Spanish Ordinal Numbers For Beginners

Learn first, second, third, and the rest without memorizing a weird grammar jungle you will barely use.

The first time I checked into a small hotel in Mexico City, I understood every number right up until the receptionist smiled and said, “Su habitación está en el tercer piso.” I knew tres. I did not know tercer. So I nodded with false confidence, walked toward the wrong elevator, and immediately learned that knowing numbers is not the same as knowing the order of things. Spanish loves that distinction. Very rude. Very useful.

That is exactly what Spanish ordinal numbers do: they tell you the position of something in a series. In this guide, you will learn the forms you will actually hear, the rules that matter, the mistakes beginners make, and the real-life phrases that show up in offices, apartments, meetings, contracts, and everyday conversation.

Yak Box: The Quick Truth

You really need 1st to 10th first. Those are the workhorses.
Spanish ordinal numbers usually go before the noun: la segunda reunión.
They must match the noun in gender and number: primer pago, primera llamada, primeros días.
After 10th, everyday Spanish often switches to a cardinal number: el piso veinte instead of el vigésimo piso.

Spanish Ordinal Numbers 1 To 10

These are the forms you will actually use the most. Learn them well, because higher ordinal numbers exist, but everyday Spanish gets a lot less enthusiastic about using them.

Spanish	English Meaning	Example In Spanish	English Translation
primero / primer	first	Hoy es mi primer día en la oficina.	Today is my first day at the office.
segundo	second	Vivo en el segundo piso.	I live on the second floor.
tercero / tercer	third	Esta es tu tercera opción.	This is your third option.
cuarto	fourth	La reunión es en el cuarto salón.	The meeting is in the fourth room.
quinto	fifth	Es la quinta vez que cambian la fecha.	It is the fifth time they have changed the date.
sexto	sixth	Estamos en el sexto mes del proyecto.	We are in the sixth month of the project.
séptimo	seventh	Su oficina está en el séptimo edificio.	His office is in the seventh building.
octavo	eighth	Revisa la octava cláusula del contrato.	Check the eighth clause of the contract.
noveno	ninth	Vamos por el noveno capítulo del curso.	We are on the ninth chapter of the course.
décimo	tenth	Celebran su décimo aniversario este año.	They are celebrating their tenth anniversary this year.

How Spanish Ordinal Numbers Behave

Spanish ordinal numbers act like adjectives, so they agree with the noun they describe. That means the ending changes depending on whether the noun is masculine, feminine, singular, or plural. Yes, the number has homework too.

Pattern	Meaning	Example
el primer pago	masculine singular	Mi primer pago llega el viernes. — My first payment arrives on Friday.
la primera reunión	feminine singular	La primera reunión empieza a las nueve. — The first meeting starts at nine.
los primeros días	masculine plural	Los primeros días fueron intensos. — The first days were intense.
las primeras semanas	feminine plural	Las primeras semanas pasan rápido. — The first weeks go by fast.

Usual Position

Most of the time, the ordinal comes before the noun.

la segunda cita — the second date / appointment
el tercer intento — the third attempt
la cuarta llamada — the fourth call

Real-Life Usage

After tenth, everyday Spanish often prefers a cardinal number after the noun.

el piso veinte — the twentieth floor
el capítulo once — the eleventh chapter
la página treinta — the thirtieth page

The Two Changes That Trip Beginners Up

Primero And Tercero Get Shorter

Before a singular masculine noun, primero becomes primer and tercero becomes tercer.

primer piso — first floor — La oficina está en el primer piso.
primer pago — first payment — Mi primer pago vence mañana.
tercer intento — third attempt — Fue mi tercer intento hoy.
tercer día — third day — Hoy es el tercer día del evento.

But when the noun is feminine, keep the full form: primera llamada, tercera semana.

How The Abbreviations Work

You will often see ordinal numbers written with a numeral plus a small letter. These are common in dates, lists, titles, contests, and formal writing.

Form	English Meaning	Example
1.º	first, masculine	el 1.º premio — the first prize
1.er	first, shortened before masculine noun	el 1.er día — the first day
1.ª	first, feminine	la 1.ª vez — the first time
3.er	third, shortened before masculine noun	el 3.er piso — the third floor

After Tenth: What You Need To Recognize

You do not need to use high ordinal numbers all day long to sound natural. You mostly need to recognize them, especially in writing, formal speech, titles, anniversaries, and rankings.

The two most important extra forms are these: undécimo or decimoprimero for eleventh, and duodécimo or decimosegundo for twelfth. Both pairs are correct. In normal life, many speakers still prefer a cardinal after the noun: capítulo once, piso doce.

Spanish	English Meaning	Example
undécimo / decimoprimero	eleventh	El undécimo capítulo es corto. — The eleventh chapter is short.
duodécimo / decimosegundo	twelfth	Es su duodécimo aniversario. — It is their twelfth anniversary.
decimotercero	thirteenth	El decimotercer piso está cerrado. — The thirteenth floor is closed.
vigésimo	twentieth	Celebran el vigésimo aniversario de la empresa. — They are celebrating the company’s twentieth anniversary.
vigésimo primero / vigesimoprimero	twenty-first	Hoy es mi vigésimo primer día aquí. — Today is my twenty-first day here.
trigésimo primero	thirty-first	Terminó en el trigésimo primer lugar. — He finished in thirty-first place.
centésimo	hundredth	Esa fue la centésima llamada de la semana. — That was the hundredth call of the week.

One more useful warning: onceavo and doceavo are usually fractional forms, not ordinal ones. So for “eleventh floor,” go with undécimo piso or, more naturally in everyday speech, piso once.

Useful Real-Life Phrases

These are the kinds of chunks you can actually steal for real conversation. Much better than staring at a 1-to-100 list and pretending that helped.

primer pago — first payment
Mi primer pago llega el viernes.

segunda cita — second date / appointment
Tuvimos una segunda cita el sábado.

tercer piso — third floor
La oficina está en el tercer piso.

cuarta llamada — fourth call
No contestó la cuarta llamada.

quinta vez — fifth time
Es la quinta vez que me piden ese documento.

sexto mes — sixth month
Ya estamos en el sexto mes del proyecto.

séptimo asiento — seventh seat
Su boleto es para el séptimo asiento.

octava cláusula — eighth clause
La octava cláusula habla de pagos.

noveno capítulo — ninth chapter
El noveno capítulo resume todo.

décimo aniversario — tenth anniversary
Celebran su décimo aniversario en julio.

A Tiny Date Note That Matters

In Mexico and much of Latin America, the first day of the month is usually expressed with primero: primero de mayo, primero de enero. After that, dates normally use cardinal numbers: dos de mayo, quince de enero.

Common Mistakes And Fast Fixes

primero piso ❌ → primer piso ✅
Use the short form before a singular masculine noun.
tercero intento ❌ → tercer intento ✅
Same rule. Spanish is consistent here, which is suspicious but helpful.
la segundo reunión ❌ → la segunda reunión ✅
The ordinal has to match the feminine noun.
el onceavo piso ❌ → el undécimo piso ✅
Or, in everyday speech, just say el piso once.
el vigésimo piso everywhere, every time ❌ → sometimes el piso veinte ✅
Formal ordinals exist, but everyday Spanish often prefers the simpler version after tenth.

Practice Section

Try these before peeking at the answers. Your brain deserves at least one honest attempt.
