The Definitive Guide to Ordinal Numbers in Spanish – Primero (1st), Segundo (2nd)…

The Definitive Guide to ORDINAL NUMBERS in Spanish (Primero,...) 1️⃣

You probably know by now how to count in Spanish (if not check out my video about the Spanish numbers), but the question is now how do you say first, second third, and so on in Spanish? This is where los números ordinales (ordinal numbers in Spanish) come into play!

In this article, you will find out how ordinal numbers work and how to use them in Spanish! 

1. What are ordinal numbers in Spanish?

Los números ordinales (ordinal numbers in Spanish) are the ones we know as first, second, third and so on. These could be seen as the adjective form of cardinal numbers, where one is first, two is second, and three is third… well, you get the idea.

The first ten ordinal numbers are the most common and most important and they usually go accompanied by a noun because, as we said before, they are used as an adjective.

Additionally, ordinal numbers in Spanish must agree with the noun gender we are referring to.

2. How to use ordinal numbers: gender agreement

I will teach you the first 10 ordinal numbers using an example in feminine and masculine. That way, you will learn new vocabulary while learning the ordinal numbers!


When the noun is masculine, letter O should be taken out: el primer rey (the first king), and when the noun is feminine, you should use an A instead: la primera vez (the first time).


  • El segundo hermano (The second brother)
  • La segunda hija (The second daughter)


  • El tercer amigo (The third friend)
  • La tercera oportunidad (The third opportunity)

Same as FIRST, in the last O should be removed when the noun is masculine.


  • El cuarto piso (The fourth floor)
  • La cuarta salida (The fourth exit)


  • El quinto libro (The fifth book)
  • La quinta estación (The fifth station)


  • El sexto gol (The sixth goal)
  • La sexta jugada (The sixth move)


  • El séptimo pecado (The seventh sin)
  • La séptima ocasión (The seventh occasion)


  • El octavo pasajero (The eighth passenger)
  • La octava película (The eighth movie)


  • El noveno día (The ninth day)
  • La novena niña (The ninth girl)


  • El décimo grado (The tenth grade)
  • La décima nota (The tenth note)

3. Learn Spanish sentences with ordinal number vocabulary

Fun fact: if ordinal numbers are used in a statement where the noun is already implied, then you must use the original form.

So let’s see some examples with the following chunks used in Spanish:

  • ¡Salud por el primero de muchos! (Cheers for the first of many more to come!)
  • La tercera es la vencida. (The third time is the charm.)
  • De mis perros, el segundo es el más travieso. (From my dogs, the second is the most naughty.) 
  • El atleta llegó cuarto. (The athlete arrived in fourth.)

Second fun fact: if you need to use ordinal numbers in plural, then you must add an S at the end of each number. For example:

  • Los primeros carros (The first cars)
  • Las segundas veces (The second times)

I have been so insistent in learning the different ways to use first to tenth in Spanish because we rarely use ordinal numbers from 11th onwards. The reason is that, unlike English, where statements like “It’s her 30th birthday” are common, Spanish would rather say:

Es su cumpleaños número treinta or es su 30 aniversario.

Similarly, although English speakers say “20th Century”, Spanish speakers say “siglo veinte“.

But just so you know, if you must use ordinal numbers from 13th onwards, it would be better for you to learn the numbers in ten, as every ordinal number in between you will just add the name that we just learned…

Let’s start by:

décimo – vigésimo- trigésimo- cuadragésimo – quincuagésimo – sexagésimo – septuagésimo – octogésimo- nonagésimo

And in between as I said just to give you a few examples would sound like this:

  • 13 – décimo tercero
  • 89 – octogésimo noveno
  • 75 – septuagésimo quinto 
  • 67 – sexagésimo séptimo
  • 58 – quincuagésimo octavo

And to finish today’s lesson, here’s 11th and 12th in Spanish:

  • 11 – undecimo
  • 12 – duodecimo
