You’ll say uno to cien smoothly by learning the 1–15 core words, the 16–29 pattern, and the accent marks on 22, 23, 26.
Numbers sit inside daily Spanish. Prices, times, dates, addresses, scores, ages. If your brain freezes after “veinte,” you’re not alone. The fix isn’t memorizing 100 separate items. It’s learning a few building blocks, then spotting the repeats.
This page gives you the full set from 1 to 100 written out, then shows how the pieces snap together. You’ll get pronunciation cues, spelling rules that trip people up, and a few fast drills you can do in two minutes.
Why Spanish numbers feel tricky at first
English builds early numbers with a tidy pattern. Spanish does too, but it hides the pattern behind spelling changes, accent marks, and a couple of gender swaps. Once you know where those switches happen, the rest starts to feel predictable.
Three spots cause most slips:
- 16–29 compress into one word in common writing: dieciséis, veintidós, veintisiete.
- 21, 31, 41, 51, 61, 71, 81, 91 can change with gender before nouns: veintiún libros, veintiuna casas.
- Accent marks appear on a few forms, even when you might not expect them: dieciséis, veintidós, veintitrés, veintiséis.
1 to 100 in Spanish in Words with pronunciation tips
Read the list once, then read it again out loud. Keep your pace steady. Spanish rhythm likes clean syllables, so don’t rush the middle of longer words.
Numbers 1 to 15
These are the core words you’ll reuse all the time:
- 1 uno (OO-noh)
- 2 dos (dohs)
- 3 tres (trehs)
- 4 cuatro (KWAH-troh)
- 5 cinco (SEEN-koh)
- 6 seis (SAYS)
- 7 siete (SYEH-teh)
- 8 ocho (OH-choh)
- 9 nueve (NWEH-beh)
- 10 diez (DYEHS)
- 11 once (OHN-seh)
- 12 doce (DOH-seh)
- 13 trece (TREH-seh)
- 14 catorce (kah-TOR-seh)
- 15 quince (KEEN-seh)
Numbers 16 to 19
These attach diez to the unit. Pay attention to accents.
- 16 dieciséis (DYEH-see-SEHYS)
- 17 diecisiete (DYEH-see-SYEH-teh)
- 18 dieciocho (DYEH-see-OH-choh)
- 19 diecinueve (DYEH-see-NWEH-beh)
Numbers 20 to 29
Twenty stands alone as veinte. From 21 to 29, Spanish usually fuses the words into one: veinti + unit. Three forms carry an accent mark.
- 20 veinte
- 21 veintiuno
- 22 veintidós
- 23 veintitrés
- 24 veinticuatro
- 25 veinticinco
- 26 veintiséis
- 27 veintisiete
- 28 veintiocho
- 29 veintinueve
Tens 30 to 90
These are the “anchor” words for the rest of the chart:
- 30 treinta
- 40 cuarenta
- 50 cincuenta
- 60 sesenta
- 70 setenta
- 80 ochenta
- 90 noventa
Numbers 31 to 99
From 31 onward, you build “tens + y + unit.” Keep y as a quick “ee” sound. The tens word stays the same. The unit word stays the same.
Here are full sets by tens:
- 31 treinta y uno, 32 treinta y dos, 33 treinta y tres, 34 treinta y cuatro, 35 treinta y cinco, 36 treinta y seis, 37 treinta y siete, 38 treinta y ocho, 39 treinta y nueve
- 41 cuarenta y uno … 49 cuarenta y nueve
- 51 cincuenta y uno … 59 cincuenta y nueve
- 61 sesenta y uno … 69 sesenta y nueve
- 71 setenta y uno … 79 setenta y nueve
- 81 ochenta y uno … 89 ochenta y nueve
- 91 noventa y uno … 99 noventa y nueve
If you want each number spelled out in one sweep, keep reading. The table below gives the entire 1–100 list in a compact form, plus the rule that builds each chunk.
Patterns that make spelling stick
Memorize the anchors: 1–15, 20, then the tens (30, 40, 50, 60, 70, 80, 90). Once those sit in your head, you can form the rest on demand.
Writing rules in Spanish treat many numerals as single words, and some as multiple words. The Real Academia Española lays out when numerals fuse and when they stay separate. You can check the official notes in RAE guidance on numerals.
Text type can change whether you pick digits or words. If you’re writing prose, many style guides prefer words for smaller numbers, then digits as numbers grow. Fundéu summarizes that choice and points back to the academic ortography in Fundéu guidance on writing numbers.
When you’re studying, stick with words first. You’re training your mouth and your ear, not your spreadsheet.
| Range | How It’s Written | Fast Notes |
|---|---|---|
| 1–15 | Single words | Core set to memorize. |
| 16–19 | dieci + unit (one word) | Accent on dieciséis. |
| 20 | veinte | Standalone anchor. |
| 21–29 | veinti + unit (one word) | Accents: veintidós, veintitrés, veintiséis. |
| 30, 40, 50, 60, 70, 80, 90 | Single words | Learn these as anchors for 31–99. |
| 31–99 | Tens + y + unit (three words) | y only appears between tens and units in this range. |
| 100 | cien (or ciento + …) | cien is 100 exact; ciento starts 101+. |
| Gender forms | uno → un/una before nouns | 21, 31, 41… follow the same shift when used as adjectives. |

Pronunciation and spelling traps that slow you down
If you can say the list but your writing still looks off, you’re likely hitting one of these traps. Fix each one once, then you won’t keep relearning it.
Accent marks on 16, 22, 23, 26
Spanish accents mark stress. In these fused forms, the written accent keeps the stress where speakers place it: dieciséis, veintidós, veintitrés, veintiséis. If you leave the accent out in casual notes, people still get you. In formal writing, include it.
One word versus three words
It’s tempting to write veinte y dos. Standard spelling uses veintidós. After 30, switch to three words: treinta y dos. The academic ortography on numeric expressions spells out these patterns in RAE chapter on numeric expressions.
Uno changing before nouns
When a number works like an adjective, uno changes: un libro, una casa. The same thing happens with 21 and with “tens + y uno” when they sit before a noun: treinta y un días, treinta y una horas. Say the base form when you’re counting in a list. Swap it when it points at a noun.
If you’re learning Spanish through structured lessons, the Centro Virtual Cervantes has an A1 activity built around the 1–100 set. It’s handy for practice prompts and classroom-style tasks: Los números del 1 al 100.
| What You Want To Say | Correct Form | Why It Changes |
|---|---|---|
| 21 books | veintiún libros | uno drops to un before a masculine noun. |
| 21 houses | veintiuna casas | Feminine noun triggers una. |
| 31 minutes | treinta y un minutos | Same shift with “tens + y uno.” |
| 31 hours | treinta y una horas | Feminine noun triggers una. |
| I counted: 1, 2, 3… | uno, dos, tres… | Pure counting keeps uno. |
| Page 21 | página veintiuno / página 21 | In labels, both forms appear by style. |
| Room 41 | habitación cuarenta y uno | Labels tend to keep the base numeral form. |
