How To Sign By In Asl No Single Sign Exists?

There is no single sign in American Sign Language that means the English word “by.” The word “by” is a preposition, and ASL does not work like English. Instead of one sign, ASL uses a combination of signs, classifiers, and context to show the meaning of “by.” You choose the correct sign based on what the sentence actually means.

Why Is There No Single Sign for “By” in ASL?

ASL is not a word-for-word translation of English. It is its own language with its own grammar and sentence structure. English prepositions like “by,” “at,” and “with” do not have direct ASL equivalents because ASL builds meaning through spatial relationships and context.

Think about the many ways English uses “by.” You can say “the book by the bed,” “travel by car,” “written by the author,” or “by tomorrow.” Each of these uses a completely different meaning. In ASL, each of these sentences requires a different sign or structure. There is no single handshape that covers all of them.

This is a common frustration for new learners. You cannot look up “by” in an ASL dictionary and get one answer. The sign depends entirely on what the sentence is trying to say.

How Do You Sign “By” When It Means Location?

When “by” means “next to” or “beside,” you do not use a separate sign for “by” at all. Instead, you set up the objects in your signing space and use a classifier or a location sign.

For example, to say “the chair is by the table,” you would sign TABLE and CHAIR in their actual positions relative to each other. You establish where the table is, then show the chair next to it. The spatial placement itself communicates the meaning. This is how ASL naturally handles location without needing a preposition.

Alternatively, you can use the sign for BESIDE or NEXT-TO. This sign uses a flat hand that moves to the side of the other object. It is the closest single-sign equivalent, but it only works when “by” means physical proximity. It does not work for any other meaning of “by.”

How Do You Sign “By” When It Means Method or Transportation?

When “by” means “using” or “via,” as in “travel by car” or “pay by credit card,” you have a few options. The most common approach is to simply sign the method directly.

For “travel by car,” you sign CAR and then TRAVEL or DRIVE. The relationship is understood from context. You do not need a separate sign for “by.” The sentence structure in ASL makes the meaning clear without it.

For “pay by credit card,” you sign PAY and then CREDIT CARD. Again, the context carries the meaning. Some signers use the sign WITH in this situation, but that is not always accurate. The safest approach is to sign the sentence directly and let the verb and object make the relationship clear.

There is also a sign sometimes called BY-MEANS-OF, but it is not widely used in everyday conversation. It appears more in formal or educational settings. Most native signers simply drop the preposition and rely on word order.

How Do You Sign “By” When It Means the Author or Agent?

When “by” shows who did something, as in “a book by Stephen King,” ASL uses a different structure. You sign the book title or sign BOOK, then sign STEPHEN KING, then use the sign WRITE or AUTHOR. The order makes it clear that Stephen King is the author.

Some signers use a sign that means “written by” specifically. This sign involves a handshape that moves as if writing across a surface. But this is not a general sign for “by.” It only works for authorship.

For other actions, like “the painting by Van Gogh,” you sign PAINTING, then VAN GOGH, then PAINT. The verb tells the viewer who performed the action. ASL relies on this verb-first or agent-last structure instead of a preposition.

How Do You Sign “By” When It Means a Deadline?

When “by” means “before a certain time,” as in “finish by Friday,” ASL uses the sign for FINISH or DONE, followed by the day or time. You might also use the sign BEFORE if the deadline needs emphasis.

For example, “I need this by Friday” would be signed as NEED FINISH FRIDAY. The meaning is clear because the context establishes that Friday is the deadline. There is no need for a separate “by” sign.

If you want to emphasize that something must happen no later than a specific time, you can sign BEFORE FRIDAY or use the sign UNTIL. But again, this is not a translation of “by.” It is a different way of expressing the same idea using ASL grammar.

What About the Sign That Looks Like “By” in Some Dictionaries?

Some online dictionaries and apps show a sign for “by” that involves a bent hand moving past another hand. This is not a standard ASL sign used in everyday conversation. It is often a literal invented sign created by a dictionary or a sign that appears in very specific contexts.

You should be cautious with these sources. If you use that sign in a real conversation, a native signer may not understand what you mean. The sign may be technically listed somewhere, but it is not how deaf people actually communicate the idea of “by.”

This is a good example of why learning ASL from a dictionary alone does not work. You need to understand how the language structures meaning. The grammar and spatial use are more important than memorizing individual signs.

What Is the Best Way to Learn These Variations?

The best way to learn how to handle words like “by” is to study ASL sentence structure, not vocabulary lists. Focus on how native signers express location, method, agency, and time. Watch videos of deaf signers having real conversations. Pay attention to how they set up space and use context.

Practice by taking English sentences that use “by” and translating the meaning into ASL, not the words. Ask yourself what the sentence is actually saying. Is it about location? Method? Who did something? A deadline? Once you know the meaning, the correct ASL structure becomes clearer.

Working with a qualified ASL instructor or a deaf tutor is the most reliable path. They can correct your spatial use and show you how native signers express these ideas naturally. Online videos from deaf creators are also helpful because they show real usage in context.

There is no shortcut here. The word “by” is a perfect example of why ASL learners must think in concepts, not English words. Once you shift your thinking, these prepositions stop being confusing.
