Don't worry, we've all been there. Numbers are a fundamental part of any language, and Spanish is no exception. The good news? Once you spot the patterns, counting to 100 is a piece of cake—or as they say in Spanish, ¡es pan comido!

This guide will break down Spanish numbers 1-100 into simple, digestible chunks. Ready? ¡Uno, dos, tres, vamos!

The Foundations: Numbers 0-15

First things first, let's learn the essentials. The numbers from 0 to 15 in Spanish are unique, so you'll need to memorize them. Think of them as the key building blocks for everything that follows.

Uno vs. Un

You might have seen the number one written as both uno and un. What's the deal?

  • Use uno when you're just counting (uno, dos, tres...) or when it stands alone.
  • Use un right before a masculine noun. For example, un gatoa cat.
  • For feminine nouns, you use una! For example, una casaa house.

The First Pattern: Numbers 16-19

Great job! Now for our first pattern. The numbers from 16 to 19 are formed by smashing "diez y" (ten and) together with the single digits.

Notice how diez y seis becomes dieciséis.

  • 16 - dieciséissixteen (diez + y + seis)
  • 17 - diecisieteseventeen (diez + y + siete)
  • 18 - dieciochoeighteen (diez + y + ocho)
  • 19 - diecinuevenineteen (diez + y + nueve)

Watch for Accents!

Don't forget the accent on dieciséis! It's there to keep the stress on the correct syllable.

The Tens: 20, 30, 40...

Next, let's learn the tens. These are your new anchor points for building the rest of the numbers up to 100.

  • 20 - veintetwenty
  • 30 - treintathirty
  • 40 - cuarentaforty
  • 50 - cincuentafifty
  • 60 - sesentasixty
  • 70 - setentaseventy
  • 80 - ochentaeighty
  • 90 - noventaninety

Putting It All Together: 21-99

This is where the magic happens! There are two simple rules for combining the tens and the ones.

Rule 1: The Twenties (21-29)

Just like we saw with 16-19, the numbers from 21-29 are also squished into one single word. The veinte changes to veinti- and you just add the next number.

  • 21 - veintiunotwenty-one
  • 22 - veintidóstwenty-two
  • 23 - veintitréstwenty-three
  • 25 - veinticincotwenty-five
  • 29 - veintinuevetwenty-nine

Rule 2: From 31 Onwards

From 31 all the way to 99, the pattern gets even easier! You just use three separate words: the ten, the word y (and), and the one.

Formula: [The Ten] + y + [The One]

  • 31 - treinta y unothirty-one
  • 45 - cuarenta y cincoforty-five
  • 68 - sesenta y ochosixty-eight
  • 99 - noventa y nueveninety-nine

This is a key difference. The 20s are one word, but 31 and up are three words. See for yourself with this slider!

The Grand Finale: 100!

You made it! The number 100 is simple.

  • 100 - cienone hundred

A Peek Ahead: Cien vs. Ciento

When you're saying "100" exactly, you use cien. For example, "Tengo cien libros" (I have 100 books). When you start counting from 101 to 199, cien changes to ciento. For example, 101 is "ciento uno." A little tip for your future studies!

Frequently Asked Questions

How do you say 100 in Spanish?

For the number 100 exactly, you say 'cien'. If you are counting past 100 (e.g., 101), you use the form 'ciento'.

What's the difference between 'uno' and 'un' in Spanish?

You use 'uno' when counting ("uno, dos, tres...") or when the number stands alone. You use 'un' when it comes before a masculine noun, acting like 'a' or 'an' (e.g., 'un libro' - a book).

Is 'veintiuno' one word or three?

All the numbers from 21 to 29 are written as a single word in modern Spanish (e.g., 'veintiuno', 'veintidós'). The older form 'veinte y uno' is now considered incorrect.
