Welcome to our post about Ordinal Numbers in Spanish (Números Ordinales).

We will go through these points:

  • 1. What are Ordinal Numbers?
  • 2. List of Ordinal Numbers
  • 3. Feminine and Plural forms
  • 4. Short Forms of “primero” and “tercero”



1. What are Ordinal Numbers?

An Ordinal Number expresses the order (first, second, third…) of a noun within a series or sequence. For example, If someone says “this is my first coffee of the day”, that is the first coffee of a series or coffees still to come 🙂

Basically then, in this post we will learn the equivalent of the English words “first, second, third, fourth”, etc. If you arrived at this post by mistake, and what you wanted to learn were the cardinal numbers (one, two, three…), click here for our post about cardinal numbers.

 

2. List of Ordinal Numbers

From 1 to 10:

These ones you have to just learn them 🙂

1stprimero
2ndsegundo
3rdtercero
4thcuarto
5thquinto
6thsexto
7thséptimo
8thoctavo
9thnoveno
10thdécimo

From 11 to 19:

Still written in just one word, consisting on “décimo-” followed by the words learned in the previous table (but 18th = decimoctavo, not “decimooctavo”)

11thdecimoprimero (or "undécimo")
12thdecimosegundo (or "duodécimo")
13thdecimotercero
14thdecimocuarto
15thdecimoquinto
16thdecimosexto
17thdecimoséptimo
18thdecimoctavo
19thdecimonoveno

From 20 to 99:

You need to learn each of the tens (30, 40, 50…). Then, if the number also has units, you write two separate words: one for the tens and one for the units (using the words in the first table of this post):

20thvigésimo
21stvigésimo primero
27thvigésimo séptimo
30thtrigésimo
33rdtrigésimo tercero
38thtrigésimo octavo
40thcuadragésimo
45thcuadragésimo quinto
50thquincuagésimo
60thsexagésimo
70thseptuagésimo
80thoctogésimo
90thnonagésimo
99thnonagésimo noveno

From 100 to 1000:

You need to learn each of the hundreds (100, 200, 300…) and again, keep adding words if there are tens and units, using the previous tables.

100thcentésimo
113rdcentésimo decimotercero
185thcentésimo octogésimo quinto
200thducentésimo
220thducentésimo vigésimo
296thducentésimo nonagésimo sexto
300thtricentésimo
381sttricentésimo octogésimo primero
400thcuadringentésimo
500thquingentésimo
600thsexcentésimo
700thseptingentésimo
800thoctingentésimo
900thnoningentésimo
999thnoningentésimo nonagésimo noveno
1000milésimo

 

3. Feminine and Plural forms

As it’s typical in Spanish, you need to match the gender and number of the ordinal number to the noun it refers to.

If the ordinal number consists on more than one word, you match the number of the gender of each of the words, not just the last one. Some examples:

 Singular MasculinePlural MasculineSingular FemininePlural Feminine
2ndsegundosegundossegundasegundas
17thdecimoséptimodecimoséptimosdecimoséptimadecimoséptimas
39thtrigésimo novenotrigésimos novenostrigésima novenatrigésimas novenas
225thducentésimo vigésimo quintoducentésimos vigésimos quintosducentésima vigésima quintaducentésimas vigésimas quintas

 

4. Short Forms “primer” and “tercer”

For any ordinal number that includes the words “primero” or “tercero” (including “decimoprimero” and “decimotercero”) there is also a shorter form: “primer”, “tercer”, “decimoprimer” and “decimotercer”.

We will use this shorter form ONLY for the masculine singular case, and ONLY when the ordinal number comes right before the noun it refers to.
