Spanish 11–20 mix a few stand-alone words with a simple “dieci-” pattern, so you can learn the whole set in one sitting.
Get 11–20 under your belt and a lot of Spanish feels lighter. Ages, dates, page numbers, prices, and quick counts stop being a speed bump.
This lesson gives you the words, the spelling details, and a short drill you can repeat until the set comes out smoothly.
What these numbers do in real Spanish
Numbers pop up all day. A teacher calls a page. A friend mentions the 16th. A cashier says a total. When 11–20 are automatic, you can stay with the message instead of doing math in your head.
These numbers also train two habits: memorizing a few special forms, then spotting patterns. You’ll use both habits across Spanish.
How the 11–20 range is built
Spanish treats 11–15 as vocabulary, then fuses pieces for 16–19, and finishes with a standalone 20.
Numbers 11–15 are memorized
English has “eleven” and “twelve.” Spanish has its own set early in the teens. Learn them as complete words and practice them aloud.
- 11 is once
- 12 is doce
- 13 is trece
- 14 is catorce
- 15 is quince
Don’t hunt for logic here. Say them, spell them, and treat them like any other vocabulary list.
Numbers 16–19 follow the “dieci-” pattern
From 16 onward, Spanish combines “ten” with the unit number. Modern spelling fuses it into one word:
- 16dieciséis (dieci + seis)
- 17diecisiete (dieci + siete)
- 18dieciocho (dieci + ocho)
- 19diecinueve (dieci + nueve)
Keep the base dieci-, then attach the unit. No spaces, and no y in these fused forms.
20 is its own word
20 is veinte. It doesn’t use the dieci- pattern. Later you’ll meet veinti- in 21–29, so veinte is the anchor word to learn now.
How To Say 11-20 In Spanish with clean pronunciation
Clear pronunciation keeps numbers from sounding like other words. Aim for steady rhythm and clean vowels, even when you speak at speed.
Stress and the one accent you must learn
When a written accent mark appears, it points to the stressed syllable. In 11–20, the accent shows up in dieciséis. Stress the last syllable: die-ci-SÉIS.
For the rest, keep an even beat. Don’t break a number into separate chunks while speaking.
Sound notes that cut down mix-ups
- c in doce sounds like “s” in much of Latin America, and closer to “th” in parts of Spain. Both are normal.
- cho in dieciocho ends with a clear “ch” like “chess.”
- nue in diecinueve starts as one glide, not two separate vowels.
Quick mouth drill for cleaner numbers
Do this once before you practice the full list. Say seis three times, then attach it to dieci-: die-ci-séis. Next, say siete three times, then die-ci-sie-te. For dieciocho, hold the “oh” a touch so the word doesn’t rush: die-ci-o-cho. For veinte, keep the first syllable short and crisp: vein-te. This drill trains your tongue to stay relaxed, which helps your timing when you say numbers inside longer sentences.
Use the chart below as your main reference. Read it forward, then backward, then pick random entries.
| Number | Spanish | Pronunciation cue |
|---|---|---|
| 11 | once | ON-seh |
| 12 | doce | DO-seh |
| 13 | trece | TREH-seh |
| 14 | catorce | kah-TOR-seh |
| 15 | quince | KEEN-seh |
| 16 | dieciséis | dyeh-see-SAYS |
| 17 | diecisiete | dyeh-see-SYEH-teh |
| 18 | dieciocho | dyeh-see-OH-choh |
| 19 | diecinueve | dyeh-see-NWEH-beh |
| 20 | veinte | BAYN-teh |
Ways to use 11–20 in sentences
Numbers settle in when you use them inside short phrases. Say the full line out loud, then swap the number.
Age and birthdays
- Tengo quince años. (I’m fifteen.)
- Cumplo dieciséis mañana. (I turn sixteen tomorrow.)
- Mi cumpleaños es el trece de mayo. (My birthday is May 13.)
Dates, pages, and classroom Spanish
- Estamos en el diecinueve. (It’s the 19th.)
- Abre el libro en la página doce. (Open the book to page 12.)
- Cuenta del once al veinte. (Count from 11 to 20.)
Shopping and daily counts
- Son veinte dólares. (It’s twenty dollars.)
- Hay catorce manzanas. (There are fourteen apples.)
- Necesito dieciocho minutos. (I need eighteen minutes.)
Spelling rules that trip up learners
Most writing errors come from spacing and accents. Fix those and your numbers look natural.
Don’t split the fused forms
Diecisiete is one word. Same with dieciocho and diecinueve. Writing “diez y siete” reads like a classroom exercise, not daily Spanish.
Respect the accent in dieciséis
The accent in dieciséis changes the stress pattern and signals correct spelling. Add it even when you type in all lowercase.
Know the “c” and “qu” spellings
Quince uses qu before i to keep a hard “k” sound. Catorce keeps plain c before a. These patterns show up in many Spanish words.
Common situations and ready-made phrases
Use these as plug-and-play lines. Keep the sentence, swap the number, and you’ll get speaking reps in minutes.
| Situation | Spanish phrase | English meaning |
|---|---|---|
| Counting items | Hay once. | There are eleven. |
| Giving your age | Tengo trece años. | I’m thirteen. |
| Asking a price | ¿Cuánto cuesta? | How much does it cost? |
| Answering a price | Cuesta veinte. | It costs twenty. |
| Time needed | En quince minutos. | In fifteen minutes. |
| Page number | Página dieciocho. | Page eighteen. |
| Date | El catorce de abril. | April 14. |
| Class instruction | Del doce al dieciséis. | From twelve to sixteen. |
Practice method that makes the numbers stick
You don’t need a long study block. You need recall plus speaking, then a quick spelling check. This routine fits into ten minutes.
Minute 1: Count with a beat
Tap your finger and say 11 through 20 once. Keep a steady beat. If you stumble, restart at 11.
Minutes 2–4: Random recall cards
Write 11–20 on small slips of paper. Shuffle. Flip one, say the Spanish word, then spell it out loud. Keep a “correct” pile and a “redo” pile.
Minutes 5–7: Sentence swaps
Pick one frame, like Tengo ___ años. Run through the set twice. Then switch to a date frame, like El ___ de mayo.
Minutes 8–10: Write from memory
Write the full list once without looking. Check it against the chart. Fix the errors, then rewrite only the missed words.
Mini check: can you answer these without pausing?
Say each prompt out loud. If one feels slow, repeat that number inside a sentence five times.
- Say 14, then 18.
- Say 11, 12, 13 in one smooth row.
- Say “I’m 17” in Spanish.
- Say “Page 20” in Spanish.
- Spell dieciséis out loud.
One-page cheat sheet you can copy into notes
Keep this compact list in your notebook. Copy it by hand once, then hide it and recite it.
- 11–15: once, doce, trece, catorce, quince.
- 16–19: dieci- + unit, fused: dieciséis, diecisiete, dieciocho, diecinueve.
- 20: veinte.
- Accent: only dieciséis in this range.
- Drill: count up, count down, then random cards.
How To Say 11-20 In Spanish
Start by speaking the set in order until it flows. Then switch to random recall. Finish by writing the words from memory. Do that for three days and the numbers will feel natural in daily speech.
