How many Spanish words you really need.
What the first 1,000, 3,000 and 8,000 words buy you, why one Spanish verb counts as dozens of words, and the level-by-level numbers nobody official gives.
October 25, 2026
The most common word in Spanish is de. In the 20-million-word corpus behind Mark Davies’s A Frequency Dictionary of Spanish (2006), the thousand most common words make up almost 80 percent of the words in its fiction. That sounds like most of the way to reading a novel until you do the arithmetic: at 80 percent, one word in five is a stranger. On a page with a hole where every fifth word should be, you spend your time decoding.
The share of a particular text you know is a more useful number than any count of the words it takes to be fluent. In Spanish, you also have to settle what a word is before any total means much.
The short answer
About 1,000 words to start reading Spanish written for learners, about 3,000 to know nearly nine words in ten of ordinary written Spanish, and, by the best-known estimate, 8,000 to 9,000 word families to read books for native speakers without help. That last figure is Paul Nation’s, from 2006, and he worked it out for English.
No official body sets a word count for A1, B1 or B2. The CEFR describes vocabulary by what you can do with it. A better target than “fluent” is the thing you want to read: when you know about 98 percent of its words, you can read it.

In English, talk has four forms, few enough to count on one hand: talk, talks, talked, talking. Its Spanish counterpart, hablar, has more than forty written forms before you attach a single pronoun: hablo, hablas, habló, hablaba, hablaré, hablaría, hable, hablara, hablando, and on through every person and tense.
Irregular verbs are worse, because their forms don’t look related. In our twenty-one free Spanish stories, ir turns up in thirteen different forms: voy, vas, va, vamos, van, iba, iban, iría, fue, fueron, fuiste, ido and ir itself. In the same stories, fue belongs to two verbs: it is the past of ir, “went”, in six of them, and the past of ser, “was”, in five.
Every vocabulary figure depends on its unit. Davies, and frequency dictionaries like his, count lemmas: one headword for all the forms of a verb, so hablo and hablaron are both hablar, while pintar, pintura and pintor are three separate entries. Paul Nation, the source of the figures you’ll see quoted most often, counts word families, and one family holds paint, painter and painting. A family is a bigger unit than a lemma, so the same vocabulary always sounds smaller in families.
If you’re learning Spanish, the lemma is the fairer count, with a catch: knowing ir doesn’t mean you’ll recognize fueron. You do much of your learning in Spanish inside the verb, and you won’t see any of it on a word list that prints only infinitives.
The first thousand words
Davies published his coverage figures in 2005, while he was building the dictionary. He split his corpus in roughly equal thirds between speech, fiction and non-fiction, with texts from Spain and Latin America, and tagged each of its 20 million words with its lemma. Each block of the most common Spanish lemmas covers this share of each kind of text:
| Most common lemmas | Speech | Fiction | Non-fiction |
|---|---|---|---|
| 1,000 | 87.8% | 79.6% | 76.0% |
| 2,000 | 92.7% | 86.1% | 84.0% |
| 3,000 | 94.0% | 89.6% | 88.2% |
Speech is more repetitive than writing: a thousand words cover almost nine in ten of the words people say, but only three in four of the words in non-fiction. That gap is one reason you can talk with a patient conversation partner before you can read the newspaper, and why “conversational” and “able to read” are different targets.
Read down any column and the gains shrink, a pattern Davies called a law of diminishing returns. The second thousand words add five to eight points of coverage, the third between one and four. Each thousand you learn is worth less than the one before, and you pay the most for the last few percent, the ones that make the difference between reading a page and decoding it.
The expensive last few percent
The usual bar is 98 percent, one unknown word in fifty, the share Marcella Hu and Paul Nation’s 2000 study suggested most readers need before a story makes sense on its own. We explain it in how to learn Spanish by reading. In 2006 Nation turned that share into a vocabulary size. Using fourteen lists of 1,000 word families built from the British National Corpus, he estimated that 98 percent of written English takes 8,000 to 9,000 word families, and 98 percent of spoken English 6,000 to 7,000.
Nation worked those numbers out for English and counted in families, so the Spanish figure in lemmas would be larger, by an amount we won’t guess at. Ninety-eight percent is also the optimum, and the minimum sits lower. In 2010 Batia Laufer and Geke Ravenhorst-Kalovski put a minimal threshold at 95 percent, about 4,000 to 5,000 word families in English, and found that readers’ comprehension kept improving with small gains in vocabulary, even when their coverage changed little.
Eight thousand word families is years of work, and you don’t have to wait for them, because coverage depends on the text as much as on you. If you know the thousand most common words and a story stays inside them, explaining a handful of new ones, you’re close to 98 percent today. That’s the logic of stories graded by level: the writer shrinks the book to fit your vocabulary, and you grow the vocabulary by reading.
A1, B1, B2: the unofficial numbers
Search for the vocabulary you need at each level and you’ll find confident figures, none of them from the people who wrote the levels. The CEFR, which the DELE exams follow, describes vocabulary range without numbers; its 2020 Companion Volume says that range “is generally acquired through reading widely”, and leaves it there. The Instituto Cervantes’ Plan curricular of 2006 lists the vocabulary for each level of Spanish by topic and gives no total.
Most of the research estimates are for English, and they don’t agree. Nation suggests a survival kit of about 120 words and phrases for A1, then the most frequent 1,000 word families for A2, 2,000 to 3,000 of the most frequent words for B1 and about 4,000 for B2. In 2009 James Milton reported how English learners scored on a test of the 5,000 most common words, and his figures come out higher than Nation’s at the bottom and lower at the top: 1,500 to 2,500 words at A2, 2,500 to 3,250 at B1, 3,250 to 3,750 at B2.
For a sense of the pace, look at Nausica Marcos Miguel and three colleagues, who followed students through three semesters of Spanish at a US university. In a 2023 paper they reported that by the end the learners recognized, on average, about 65 percent of the 3,000 most frequent Spanish words. That’s roughly 2,000 words after a year and a half of classes.
Put the studies side by side and you get working ranges, all of them estimates:
- A1: up to about 1,000 words, starting with that survival kit, used mostly in the present tense.
- A2: roughly 1,000 to 2,000 of the most common words.
- B1: roughly 2,000 to 3,000, and the past tenses that go with them.
- B2: 3,500 to 4,000 and up, the point where you can start on books for native speakers.
We match our stories to those bands. Beginner stories (A1–A2) stay inside about the 1,000 most common words, plus up to eight topic words listed with each story. Intermediate stories (B1), like the ones in our Spanish short stories for intermediate learners, stay inside about 2,500, plus up to twelve. Advanced stories (B2–C1) have no word limit.

Below is the opening of Un día en Madrid, one of our free intermediate stories, so you can see B1 on the page. A retired math teacher from Chile has a single day in the city and a perfect plan.
Ernesto tenía un solo día en Madrid y un plan perfecto, escrito con letra pequeña en una hoja de papel. A las nueve y diez de la mañana, ese plan ya no servía para nada.
Ernesto had only one day in Madrid and a perfect plan, written in small handwriting on a sheet of paper. By ten past nine in the morning, that plan was already useless.
Ernesto era un profesor de matemáticas jubilado de Valparaíso, en Chile. Tenía setenta años y era su primer viaje a Europa. Al día siguiente tomaba un tren a Granada, así que organizó con cuidado cada minuto de su día en Madrid. Primero iría al Palacio Real, después a la Plaza Mayor y luego al parque del Retiro. Al final del día, quería ver la puesta de sol desde el Templo de Debod.
Ernesto was a retired math teacher from Valparaíso, in Chile. He was seventy years old, and it was his first trip to Europe. The next day he was taking a train to Granada, so he had carefully planned every minute of his day in Madrid. First he would go to the Royal Palace, then to the Plaza Mayor and after that to Retiro Park. At the end of the day, he wanted to watch the sunset from the Temple of Debod.
Pero delante del Palacio Real había una cola enorme de turistas. Un guardia le explicó que la espera era de dos horas, como mínimo. Ernesto miró su hoja con tristeza y tachó la primera línea.
But in front of the Royal Palace there was an enormous line of tourists. A guard explained that the wait was two hours, at the very least. Ernesto looked sadly at his sheet of paper and crossed out the first line.
Count the verbs and you get sixteen, only one of which, ver, appears in the form a word list prints. The rest are tenía (twice), servía, era (three times), tomaba, quería, había, organizó, explicó, miró, tachó, the conditional iría and the participle escrito. Thirteen of the sixteen are in one of the two past tenses, the imperfect for background and the preterite for what happened, the contrast we designed our B1 stories to teach. Tomaba is the subtle one: an imperfect for a plan rather than a habit, where English would say “was taking”.
Then look at iría, “he would go”: the infinitive ir plus the conditional ending -ía, which you can guess once you know the pattern. The past forms fue and fueron, “went”, look nothing like ir, so if you learned ir from a list, you’ve met one of its forms.
Three words in these paragraphs are on the story’s list of key words: jubilado (retired), cola (a line of people) and tachar (to cross out). If those are the only words you don’t know, you’re reading at almost exactly 98 percent: three unknown in 142. In a story at your level you notice the new words because there are so few of them, and in Facing Pages you can tap any word for its meaning in that sentence, with its dictionary form, so tachó comes back as tachar.
Fluent is the wrong finish line
Native speakers know far more words than any learner target above. The most careful estimate is for English: in 2016 Marc Brysbaert and three colleagues, working from a large online vocabulary test, put the average 20-year-old American at about 42,000 lemmas, from 27,000 for the lowest five percent to 52,000 for the highest. The 2014 edition of the Real Academia Española’s dictionary has 93,111 entries.
You won’t get fluent by working toward either number, because fluency in reading is a relationship between a reader and a text. With 2,500 words you can be fluent in a B1 story and still need a dictionary at your elbow for a novel written for adult native speakers. Pick the text first. If you’d have to guess one word in fifty or fewer on a page, read it; if it’s more, find something easier and read a lot of it. With each story you finish at 98 percent, you pick up words you’ll need for the next one.
The figure worth tracking is how many words on the page in front of you are new, and you can check it before you commit to a chapter.
Questions
How many words do you need to know to be fluent in Spanish?
There’s no agreed number, because “fluent” isn’t a vocabulary size. The best-known estimate for reading books for native speakers without help is 8,000 to 9,000 word families (Paul Nation, 2006), but Nation worked it out for English. For everyday conversation you need far fewer: the 3,000 most common Spanish lemmas cover 94 percent of the words in spoken Spanish.
How many words do you need to be conversational in Spanish?
People repeat their basic words much more when they talk than when they write. In Mark Davies’s corpus, the 1,000 most common Spanish lemmas cover almost 88 percent of the words people say and the 3,000 most common cover 94 percent. Paul Nation’s estimate for 98 percent of spoken English is 6,000 to 7,000 word families, against 8,000 to 9,000 for written English.
How many words do you need to know for B1 Spanish?
No official body gives one. Research estimates, most of them for English, cluster around 2,000 to 3,000 of the most frequent words. Our intermediate (B1) stories stay inside about the 2,500 most common Spanish words, plus up to twelve topic words listed with each story.
How many words do you need for A1 and A2 Spanish?
A1 runs from a survival kit of about 120 words and phrases, Paul Nation’s suggestion, up to about 1,000 words. A2 is roughly 1,000 to 2,000 of the most common words. Both are estimates: the CEFR and the DELE exams describe what you can do at each level and give no word counts.
How many words do native Spanish speakers know?
There’s no widely cited count for Spanish. For English, Marc Brysbaert and colleagues estimated in 2016 that the average 20-year-old American knows about 42,000 lemmas, from 27,000 to 52,000 across the middle 90 percent of people. That figure doesn’t transfer to Spanish, and you don’t need anything like it to read well.
How many words do you need to know to understand Spanish?
Enough to know about 98 percent of the words in whatever you’re reading or hearing. For Spanish written for learners, that can mean as few as 1,000 words. For ordinary Spanish, the 3,000 most common lemmas cover nearly 90 percent of written text and 94 percent of speech; books for native speakers take far more, 8,000 to 9,000 word families by the best-known estimate, which Paul Nation made for English.
How many words are there in Spanish?
The 2014 edition of the Real Academia Española’s dictionary, the Diccionario de la lengua española, has 93,111 entries. Mark Davies’s frequency dictionary lists the 5,000 most common, and the 3,000 most common cover about 88 to 94 percent of the words in ordinary Spanish.
