Understanding Spanish Ordinal Numbers

This lesson covers ordinal numbers in Spanish, which are used to express the position or order of items in a sequence, such as first, second, third, and so on. These are essential for everyday conversations, whether giving directions, organizing events, or describing a sequence of events.

Basic Ordinal Numbers (1st to 10th)

The first ten ordinal numbers are:

NumberMasculineFeminine
1º / 1ªPrimeroPrimera
2º / 2ªSegundoSegunda
3º / 3ªTerceroTercera
4º / 4ªCuartoCuarta
5º / 5ªQuintoQuinta
6º / 6ªSextoSexta
7º / 7ªSéptimoSéptima
8º / 8ªOctavoOctava
9º / 9ªNovenoNovena
10º / 10ªDécimoDécima

Gender and Agreement

Ordinal numbers must agree in gender and number with the noun they describe. Masculine forms are used with masculine nouns, and feminine forms with feminine nouns.

For example:

  • El cuarto capedtulo es muy interesante. (The fourth chapter is very interesting.)
  • Ella vive en el primer piso de este edificio. (She lives on the first floor of this building.)

Special Cases

The ordinal numbers primero and tercero lose the final "o" when they appear before masculine singular nouns, becoming primer and tercer respectively.

Example sentences include:

  • El primer día de la semana es lunes.
  • El tercer estudiante llegó tarde.

Use Beyond Ten

For ordinal numbers higher than ten, Spanish speakers commonly prefer to use cardinal numbers instead of formal ordinal forms.

Key Takeaways

  • Ordinal numbers indicate order or position in a sequence.
  • They agree in gender and number with the noun they modify.
  • Primero and tercero have a special form before masculine singular nouns.
  • Numbers above ten are typically expressed with cardinals.

Notes on Differences from English

In Spanish, ordinal numbers must match the gender of the noun (masculine or feminine). In English, ordinal numbers like "first," "second," and "third" do not change according to gender. Also, Spanish ordinal numbers can change form slightly depending on their position in a sentence, like primeroprimer before masculine singular nouns, a feature not present in English.

Useful Phrases

  • Primero / Primera — First
  • Segundo / Segunda — Second
  • Tercer / Tercero / Tercera — Third
  • Cuarto / Cuarta — Fourth
  • Quinto / Quinta — Fifth

Example: Ella llegó en primer lugar. (She arrived in first place.)
