How To Sign Big In ASL: The Definitive Guide To American Sign Language Size Modifiers

To sign "big" in ASL, form both hands into modified "L" or "C" handshapes with palms facing each other, start with your hands close together in the center of your chest, and pull them outward horizontally. To accurately convey scale, you must pair this movement with specific non-manual signals (NMS) such as the "cha" mouth morpheme for immense size or puffed cheeks for thick volume. Mastering these linguistic parameters ensures your signing clearly distinguishes between a standard large object and a colossal entity.

Mastering the ASL Signing Space and Five Linguistic Parameters

In American Sign Language (ASL), vocabulary is not merely about hand shapes; it is a highly structured 3D linguistic system. To sign "big" correctly, you must operate within your natural signing space—the box extending from the crown of your head to your waist, and from shoulder to shoulder. Within this space, every sign is governed by five primary phonological parameters: handshape, location, movement, orientation, and non-manual signals (NMS). Adjusting any one of these parameters changes the meaning, intensity, or context of the sign.

To prepare for expressive signing, you must train your muscles to maintain precise physical boundaries while utilizing your face as a grammatical tool. Unlike spoken languages where volume is controlled by vocal cords, volume and scale in ASL are controlled by physical tension, speed, spatial range, and facial expressions.

Technical Preparation and Baseline Requirements

• Essential Gear and Feedback Tools: Use a high-definition video camera (such as a smartphone or webcam) positioned at chest height, a full-length or torso-view mirror for real-time visual alignment, and neutral background lighting to prevent hand shadows from obscuring your facial expressions.
• Mandatory Prerequisite Knowledge: You must understand the concept of "neutral space" (the area directly in front of your chest where non-contact signs are executed) and the role of mouth morphemes, which function as mandatory adjectives in ASL grammar.
• Physical Benchmarks and Drills: Dedicate 15 minutes to finger, wrist, and shoulder stretching. Practice isolating your facial muscles—specifically your eyes, cheeks, and lips—independent of your hand movements.

Step-by-Step Execution: How to Sign and Inflect "BIG"

To execute the sign for "BIG" (and its various degrees of scale) with native-level accuracy, follow these steps. This process breaks down the lexical sign and explains how to inflect it for varying degrees of size.

Step 1: Establish the Correct Handshape and Orientation

Begin by raising both hands into your signing space. Form both hands into modified "L" handshapes. To do this, extend your thumbs and index fingers at a 90-degree angle, while curling your middle, ring, and pinky fingers tightly into your palms.

Your palms must face each other (medial orientation) with your knuckles pointing forward toward your conversational partner. Your index fingers should point upward and slightly outward, resembling two backward "L"s facing one another.

Step 2: Set the Starting Location in Neutral Space

Position your hands in the center of your signing space, directly in front of your chest. Your hands should be parallel, separated by a distance of approximately 4 to 6 inches. Ensure your elbows are bent naturally at your sides, keeping your shoulders relaxed to avoid looking stiff. This close starting position is crucial because it establishes the baseline from which you will measure the outward movement.

Warning: Do not let your hands touch at the start of this sign. Keeping a clear 4-to-6-inch gap prevents confusion with signs like "MEET" or "LIMIT."

Step 3: Execute the Outward Horizontal Movement

Pull both hands horizontally outward, away from each other, along a straight plane. Keep your hands level; do not let them drift upward or downward during the movement.

As your hands travel outward, make a slight, sharp outward arc with your wrists to emphasize the final boundary of the object. For a standard representation of "big," stop your hands when they reach just past the width of your shoulders (a total travel distance of about 18 to 24 inches).

Pro-Tip: The speed and tension of your movement dictate the intensity of the sign. A slow, steady pull indicates a large, steady presence, while a rapid, sudden snap outward indicates a startlingly large size.

Step 4: Apply the Mandatory Non-Manual Signals (NMS)

Your hands only convey half the message; your face must provide the grammatical modifier. As your hands move outward, open your eyes wider than normal. Simultaneously, form your mouth into the "cha" morpheme by opening your mouth slightly, pulling your lips back to expose your teeth, and silently voicing the syllable "cha" (without using your vocal cords).

This facial gesture is the linguistic equivalent of adding the adjective "huge" or "enormous" to a noun.

Step 5: Transition to Classifiers for Specific Spatial Contexts

If you are describing a specific object rather than using the generic word "big," transition your handshapes into Classifiers (CL). Classifiers are handshapes used to represent the size, shape, and path of an object.

To sign a big ball, use clawed "5" handshapes (CL:C or CL:5) to outline the spherical shape in front of you. To sign a big building, use flat "B" handshapes to trace the massive vertical and horizontal walls. Always match your facial NMS to the physical dimensions you are tracing with your classifiers.

Common Linguistic Errors and Practical Remedies

To ensure your ASL is natural and grammatically correct, avoid these common performance errors.

The "Flat Expression" Error (Lack of NMS)

• Root Cause: Beginners often focus entirely on their hands, leaving their face expressionless or "deadpan." In ASL, signing "BIG" with a flat face is a grammatical contradiction, equivalent to saying "that is a very small big house."
• Actionable Fix: Practice signing in front of a mirror with your hands held behind your back. Practice the "cha" mouth shape and eye-widening gestures until they feel natural. Once comfortable, reintroduce the hand movements, ensuring your facial muscles activate at the exact moment your hands begin to move outward.

Overextending the Signing Space (The "Wild Arms" Error)

• Root Cause: To show that something is exceptionally large, learners often swing their arms wildly outside their comfortable reach, causing them to lose physical balance and break the visual flow of the conversation.
• Actionable Fix: Keep your elbows anchored near your ribcage. Instead of reaching far outward to show extreme size, increase the physical tension in your arm muscles and use a dramatic, slow-motion movement combined with a more intense facial expression. Intensity is conveyed through muscle tension and facial grammar, not by overextending your joints.

Handshape Collapse (Losing the "L" Profile)

• Root Cause: During the outward movement, the thumb and index finger often droop or fold toward the palm, turning the modified "L" into a closed "G" or an indistinct flat hand.
• Actionable Fix: Focus on maintaining isometric tension between your thumb and index finger. Keep your wrists locked at a 90-degree angle relative to your forearms throughout the entire horizontal path. Your fingers must remain rigid until the sign is fully completed and your hands return to a resting position.

Frequently Asked Questions

What is the difference between signing "big" and "large" in ASL?

In ASL, "big" and "large" share the same conceptual sign (the outward-moving "L" handshapes). The difference lies entirely in your context and non-manual signals. "Large" is often signed with a smoother, wider sweep, while "big" can be signed with more abrupt, sharp movements depending on the specific object you are describing.

How do you sign "very big" or "gigantic" in ASL?

To sign "very big" or "gigantic," you must intensify the physical delivery of the sign. Tense your arm muscles, widen your eyes, tilt your head slightly back, and pull your hands far past your shoulders with a heavy, deliberate movement. You must also pair this movement with a pronounced "cha" mouth morpheme.

Can you use classifiers instead of the lexical sign for "BIG"?

Yes, fluent ASL signers often prefer classifiers over the lexical sign for "BIG." Instead of signing "DOG BIG," a fluent signer will sign "DOG," and then use classifiers (such as showing the height of the dog's back with a flat hand or the thickness of its body with "C" handshapes) to show exactly how the dog is big.

Why is facial expression so important when signing "big"?

Facial expressions, or non-manual signals (NMS), are a fundamental part of ASL grammar. Without NMS, the sign for "big" lacks clear descriptive value. Your face acts as the adjective or adverb, telling the viewer whether the object is moderately big, incredibly tall, thick, or towering.
