ASL Numbers and Time Expressions

Mastering numbers and time in American Sign Language is about far more than memorizing handshapes; it's about unlocking fluid, efficient daily conversation. Whether you're scheduling a meeting, sharing your age, discussing prices, or recounting a story with specific details, these signs form the essential numerical backbone of ASL. This guide will build your proficiency from foundational cardinal numbers to the nuanced incorporation of numbers into other signs, focusing on the clarity and cultural conventions that define natural signing.

Foundational Number Systems: Cardinal and Ordinal

The bedrock of numerical expression in ASL is the cardinal number system—the signs for counting and stating quantities (1, 2, 3, etc.). These signs are produced with specific handshapes, palm orientations, and sometimes movements. The numbers 1 through 5 are typically shown with the palm facing the signer, while 6 through 10 have distinct, often iconic, handshapes. Numbers in the teens (11-15) often incorporate a small twisting or bouncing movement from the base number sign.

A critical point of confusion for many learners is the similar handshapes for 6 and 9, and for 7 and 8. The number 6 is signed with the thumb touching the pinky, while 9 is signed with the thumb touching the index finger. For 7, the thumb touches the middle finger, and for 8, it touches the ring finger. Consistent, clear formation here prevents major misunderstandings.

Moving beyond simple quantities, ordinal numbers indicate position or order (1st, 2nd, 3rd). In ASL, you generally form the cardinal number and then twist your wrist so the palm faces outward, away from your body. For example, to sign "third," you would sign the number 3 and then twist your wrist forward. This simple transformation is applied across the number system to create order from quantity.

Expressing Time: From Hours to Calendar Dates

Time concepts in ASL are often signed in relation to an imaginary timeline that runs across your body. The space directly in front of you represents "now." The future is signed forward along this line, and the past is signed backward over your shoulder. To sign a specific hour, like "3 o'clock," you would sign the number 3 and then tap the top of your non-dominant wrist, where a watch would be.

For durations and more complex time expressions, numbers incorporate directly into time signs. The sign for "week" is made by drawing the index finger of your dominant hand across the palm of your non-dominant hand. To sign "two weeks," you use a "2" handshape to perform that same movement. This principle of number incorporation—modifying a base sign with a specific number handshape—is a key efficiency tool in ASL. You see it in signs like "three months," "five minutes," and "ten years."

Calendar dates follow a logical sequence. You typically sign the number for the day, then the month, and finally the year, often fingercelling each digit of the year (e.g., 2-0-2-5). When discussing ages, the number sign moves slightly away from the body in a small arc, starting near the chin. The movement itself conveys the concept of age, so you don't need to add a separate sign for "years old."

Monetary Amounts and Numerical Quantifiers

Discussing money is a practical application of number skills. For whole dollar amounts, you sign the number and then follow it with the sign for DOLLAR (extending the dominant hand forward as if offering paper currency). For cents, you sign the number and then the sign for CENTS (the index finger touching the forehead and moving forward). For mixed amounts like $4.75, you would sign 4-DOLLAR, then 75-CENTS.

Beyond specific prices, numbers are used as quantifiers with other nouns. To sign "three people," you would sign THREE and then PEOPLE. However, for some signs, the number is incorporated. A classic example is the sign for "hours," where the number handshape (like a "2" for two hours) circles in front of a clock face indicated by the non-dominant hand. Recognizing which signs allow for incorporation and which require a separate number sign comes with exposure and practice.

This system also extends to approximations. To sign "about 20," you would sign the number 20 but with loose, repeated movement. For "more than 100," you sign 100 and then use a facial expression and movement indicating excess. These nuanced uses move you from robotic signing to expressive communication.

The Efficiency of Number Incorporation

Number incorporation is a grammatical feature that makes ASL visually efficient and fluid. It involves merging a number handshape directly into the movement or location of another sign. This isn't used arbitrarily; it applies to a set of specific concepts, primarily time, age, money, and pluralized countable nouns.

For example, the sign for "week" is a base. To sign "four weeks," you use a "4" handshape to execute the same movement. The sign for "month" (index finger tracing the outline of the moon) becomes "three months" with a "3" handshape. This incorporation eliminates the need to sign the number separately, creating a more cohesive and faster signed utterance.

Mastery of this technique requires knowing which concepts allow it. While you can incorporate numbers into TIME, WEEK, MONTH, YEAR, HOUR, MINUTE, DOLLAR, and AGE, you generally cannot incorporate them directly into signs for objects like "book" or "car." For those, you would sign the number separately (THREE BOOK). Learning this distinction is crucial for grammatical accuracy.

Common Pitfalls

1. Inconsistent Palm Orientation for Cardinal Numbers: A frequent error is mixing up the palm orientation for numbers 1-5 (palm in) versus numbers 6-10 (palm typically angled toward the listener or down). This can blur the distinction between numbers. Consciously practice the standard orientations to build muscle memory.
2. Confusing 6/9 and 7/8: As mentioned, these pairs are often muddled. A helpful tip is to remember the sequence: 6 (thumb to pinky), 7 (thumb to middle finger), 8 (thumb to ring finger), 9 (thumb to index finger). Slow, deliberate practice of this sequence builds clarity.
3. Over-Incorporating Numbers: Learners sometimes try to force number incorporation into signs that don't allow it, like signing "three cars" by using a "3" handshape on the vehicle classifier. This is incorrect. The number should be signed separately before the noun or classifier.
4. Neglecting Non-Manual Signals for Time: When signing about the past or future, your facial expression and body lean are vital. Discussing "last year" requires a look back over your shoulder and a past-tense facial marker. Omitting these makes your timeline expressions feel flat and less clear.

Summary

• ASL numbers require precise handshapes, movements, and palm orientations, with special attention needed to distinguish between similar numbers like 6/9 and 7/8.
• Time expressions operate along a spatial timeline and frequently use number incorporation for efficiency, as seen in signs for weeks, months, hours, and ages.
• Monetary amounts follow a clear pattern: number + DOLLAR and/or number + CENTS, while other quantifiers may or may not allow incorporation.
• Number incorporation is a key grammatical feature that blends a number handshape directly into signs for specific concepts like time and money, but it is not used for all plural nouns.
• Achieving fluency with numbers and time involves mastering both the manual signs and the accompanying non-manual signals, such as facial expressions and body shifts, to convey tense and nuance accurately.
