Cardinal Numbers: Basics

This lesson covers the fundamental cardinal numbers in Spanish from 1 to 20. You will learn how to count using these basic numbers, which form the foundation for everyday conversations and practical use.

Numbers from 1 to 20

Here are the Spanish numbers one through twenty:

1: Uno11: Once
2: Dos12: Doce
3: Tres13: Trece
4: Cuatro14: Catorce

6: Seis16: Dieciséis
7: Siete17: Diecisiete
8: Ocho18: Dieciocho
9: Nueve19: Diecinueve

How these numbers are structured

The numbers from 0 to 9 are called "unidades" (units). From 0 to 15, each number is unique and has its own form without a repeating pattern.

Numbers 16 to 19 are formed by combining "dieci" with the unit numbers, for example, "Diecisiete" (17) blends "dieci" (ten) and "siete" (seven).

The number 0 is pronounced as "cero".

Common numeric expressions

  • Un par means 2. Example: "Un par de zapatos" (A pair of shoes).
  • Una docena means 12. Example: "Una docena de huevos" (A dozen eggs).

Comparison between English and Spanish numbers

Unlike English, Spanish uses unique words for numbers from 11 to 15, which do not follow a pattern like English's "eleven," "twelve," etc. Also, Spanish combines prefixes like "dieci" with unit numbers from 16 to 19, whereas English does not use this structure.

Useful Spanish phrases include simple number-related verbs such as "contar" (to count), "sumar" (to add), "restar" (to subtract), and "multiplicar" (to multiply), important for mathematical contexts.
