibility or talent — just consistency. That’s exactly why the sign shows up in nearly every beginner ASL and baby sign list.

How do you sign thank you in American Sign Language?

THANK-YOU and GOOD are the two signs beginners mix up most, because both begin near the mouth or chin. The difference is movement: THANK-YOU travels forward toward the person, while GOOD drops down into the opposite palm (Pocket Sign (ASL learning app)). The same distinction is covered in more detail in thank-you vs. good in ASL.

What is the correct hand shape?

• Flat open hand, fingers together, thumb extended
• Use your dominant hand; left-handed signers use the left
• Palm faces inward as the hand rises toward the chin

The shape is simple on purpose: the meaning is carried by where the hand goes, not by how fancy the hand looks.

Where does the movement start and end?

• Start: fingertips at the chin or lower mouth
• Move: outward and slightly downward, finishing palm-up toward the person
• Aim: the motion travels toward the person being thanked

Instructors disagree on the exact starting point — some say the lips, others the chin — but the outward motion of the open hand is the consistent feature.

How to emphasize the sign with facial expressions

• Smile or nod as the hand moves
• Hold eye contact through the whole sign
• Let the expression complete the phrase, not the hand

The face is not decoration. In ASL, non-manual signals — the smile, the nod, the raised brow — share the grammatical load, and a thank-you delivered with a blank face reads as a different message.

The implication: the sign is a system of contrasts. Same hand, same starting point, different direction — and you get a different word.

How do you sign thank you in other sign languages?

ASL is one language in a diverse family. BabyCenter points out that baby sign language is not automatically identical to ASL — and the same logic applies to adult signed languages: each one has its own vocabulary, grammar, and politeness conventions (BabyCenter (parenting resource)). If you learn “thank you” in ASL and assume it travels, you’ll be signing in the wrong language.

British Sign Language (BSL) version

• BSL is a separate language, not ASL with a British accent
• Its thank-you sign is commonly two-handed, moving forward from the chest

The two-handed form is a useful visual cue: if you see both hands leave the chest, you’re watching BSL or a regional cousin, not ASL.

Japanese Sign Language (JSL) version

• JSL uses a handshape similar to ASL’s open palm, but with a different orientation
• JSL has its own grammar and vocabulary

The practical rule is the same: learn the local sign rather than importing one from home.

Korean Sign Language (KSL) version

• KSL’s thank-you often uses two hands moving forward together
• It reads as a fuller, more deliberate gesture than a one-handed flick

If you’re meeting deaf colleagues or clients in Seoul, don’t bring your ASL habit with you — learn the KSL form and let the people around you guide the nuance.

Indonesian Sign Language (BISINDO) version

• BISINDO’s sign for thank you may involve a repeated forward motion rather than a single arc
• Local variants exist across Indonesia, so regional guidance matters

Across all four examples, one pattern holds: gratitude moves forward, toward the other person, and each signed language shapes that movement in its own grammar.

How do you teach or use thank you in sign language with babies and in everyday communication?

With a baby, the sign works because it’s visible, quick, and tied to a feeling they already have when someone hands them something. The method is a rhythm, not a drill.

When to start teaching thank you to a baby

• Around 12–18 months is the typical window
• Start at natural moments: food, help, a toy
• Don’t force it — let the baby observe first

The consistency routine matters more than any calendar date: same sign, same spoken word, same action, every time (Healthy Mom & Baby (parenting advice site)).

How to model the sign consistently

• Pair the sign with the spoken words “thank you”
• Sign slowly, at the baby’s eye level
• Keep the face warm — a smile makes the sign legible

The loop is simple: show the sign, pause, respond warmly when the attempt comes.

How to respond when a baby signs thank you

• Wait 5–10 seconds before repeating the model
• Smile and praise any attempt
• Sign the word back to confirm the exchange

The pause is the pedagogical secret. Five to ten seconds is enough time for a baby to notice, process, and try — and then your reaction becomes the reward.

Using thank you in conversation with deaf adults

• Aim the sign at the person — THANK-YOU is directional
• Add a nod and hold eye contact
• One well-formed sign is a complete, courteous message

The gratitude is read through the face as much as the hand. A sign that travels toward the other person without eye contact feels rehearsed; with a nod, it lands.

Step-by-step: teach the sign in five rounds a day

One full round takes about twenty seconds. The trick is repetition at the right moments.

1. Shape the hand. Flat open palm, fingers together, thumb extended — the starting frame.
2. Touch the chin. Bring the fingertips to the chin or lower lip, palm facing you.
3. Move outward. Slide the hand forward and slightly down, ending with the palm open toward the person.
4. Add the face. Nod or smile as the hand moves — this is what makes it a thank-you.
5. Wait and repeat. Give the baby 5–10 seconds, then model the sign again if there’s no response.

The pattern: every round ends the same way — sign, wait, smile, repeat — until the sign becomes as automatic as the gratitude it expresses.

Separating confirmed facts from unanswered questions

The sources agree on the mechanics but stay silent on the history. Here’s where the evidence is solid and where it isn’t.

Confirmed facts

• THANK-YOU starts at the chin or lower mouth, palm facing inward — location and orientation are part of its grammar (Pocket Sign (ASL learning app))
• The sign is directional: the outward movement is aimed at the person being thanked (ASL Teaching Resources (ASL curriculum site))

What’s unclear

• The symbolic origin of the chin/lip placement — none of the reviewed sources documents it
• Whether the sign starts at the lips or the chin — descriptions genuinely differ
• Whether THANK-YOU and YOU’RE-WELCOME are truly the same sign in adult ASL — baby sign materials often teach them as one
• Whether a single thank-you gesture works across all signed languages — it does not; each signed language has its own form

The pattern: the mechanics are settled, but the cultural history is not — and for a learner, that’s the right split to respect.

Sign language references, in their own words

The teaching guides agree on three things: the sign is physical, it is directional, and it doesn’t work without the face.

Combine the sign with a pleasant facial expression, smile, or nod when modeling gratitude.

— Signing Time’s ASL dictionary (children’s sign language program)

Some instructional sources describe the starting location as the lips or mouth rather than the chin; the relevant feature is the outward movement of the open hand.

— Gryphon House’s 10 Simple Signs for Babies (early childhood education publisher)

The common thread: neither reference treats the sign as a gesture alone. Each one anchors it in relationship — to a child, to a conversation, to a culture.

The sign for thank you is one of the few gestures that works the same in a nursery, a classroom, and a Deaf conversation — once you respect its grammar. For parents starting baby sign at home, the choice is clear: model the flat-hand motion with the spoken words at real moments of gratitude, or the handshape will blur into GOOD and the message will be lost entirely. And for hearing adults greeting Deaf colleagues, the implication is equally direct: use the directional movement with a nod and eye contact, or fall back on a blown kiss that was never really ASL.
