21 22 23 In Spanish | Write And Say Them Right

Veintiuno, veintidós, and veintitrés are the correct Spanish forms for 21–23, with accent marks on 22 and 23.

If you only need a fast translation, here it is: 21 is veintiuno, 22 is veintidós, and 23 is veintitrés. Done.

Now, if you want to write these numbers cleanly in real sentences (dates, ages, prices, time, percentages), you’ll run into a few tricky spots: accent marks, gender, and a shortened form of 21 that shows up before masculine nouns. This article walks you through those spots without making you wade through fluff.

How 21, 22, And 23 Work In Real Spanish

Spanish writes 21–29 as one word, not two. So you don’t write “veinte y dos” for 22. You write veintidós.

These three have a simple pattern:

• 21:veintiuno
• 22:veintidós (accent on ó)
• 23:veintitrés (accent on é)

The accents are not decoration. They mark the stressed syllable and they must be written in standard Spanish spelling. That’s why veintidos and veintitres look off in edited text.

Quick pronunciation notes

You’ll usually hear these as one smooth chunk. The “vein-” part stays light, and the stress lands where the accent sits:

• veintiuno: stress lands on “u” (…ti-U-no)
• veintidós: stress lands on “dós”
• veintitrés: stress lands on “trés”

If you’re reading out loud and want to sound natural, don’t pause between “veinti” and the last part. Treat it as one word.

21 22 23 In Spanish rules for spelling and accents

Let’s clear the writing rules that cause most mistakes. Two things matter most: (1) when accents appear, and (2) what happens to uno inside 21.

Why 22 and 23 carry accent marks

Veintidós and veintitrés are stressed on the last syllable, and Spanish marks that stress with a written accent in these cases. If you write Spanish for school, work, captions, or anything public-facing, keep those accents in place.

If you’re typing on a phone, long-press the vowel to pick the accented version. On a computer, you can add them with keyboard shortcuts (more on that later), or just copy/paste “ó” and “é” when you need them.

21 changes shape before many masculine nouns

Veintiuno behaves like uno. In front of many masculine nouns, Spanish often shortens uno to un. With 21, that creates veintiún.

So you’ll see:

• Veintiún años (21 years)
• Veintiún libros (21 books)

Yet you’ll also see times when the full form stays, like when the number stands alone or answers a question:

• —¿Cuántos alumnos hay? —Veintiuno.

21 matches feminine nouns with “veintiuna”

In front of feminine nouns, Spanish uses veintiuna:

• Veintiuna personas (21 people)
• Veintiuna casas (21 houses)

This is one of those places where English habits can sneak in. If you keep saying “veintiuno personas,” many native speakers will notice.

For the formal rule set, the Real Academia Española lists these number forms and the gender variants in its guidance on cardinal numbers: RAE “cardinales” (cardinal numbers).

Percentages are a common trap

People often write “veintiún por ciento,” since it feels like a noun is coming next. In careful Spanish, you write veintiuno por ciento, since “por” is a preposition and the expression works as an adverbial phrase. The RAE and Fundéu both spell that out clearly in their notes on usage.

Here are the forms you want in edited text:

• veintiuno por ciento
• treinta y uno por ciento

You can check the RAE’s usage note here: RAE “veintiuna personas, veintiuno por ciento”.

And here is Fundéu’s recommendation, with the same point explained in plain language: Fundéu: “veintiuno por ciento, no ‘veintiún por ciento’”.

Where you’ll see 21–23 most often

Knowing the bare translations is nice, but the real win is using them smoothly in the places people actually write numbers.

Dates

Spanish often uses “el” before a date, and the day number can appear as a numeral or as a word. In words, you’ll see:

• El veintiuno de marzo
• El veintidós de mayo
• El veintitrés de junio

When the context is a schedule or a calendar, digits are also common: “el 22 de mayo.” Both styles exist.

Ages

Ages are where veintiún shows up a lot:

• Tengo veintiún años.
• Cumple veintidós años este mes.
• Va a cumplir veintitrés.

Notice the last sentence: when you don’t say “años,” the number stands alone, so veintitrés stays as-is.

Money

Prices can be written with digits, but the word forms pop up in contracts, invoices, and formal writing:

• Veintiún euros
• Veintidós dólares
• Veintitrés pesos

Currency words vary by region, but the number forms stay the same.

Time in 24-hour format

In many places, especially schedules and travel, 24-hour time is normal. Spanish can write 22:00 as “las veintidós.” You’ll even see phrases like:

• Son las veintidós treinta. (22:30)

If you want a dictionary entry that shows this time use, the RAE includes it in the definition of veintidós: RAE DLE entry for “veintidós”.

Common mistakes with 21, 22, And 23

These are the errors that pop up again and again in learner writing, captions, and even signage. Fixing them makes your Spanish look cleaner right away.

Leaving off the accent marks

“Veintidos” and “veintitres” show up a lot online. In edited Spanish, they should be veintidós and veintitrés. If you’re writing for school, clients, or anything public, add the accents.

Writing 22 or 23 as two words

You might see “veinte y dos” in very old texts or playful writing, but modern standard Spanish uses the one-word forms for 21–29. So stick with veintidós and veintitrés.

Using “veintiún” before “personas”

Since personas is feminine, it calls for veintiuna: “veintiuna personas.” That’s the form the RAE points to in its usage note.

Forgetting that “veintiuno” is right with percentages

Write veintiuno por ciento. Not veintiún por ciento. This one matters because it’s a frequent pattern in news, reports, and business writing, so readers spot the mistake fast.

How to type accents fast

If accents slow you down, you’ll skip them. So let’s make them easy.

On phones and tablets

Long-press the vowel and pick the accented version. You’ll need:

• ó for veintidós
• é for veintitrés

On Windows

Two practical options:

• Turn on the US-International keyboard layout, then type an apostrophe + vowel for many accents.
• Use Alt codes if you already know them, though that’s slower unless you do it daily.

On Mac

Hold the vowel key, then pick the accent from the pop-up. It’s quick and you don’t need to change keyboard layouts.

On Chromebook

Use the built-in accented character picker, or switch to a Spanish keyboard layout for longer writing sessions.

Table 2 (after ~60% of article)

Context	Best form	Sample line
Answering “How many?”	veintiuno	—¿Cuántos son? —Veintiuno.
Before a masculine noun	veintiún	Vive allí desde hace veintiún años.
Before a feminine noun	veintiuna	Asistieron veintiuna personas.
Percentages	veintiuno por ciento	Subió veintiuno por ciento en un mes.
Dates in words	el veintidós / el veintitrés	La cita es el veintidós de mayo.
24-hour time	las veintidós	Sale a las veintidós.
Age stated with “años”	veintiún	Tiene veintiún años.
Age stated alone	veintitrés	Va a cumplir veintitrés.

Practice that sticks without drilling forever

If you want these to feel automatic, you don’t need a long study session. You need a few reps in the exact contexts where mistakes happen.

Mini drill: swap the noun

Say each line out loud twice, then write it once:

• ____ años (use 21)
• ____ personas (use 21)
• ____ libros (use 21)
• ____ por ciento (use 21)

Answers, in order: veintiún, veintiuna, veintiún, veintiuno.

Mini drill: accents under speed

Type these three words five times, fast, without missing accents:

• veintiuno
• veintidós
• veintitrés

Then type one sentence that uses each of them. This forces your fingers to learn the accents, not just your eyes.

A clean checklist for writing 21–23 without second-guessing

If you want a simple mental check that works every time, run this quick list:

• If it’s 22 or 23, write the accent: veintidós, veintitrés.
• If 21 stands alone, write veintiuno.
• If 21 comes right before a masculine noun, write veintiún.
• If 21 comes right before a feminine noun, write veintiuna.
• If it’s a percentage, write veintiuno por ciento.

Once you’ve used these forms in a handful of messages, captions, or short paragraphs, they stop feeling like rules and start feeling like normal Spanish.
