Introduction

Numbers [números] can be represented by digits or words and generally express quantity (cardinal numbers) or order in a sequence (ordinal numbers).

Cardinal numbers [números cardinales] are used to indicate the quantity of something.

Some cardinal numbers can have both genders [géneros] and agree in gender with the noun they accompany.

Form

Some cardinal numbers can have both genders and have the same gender as the noun that they attached.

These are uno (and the compounds and combinations ending with uno) and the hundreds from doscientos to novecientos (and the combinations ending with them):

21 – veintiuno:

  • isolated: without change ⇒ veintiuno;
  • before a masculine noun: deletes -o ⇒ veintiún*;
  • before a feminine noun: -o changes to -a ⇒ veintiuna.

31 – treinta y uno (+ 41, 51, 61, 71, 81, 91, 101, etc.):

  • isolated: without change ⇒ treinta y uno;
  • before a masculine noun: deletes -o ⇒ treinta y un;
  • before a feminine noun: -o changes to -a ⇒ treinta y una.

200 – doscientos (+ 300, 400, 500, …, 1.700, …, 2.345.600, etc.):

  • isolated: without change ⇒ doscientos;
  • before a masculine noun: without change ⇒ doscientos;
  • before a feminine noun: -os changes to -as ⇒ doscientas.

* In the case of veintiún, a graphic accent must be added.

Example

21:

  • isolated: la fila número veintiuno;
  • before a masculine noun: veintiún hombres;
  • before a femenine noun: veintiuna mujeres.

31 (+ 41, 51, 61, 71, 81, 91, 101, etc.):

  • isolated: la fila número treinta y uno;
  • before a masculine noun: treinta y un hombres;
  • before a femenine noun: treinta y una mujeres.

200 (+ 300, 400, 500, …, 1.700, …, 2.345.600, etc.):

  • isolated: la fila número doscientos;
  • before a masculine noun: doscientos hombres;
  • before a femenine noun: doscientas mujeres.

Cardinal numbers are used to indicate:

  • numbers of people, animals, or things;
  • measurements, weights, and distances;
  • age;
  • dates;
  • hours;
  • years.

Summary

Some cardinal numbers can have both genders in Spanish and agree in gender with the noun they accompany.

These are uno and the compounds that end with it, and the hundreds from doscientos to novecientos and the combined ones that end with them.

For example:

— «treinta y un niños. / treinta y una niñas.» = 31.

— «doscientos euros. / doscientas monedas.» = 200.
