Portuguese vs Spanish: How Different Are They?
The honest comparison: what the two languages share, the false friends that will embarrass you, and the one fact almost every guide gets wrong about who understands whom.
How similar are Portuguese and Spanish?
Portuguese vs Spanish is about as close as two separate languages get. They score 89% lexical similarity on Ethnologue's standard wordlist and share almost the same grammar skeleton. On paper, a reader of one follows much of the other. Out loud the gap opens fast, and it opens unevenly in one direction.
Portuguese vs Spanish: how similar are they really?
Very, and the number backs it up. Both descend from Latin, both sit in the West Iberian branch of Romance, and they grew up next door on the same peninsula. Ethnologue scores their lexical similarity at 0.89: 89 of every 100 words on a standard comparison wordlist look and mean roughly the same in both.
One honest footnote on that number. Lexical similarity counts matching words on a list. It says nothing about whether you can follow a conversation, because speech also runs on sound and rhythm.
Same proverb, cousin words:
| Language | Sentence |
|---|---|
| Spanish | Al buen entendedor pocas palabras bastan. |
| Portuguese | Ao bom entendedor poucas palavras bastam. |
| English | A word to the wise is enough. |
Four of those six words are near-identical on the page. Read them aloud in Madrid and Lisbon and they sound like two unrelated things.
So, are Portuguese and Spanish similar? Similar enough to read, different enough that you still have to learn one. Speak either and you'll pick up newspaper headlines in the other on day one. You will not follow a phone call. They're separate languages, not dialects of each other.
Can Portuguese speakers understand Spanish?
Usually, yes. And here's the fact most comparisons skip: intelligibility between these two languages is not mutual. It runs downhill, in one direction.
John Jensen tested it properly. His 1989 study in the journal Hispania measured college students listening both ways and found the languages intelligible at roughly a 50 to 60 percent level, with Portuguese speakers understanding Spanish better than Spanish speakers understood Portuguese. Brazilian listeners scored near the top of that range; Spanish listeners near the bottom. Ask a Brazilian and a Colombian and you'll hear the same thing without the study.
Why the traffic runs one way
The cause is sound, not vocabulary. Both directions share the same word list. Only one direction meets a sound system it has no slots for.
| Spanish | Portuguese | |
|---|---|---|
| Vowel phonemes | 5 (a, e, i, o, u) | 8 oral plus 5 nasal in Brazilian Portuguese; European Portuguese adds another |
| Nasal vowels | none | yes, and they change meaning |
| Unstressed vowels | keep their full quality | reduce, and in Portugal nearly vanish |
A Portuguese speaker listening to Spanish hears a smaller, tidier version of sounds they already own. Every Spanish vowel has a home in a Portuguese ear. A Spanish speaker listening to Portuguese meets nasal vowels their language lacks and swallowed syllables it never swallows, and there's nowhere to file them.
Written beats spoken, in both directions
State this one plainly, because it explains most of the confusion: written intelligibility is far higher than spoken intelligibility, both ways. Wikipedia's comparison of the two languages notes that mutual intelligibility is greater when written rather than spoken. Take sound out and they snap back together: someone who can't follow a Brazilian podcast can still read a Brazilian news site and get the gist.
One more wrinkle. Brazilian Portuguese is easier on Spanish ears than European Portuguese, because Brazilian vowels stay open while Portugal reduces them hard. If you've "tried Portuguese and failed," try Brazilian audio first. Our guide to the language of Brazil covers how the two standards drifted apart.
Portuguese and Spanish false friends
This is the section to bookmark. The two languages share so much vocabulary that the words which don't match become the dangerous ones: you read them, recognise them, and get them confidently wrong. Every pair below was checked in both directions.
| Word | In Spanish | In Portuguese | The trap |
|---|---|---|---|
| embarazada / embaraçada | pregnant | embarrassed, tangled up | Say estou embaraçada in Brazil and you're flustered, not expecting. Portuguese for pregnant is grávida. |
| exquisito / esquisito | exquisite, delicious | strange, weird | The nastiest pair on this list. Call a Brazilian's cooking esquisita and you've called it odd. |
| borracha | a drunk woman (feminine of borracho) | rubber, an eraser | Ask a Spanish speaker for una borracha and you have not asked for stationery. Spanish for eraser is goma. |
| polvo / pulpo | polvo = dust, powder | polvo = octopus | Polvo on a Lisbon menu is octopus. Spanish octopus is pulpo; Portuguese dust is pó. |
| oficina | office | workshop, car repair garage | A Portuguese oficina fixes your car. Portuguese for office is escritório; Spanish for workshop is taller. |
| rato | a while, a short time | rat, mouse | Espera un rato is Spanish for "wait a moment." Um rato in Portuguese is a rodent. Spanish for mouse is ratón. |
| niño / ninho | niño = child, boy | ninho = nest | Spelled differently, pronounced almost identically, because Portuguese nh and Spanish ñ are the same sound. Portuguese for boy is menino; Spanish for nest is nido. |
| salsa | sauce | parsley | Order salsa in Brazil and you get the herb. Portuguese for sauce is molho; Spanish for parsley is perejil. |
| pegar | to hit, to stick, to glue | to grab, to catch, to take | Vou pegar o ônibus is Portuguese for "I'll take the bus." To a Spanish ear it reads closer to hitting one. |
| largo | long | wide, broad | Um rio largo is a wide river in Portuguese and a long one in Spanish. Portuguese for long is comprido or longo; Spanish for wide is ancho. |
The three that derail whole sentences
Some false friends aren't nouns at all, but the tiny words holding a sentence together. Portuguese fuses prepositions with articles, and three results collide head-on with ordinary Spanish words:
| Portuguese | Means | But in Spanish it means |
|---|---|---|
| no (em + o) | in the | no, not |
| dos (de + os) | of the | two |
| pelo (por + o) | for the, by the | hair |
So no carro is Portuguese for "in the car," and a Spanish reader parses it as "no car." One word, opposite meaning, and the sentence quietly stops making sense.
Portuguese vs Spanish pronunciation: the real divider
Keep one thing from this page: the grammar is close, the vocabulary is close, and pronunciation is where the two part company.
Spanish is famously regular out loud. Five vowels, each pronounced one way, stressed or not, so you can read any Spanish word correctly on sight. Portuguese asks for more.
Nasal vowels
Portuguese makes some vowels partly through the nose, and they change meaning. Spanish has none. Three endings do most of the work:
| Spelling | Sounds roughly like | Example | Meaning |
|---|---|---|---|
| ão | "ow" pushed through the nose | não | no |
| ãe | "eye" through the nose | mãe | mother |
| õe | "oy" through the nose | põe | he/she puts |
Try não: start saying "now" and let the sound escape through your nose halfway. It feels wrong the first twenty times, and Spanish speakers hear it as static until they train it.
Brazilian D and T go soft
In most of Brazil, d and t before an "ee" sound turn into "j" and "ch." So dia (day) is "JEE-ah," tia (aunt) is "CHEE-ah," noite (night) ends "NOY-chee." Spanish keeps its d and t crisp everywhere, which is why spoken Brazilian Portuguese sounds nothing like its spelling to a Spanish reader.
The sh sound
In Portugal, Rio de Janeiro and northeastern Brazil, an s at the end of a syllable becomes "sh." Os pastéis comes out "oosh pash-TAYSH." Spanish has no "sh" at all, which is much of why Portuguese strikes Spanish speakers as oddly Slavic.
Portuguese gives ch that same value (chuva, rain, is "SHOO-vah") where Spanish keeps a hard "ch," and Portuguese j is the soft sound in "measure" (jogar) where Spanish j is a throaty h (jugar).
European Portuguese eats its vowels
In Portugal, unstressed vowels shrink to almost nothing: telefone lands close to "tlfon." Brazilians keep them open and audible, which is why beginners, and Spanish speakers, find Brazilian Portuguese easier to follow.
Two sets of sound rules for letters that look identical. Our Portuguese alphabet guide and Spanish alphabet guide walk through each letter with its real sound.
Grammar differences between Portuguese and Spanish
Both conjugate verbs for six persons, place adjectives after nouns, run two genders and drop subject pronouns freely. Know one system and you know the shape of the other. Five differences are worth naming.
1. Portuguese has a personal infinitive. Spanish does not.
Portuguese can conjugate an infinitive for person, something no other major Romance language does.
| Portuguese | Spanish | English |
|---|---|---|
| A recepcionista pediu para esperarmos. | La recepcionista nos pidió que esperáramos. | The receptionist asked for us to wait. |
Where Spanish reaches for the subjunctive, Portuguese just adds an ending to the infinitive. Unsettling for a week, useful forever.
2. Ter does the work of both haber and tener
Spanish splits the job in two. Tener means to have something; haber builds the perfect tenses (he comido) and gives you hay, "there is." Portuguese hands nearly all of it to ter: tenho um carro (I have a car), tinha comido (I had eaten). Haver survives mostly as há, and Brazilians usually say tem even for that.
A trap hides in there. Portuguese tenho falado is not Spanish he hablado. The Portuguese present perfect describes something repeated up to now, closer to "I have been speaking."
3. Portuguese contracts almost everything
Spanish contracts two things: a + el = al, and de + el = del. That's the whole list. Portuguese merges four prepositions with every article, both genders, both numbers:
| Preposition | + o | + a | + os | + as |
|---|---|---|---|---|
| de (of, from) | do | da | dos | das |
| em (in, on) | no | na | nos | nas |
| a (to) | ao | à | aos | às |
| por (by, for) | pelo | pela | pelos | pelas |
These are obligatory. Vou ao mercado, sou do Brasil, estou na praia. Spanish speakers under-contract for months, and it marks them instantly.
4. Object pronouns sit in different places
Spanish puts clitic pronouns in front of the conjugated verb: ella le dio un libro. European Portuguese hooks them onto the end with a hyphen: ela deu-lhe um livro. Brazilian Portuguese swings them back to the front: ela lhe deu um livro. One sentence, three positions.
5. Both have ser and estar, and use them differently
Both carry two verbs for "to be," and the underlying rule is mostly shared. Mostly.
| English | Spanish | Portuguese |
|---|---|---|
| Smoking is forbidden | Está prohibido fumar (estar) | É proibido fumar (ser) |
| The chair is made of wood | La silla está hecha de madera (estar) | A cadeira é feita de madeira (ser) |
| Only one is correct | Sólo uno es correcto (ser) | Só um está correto (estar) |
Portuguese also leans on a third verb, ficar, where Spanish reaches for estar or quedar: onde fica o aeroporto? If the two-verb split is new to you, our ser vs estar guide teaches the rule that survives the exceptions, and it transfers to Portuguese with small adjustments.
Portuguese vs Spanish: which should you learn first?
Honest recommendation: learn Spanish first, unless you have a specific reason to pick Portuguese. Then come back for the other, which will cost you a fraction of the first.
The numbers say Spanish. Ethnologue's 2026 figures put it at roughly 487 million native speakers and 561 million total, fourth in the world, while Portuguese sits near 252 million native and 269 million total, tenth. Spanish is official in 20 countries, Portuguese in nine, though one of those nine is Brazil.
Resources say Spanish even louder. More apps, textbooks, podcasts, teachers, free material, and more people near you to practise with. Portuguese learners hit that wall much sooner, and the gap bites harder day to day than the speaker gap does.
Difficulty barely separates them. Both sit in the friendliest group of languages for English speakers, close enough that difficulty shouldn't cast the deciding vote. Our guide to the easiest languages to learn has the ranking and the study hours.
Where you're going beats all of it. Moving to Lisbon, joining a São Paulo team, or in love with a Brazilian? Learn Portuguese and ignore the numbers. Planning "somewhere in Latin America" or chasing job options? Learn Spanish.
One tiebreaker sits on Portuguese's side: hard sounds are easier to learn first than to bolt on later. Spanish speakers struggle for years to add nasal vowels; Portuguese speakers walk into Spanish on day one.
Made your pick? Our step-by-step plan for learning Portuguese and the matching plan for learning Spanish both start from zero.
What is portunhol?
Portunhol (portuñol in Spanish) is what comes out when speakers of the two languages meet in the middle and go for it. You speak your own language, borrow from the other, bend the endings until they fit, and communication happens anyway.
It isn't one thing. The term covers everything from two strangers code-switching at a bus station to genuine contact varieties with their own speakers. The most established forms live along Brazil's southern borders with Uruguay, Paraguay and Argentina, where families have mixed the two for generations, and along the Portugal-Spain border. In northern Uruguay it's a real local variety, not an improvisation.
Should you use it? For booking a hotel room, absolutely, and both sides will meet you halfway. As a learning strategy it carries a cost: portunhol works well enough that it removes the pressure to actually learn the second language, and plenty of learners plateau there for years.
The fix is boring and it works. Pick one language, learn its sound system properly, and let the shared vocabulary be a bonus instead of a crutch.
If you already speak Spanish (or Portuguese)
The head start is real and it is large. Hold one language already and you reach conversational level in the other far faster, because the grammar architecture, the tense system, the gendered nouns and most of the vocabulary carry straight across.
Reading transfers on day one. Listening takes months. Speaking is where the traps live.
The free vocabulary conversions
Word endings correspond so regularly you can convert thousands of words in your head:
| Spanish | Portuguese | Example |
|---|---|---|
| -ción | -ção | nación to nação (nation) |
| -sión | -são | pensión to pensão (pension) |
| final -n | final -m | jardín to jardim (garden) |
| -ano, -án, -ón | -ão | hermano to irmão (brother), melón to melão (melon) |
| ll | lh | maravilla to maravilha (marvel) |
| ñ | nh | España to Espanha (Spain) |
Learn those six lines and your passive vocabulary in the other language jumps overnight.
Five traps that catch transferring learners
- You'll read instead of listen. Reading feels easy, so transferring learners skip audio and then can't follow a real conversation. Front-load listening from week one.
- False friends get zero suspicion. A word you recognise never triggers a second look, which is what makes the table above worth memorising rather than skimming.
- Spanish speakers under-nasalise. Não said with a clean Spanish vowel isn't não, and it's the first thing that marks a Spanish accent in Portuguese. In the other direction, swallowing unstressed vowels is the giveaway: Spanish wants every vowel full and equal.
- The present perfect flips. Tenho falado and he hablado look like twins and say different things.
- Muito covers two Spanish words. Spanish splits muy (very) from mucho (much, many); Portuguese uses muito for both.
Start with the sound system, not the word lists. You already have the words. What you don't have yet is the ear.

Portuguese vs Spanish: the quick recap
How similar are they?
Ethnologue scores 89% lexical similarity. Similar enough to read across, different enough that you still have to learn one properly. They are separate languages, not dialects.
The asymmetry is the key fact
Portuguese speakers understand spoken Spanish better than Spanish speakers understand spoken Portuguese, per Jensen's 1989 study. Portuguese phonology is the bigger system, so every Spanish sound fits a Portuguese ear. The reverse is not true.
Written beats spoken, both ways
Take sound out of the equation and the two languages snap together. Someone who cannot follow the podcast can still read the news site.
The false friends to memorise
esquisito (weird, not exquisite), embaraçada (embarrassed, not pregnant), oficina (garage, not office), salsa (parsley, not sauce), largo (wide, not long), polvo (octopus, not dust).
Which to learn first
Spanish, for speakers and resources, unless your destination or your people say Portuguese. Learning either makes the other much cheaper.
