Writing Sign Language Dialogue: A Practical Guide

The short answer: in most stories and articles, write signed dialogue as fluent, natural English and tell the reader it is signed, using a tag such as "she signed" or a consistent format like italics. Save word-by-word notation, called gloss, for linguistic transcription, teaching materials or cases where the structure of the sign language itself matters. Sign languages such as American Sign Language (ASL) are complete languages with their own grammar, not English spelled out with the hands, so a choppy literal rendering usually misrepresents the speaker rather than adding authenticity.

First, decide what kind of text you are writing

"Writing sign language dialogue" can mean several different tasks, and the right method depends on which one you mean:

• Fiction or narrative nonfiction: you want readers to follow a conversation smoothly. Translate into natural English and mark it as signed.
• Screenplays and stage scripts: you need to tell actors and the production team which lines are signed and how the audience will understand them, such as through subtitles or an interpreter.
• Linguistic transcription or teaching: you need to show the sign language's own word order, grammar and facial markers. Use gloss.
• Notes or a written record of a signed video call: you usually want the meaning, written as an English translation, possibly with a note that it was interpreted or translated.

Writing signed dialogue in fiction

• 1. Translate meaning, not individual signs. Give a signing character the same fluency, humor and vocabulary you would give a speaking character.
• 2. Choose one way to mark signed speech and use it consistently. Common options are dialogue tags ("he signed"), italics, or a distinct quotation style explained early in the text.
• 3. Show the physical channel where it matters to the scene. Facial expressions, eye gaze, sign size and speed carry meaning in sign languages, so describe them when they affect tone, much as you would describe a shouted or whispered line.
• 4. Account for sight lines. Signed conversation depends on seeing each other, so think about lighting, distance, turned backs and full hands when staging the scene.
• 5. Handle mixed conversations clearly. If one character signs and another speaks, or an interpreter is present, make it obvious who is communicating in which way.
• 6. Name the sign language if it is relevant, for example ASL in the US. Sign languages differ by country and are not mutually intelligible by default.

Maya caught his eye across the kitchen and signed, "You forgot the keys again, didn't you?"

Her eyebrows went up and stayed there.

"I didn't forget," Leo signed back, too quickly. "I'm testing your memory."

Writing signed lines in a script

In scripts, the aim is clarity for the people producing the work. A common approach is to write the English meaning of the line and add a parenthetical or a note indicating that it is signed and how the audience receives it, for example whether it is subtitled, voiced by another character or left untranslated on purpose. Formatting conventions differ between productions and script tools, so follow the style guide you have been given if one exists.

MAYA
(in ASL, subtitled)
You forgot the keys again, didn't you?

Using gloss for transcription

Gloss writes each sign with an English word, traditionally in capital letters, in the order the signs are produced. It is a notation for analysis, not a translation, and it does not capture handshapes or movement. Conventions vary between textbooks, researchers and sign languages, but the following are widely used for ASL:

Convention | Meaning

CAPITAL WORDS | Each word represents one sign, e.g. STORE

Hyphenated words | One sign that needs several English words, e.g. DON'T-KNOW

Letters separated by hyphens, or a prefix such as fs- | Fingerspelling, e.g. J-O-H-N or fs-JOHN

IX | Pointing (index) to a person, place or thing

++ after a gloss | The sign is repeated

Label over or before a phrase, such as q, wh-q or neg | Facial or head markers, such as raised eyebrows for a yes/no question

Gloss:        STORE IX-loc, YOU GO FINISH?
Marker:       (raised eyebrows over the question, q)
Translation:  Did you already go to the store?

When you use gloss, always pair it with an English translation so readers who do not know the notation can follow the meaning. More detailed systems exist for representing the form of signs themselves, such as SignWriting, HamNoSys and Stokoe notation, but these are specialist tools and are rarely needed outside linguistics or sign language teaching.

Check your result

• Can a reader always tell which lines are signed and which are spoken?
• Is your marking method the same throughout the text?
• Does the signing character sound as fluent as the speaking characters, unless their language skill is a deliberate part of the story?
• If you used gloss, did you explain the conventions and include a translation?
• Did you name or make clear which sign language is being used when it matters?
• Has someone fluent in that sign language, ideally a Deaf reader, reviewed the signed passages?

Limitations and gaps

There is no single official standard for writing signed dialogue: publishers, script formats, textbooks and researchers use different conventions, and those for ASL do not automatically apply to other sign languages such as Russian Sign Language or British Sign Language. No specific style guides, studies or reader surveys were available for this guide, so the conventions above are general practice rather than rules from a cited authority. If your work depends heavily on signed communication, the most reliable next step is to consult fluent signers or Deaf sensitivity readers and to check the style requirements of your publisher, production or course.
