Learning Basic Numbers in Spanish: From 11 to 20


You need to learn basic Spanish numbers to have conversations

The truth is that you will find it extremely hard to completely avoid numbers in your Spanish conversations. You will use Spanish numbers in shops or restaurants, when asking for directions and addresses, or when talking about date and time. Therefore it is clear that learning the basic Spanish numbers should be one of the priorities when you start learning the Spanish language.

The logic behind Spanish numbers from 11 to 20

If you already know the very basic numbers in Spanish (from 1 to 10) it will not be very difficult for you to learn the following Spanish numbers. Knowing Italian or French language will also help, as Spanish numbers from 11 to 20 are actually very similar to Italian or French numbers.

Spanish cardinal numbers from 11 to 15

You will need to memorize Spanish numbers from 11 to 15 like you had to memorize the Spanish numbers from 1 to 10. However, there is a small hint: from 11 to 15 all Spanish numbers end with -ce (something like -teen in English, also for 11 and 12). The first part of the number is always somehow related to the respective 1-10 number (for example, 3 is tres and 13 is trece). All Spanish numbers from 11 to 15 follow:

  • once = 11(eleven)
  • doce = 12 (twelve)
  • trece = 13 (thirteen)
  • catorce = 14 (fourteen)
  • quince = 15 (fifteen)

Spanish cardinal numbers from 16 to 20

Spanish numbers from 16 to 19 don’t follow the English -teen logic, but they are constructed in the same way as numbers 17 to 19 in French or Italian. All Spanish numbers from 16 to 19 start with dieci- and then you simply add the respective 1-10 Spanish number (for example, 8 is ocho and 18 is dieciocho). All Spanish numbers from 16 to 19 follow: 

  • dieciséis = 16 (sixteen)
  • diecisiete = 17 (seventeen)
  • dieciocho = 18 (eighteen)
  • diecinueve = 19 (nineteen)

Just for a sense of completeness, number 20 in Spanish is veinte.
