The Spanish phrase for signing is “firma tu nombre,” with “firme su nombre” for polite or formal directions.
When a class handout, permission slip, worksheet, bank form, or ID card asks someone to sign, Spanish gives you more than one clean choice. The wording depends on who you’re speaking to, how formal the setting feels, and whether you mean a written signature or a printed name.
The safest daily-use phrase is firma tu nombre. It means “sign your name” when speaking to one familiar person, such as a child, classmate, or friend. In a school office, workplace, clinic, or any polite setting, use firme su nombre. That small change adds respect.
Saying Sign Your Name In Spanish With The Right Tone
Spanish commands change with the listener. English uses “you” for almost any listener, but Spanish separates friendly speech from polite speech. That’s why a teacher may say firma tu nombre to a student, while a receptionist may say firme su nombre to an adult visitor.
The verb behind both phrases is firmar, which means “to sign.” The word nombre means “name.” So the phrase is built from a command plus a possession word: tu for informal “your,” or su for polite “your.”
Use Firma Tu Nombre For Casual Speech
Firma tu nombre works well when the listener is a child, sibling, friend, teammate, or classmate. It sounds direct, plain, and natural. You might hear it when a teacher points to a worksheet line or a parent helps a child fill out a form.
Don’t write tú nombre in this phrase. The accent belongs to tú only when it means “you” as a subject. In tu nombre, the word means “your name,” so it has no accent.
Use Firme Su Nombre For Polite Or Formal Speech
Firme su nombre is the better choice with adults you don’t know well, customers, patients, officials, or anyone in a formal setting. It sounds courteous without feeling stiff.
This wording also works on written instructions, especially when one person must sign a paper. A form might say firme su nombre abajo, meaning “sign your name below.” It fits offices.
How To Say ‘Sign Your Name’ In Spanish On Forms
On forms, Spanish often favors compact directions. You may see firma, firma del solicitante, or nombre y firma. These don’t always translate word for word, but they tell the reader what to put in the blank.
For learner instructions, firma tu nombre aquí is clear and friendly. If you’re writing a formal document, firme su nombre aquí reads better. For a label near a blank line, firma alone is often enough because the line itself gives the context.
When Nombre Means Printed Name
One common mix-up is the difference between a name and a signature. Escriba su nombre means “write your name.” It usually asks for a printed name, not a signature. Firme su nombre asks for a signature.
Many forms need both. In that case, Spanish often uses nombre y firma, meaning “name and signature.” Put the printed name on the name line and the handwritten signature on the signature line.
A simple classroom rule helps here: firma points to the act of signing, while nombre points to the written name. If a form has both labels, each blank needs a different written response.
Choosing Tú, Usted, Or Ustedes
The right phrase depends on the pronoun behind “your.” Spanish has several choices, and the verb changes to match. You don’t have to name the pronoun each time, but the command form shows it.
Use tú when the tone is familiar. The command is firma. Use usted when the tone is polite. The command is firme. Use ustedes for more than one person. The command is firmen.
| Spanish Wording | Best Use | Plain Meaning |
|---|---|---|
| firma tu nombre | One familiar person | sign your name |
| firme su nombre | One polite or formal listener | sign your name |
| firma aquí | Casual spoken direction | sign here |
| firme aquí | Office, clinic, or service desk | sign here |
| ponga su firma | Formal written instruction | put your signature |
| escriba su nombre | Printed name line | write your name |
| nombre y firma | Form label with two required items | name and signature |
| firmen sus nombres | Group instruction | sign your names |
Commands For One Person
For one familiar listener, say firma tu nombre. This fits tutoring notes, classroom speech, family settings, and relaxed practice dialogues. It is direct, but not rude in casual relationships.
For one polite listener, say firme su nombre. Use this version for adults, clients, school staff, and public-facing instructions. It is the safer default when you’re unsure how formal to be.
Commands For More Than One Person
For a group, use firmen sus nombres. This means “sign your names.” It fits classroom directions such as “sign your names on the sign-in sheet.” You can also say firmen aquí if the place to sign is visible.
If you’re speaking in Spain, you may hear firmad vuestros nombres with a familiar group. Many learners outside Spain can stick with firmen sus nombres, since it is understood across Latin America and works in formal group settings too.
Pronunciation That Sounds Natural
English speakers often get close to Spanish pronunciation by keeping vowels clean. Say firma like FEER-mah, tu like too, and nombre like NOHM-breh. Keep the final e in nombre.
The r in firma is a light tap in many accents, not a heavy English “r.” The phrase is short: FEER-mah too NOHM-breh. Firme su nombre sounds like FEER-meh soo NOHM-breh.
| English Need | Spanish Phrase | Use It When |
|---|---|---|
| Please sign your name. | Por favor, firme su nombre. | A polite request to one person |
| Sign your name here. | Firma tu nombre aquí. | Casual direction with a visible line |
| Sign below. | Firme abajo. | A formal form instruction |
| Put your signature. | Ponga su firma. | A document label or official paper |
| Write your name. | Escriba su nombre. | A printed name field, not a signature |
Common Mistakes Learners Make
A common mistake is translating “sign” as señal. That word means a sign, signal, or signboard, not signing a document. For documents, use firmar as the verb and firma as the noun.
Another mistake is using signar. The verb exists in Spanish, but it is not the normal word for signing daily paperwork. In school, travel, business, and service settings, firmar is the word you want.
Learners may confuse firma as a command with firma as a noun. In firma tu nombre, firma means “sign.” In la firma, it means “the signature.” Context makes the meaning clear.
Do You Need Nombre Each Time?
No. If the signing line is visible, Spanish speakers often say firma aquí or firme aquí. Adding tu nombre or su nombre helps when teaching the phrase or making the request explicit.
On an official form, firma may appear by itself. That single word tells readers to sign. If the form asks for a printed name too, it may show nombre on one line and firma on another.
Classroom And Real-Life Practice Lines
Practice with full sentences so the phrase feels usable, not memorized. A teacher might say, Firma tu nombre al inicio de la hoja, meaning “sign your name at the top of the page.” A clerk might say, Firme su nombre en la línea, meaning “sign your name on the line.”
For a permission slip, you might write Padre, madre o tutor: firme su nombre abajo. That means “Parent or guardian: sign your name below.” For a sign-in sheet, a teacher could say Firmen sus nombres antes de sentarse, meaning “sign your names before sitting down.”
For a relaxed message to a friend, firma aquí is enough. For an email asking someone to return a document, write Por favor, firme su nombre y devuelva el formulario. That means “Please sign your name and return the form.”
Best Phrase To Use Most Of The Time
If you’re speaking to a friend, student, child, or classmate, say firma tu nombre. If you’re speaking to an adult in a formal setting, say firme su nombre. If you’re writing a label on a form, firma or nombre y firma may be cleaner.
The easiest safe pattern is this: use firma tu nombre for friendly speech, firme su nombre for polite speech, and firmen sus nombres for groups. Those three forms will handle most school, office, travel, and document situations without sounding odd.
