Thought in Sign Language: How to Sign THINK and THOUGHT in ASL

The short answer

In American Sign Language (ASL), THINK is usually signed by touching the tip of your dominant index finger to your forehead or the side of your forehead. THOUGHT, or the ongoing act of THINKING, is commonly shown with the same handshape making a small circle near the forehead instead of a single touch. Both signs place the idea at the head, where thinking happens.

This guide does not draw on a cited ASL dictionary or video source. The descriptions reflect widely taught forms, but regional and personal variation exists. Before relying on a sign in an important conversation, confirm it with a Deaf signer, a qualified ASL instructor or a reputable ASL video dictionary.

Two things that can change the answer

Which sign language you mean. Sign languages are separate languages, not signed versions of English or Russian. This article covers ASL, the main sign language in the United States. If you searched for how to show think and thought in Russian, you may need Russian Sign Language (RSL), which has its own vocabulary. Do not assume an ASL sign means the same thing, or anything, in RSL, British Sign Language or another sign language.

Which meaning of the phrase you mean. "Thought in sign language" usually means how to sign the word. "Thinks in sign language" usually means something else: whether a person's inner thinking happens in signs. Both are covered below.

How to sign THINK, step by step

• 1. Use your dominant hand, the one you write with. Left-handed signers mirror the sign; that is normal and correct.
• 2. Make a fist and extend only your index finger.
• 3. Bring the fingertip to your forehead or the side of your forehead, near the temple.
• 4. Touch briefly and lower your hand, or move on to the next sign.
• 5. Keep your face neutral or match it to what you mean, such as a slight frown for careful thought.

How to sign THOUGHT or THINKING

• 1. Use the same index-finger handshape as THINK.
• 2. Hold the fingertip close to your forehead or temple without pressing in.
• 3. Make a small, relaxed circle with the fingertip in front of that spot.
• 4. Repeat the circle once or twice. In context, the repetition shows ongoing or reflective thought.
• 5. Let your facial expression carry the mood, such as thoughtful, puzzled or absorbed.

The circling movement also appears in signs related to wondering or pondering. Signers often tell these apart by context and facial expression, not by the hand alone. This is one reason to check the exact form you need with a fluent signer.

Why the face matters as much as the hand

ASL uses facial expressions and head movements, called non-manual markers, as part of the grammar. A raised brow can turn a statement into a yes-or-no question. A furrowed brow often appears with questions like what or why. Signing THINK with a blank face is understandable, but natural signing pairs the hand with an expression that fits the sentence. On camera, your face must be visible for this to work.

Do Deaf people think in sign language?

Many people who sign fluently, especially those who learned a sign language early, describe their inner thoughts as taking place partly or mainly in sign. Others describe thinking in a mix of signs, printed words, images or a spoken language. There is no single answer. A person's inner experience depends on when and how they learned their languages and how they use them day to day. No research figures were provided for this article, so it makes no claims about how common each experience is.

Check your signing on camera

Recording yourself is a practical way to verify the sign, and it also shows how you will look on a video call. Three separate things need to work, and one does not guarantee the next. Camera access means your browser or system has permission to use the camera. Successful capture means a live image or recording actually appears. Good quality means your hands and face are clear enough for someone else to read.

• Framing: show your head, shoulders and upper torso, with space above your head. THINK and THOUGHT happen at the forehead, so a crop at the eyebrows cuts off the sign.
• Lighting: light your face and hands from the front. A bright window behind you can turn you into a silhouette.
• Background: a plain physical background that contrasts with your skin and clothing makes handshapes easier to see.
• Virtual effects: background blur or replacement can blur, flicker or partly erase fast-moving hands. Turn the effect off and compare.
• Mirroring: many apps show your self-view as a mirror image, while other people may see the non-mirrored view. If your sign seems to be on the wrong side, check the recording rather than the live preview.
• Movement: sign at a natural pace, then play the clip back. If the circle for THOUGHT blurs into a smear, slow down slightly or add light.

Next step

Practice THINK as a single touch and THOUGHT as a small circle at the forehead. Record a short clip to check the handshape, location, movement and expression. Then confirm the forms with a Deaf signer or qualified instructor, especially if you are learning a sign language other than ASL.
