Most English speakers assume that a Portuguese word spelled almost identically to an English one probably means the same thing. Most of the time that assumption is fine. Portuguese and English share plenty of vocabulary through Latin, and words like "hospital," "família," or "informação" mean exactly what they look like. The trouble is the assumption doesn't fail loudly. When it's wrong, it produces a fluent, confident, wrong reading, not a stumble, and one specific word on this list has embarrassed more English speakers in a Portuguese doctor's office than any other.

The word that gets almost everyone: constipado

If you tell a Portuguese doctor "estou constipado," you are not making an unusual medical confession. You're saying you have a cold, stuffy nose and all. Constipado means congested, as in a head cold, not constipated in the digestive sense. The word English speakers actually want for that is obstipado, a completely different term. This single false friend is common enough, and awkward enough when it goes wrong, that it's worth learning before any other word on this list.

The rest of the list you'll actually run into reading

Pretender means to intend or to plan to do something, not to pretend. "Pretendo visitar Lisboa" means "I intend to visit Lisbon," not "I'm pretending to visit Lisbon." To pretend, in the English sense of faking something, is fingir.

Puxar means to pull, not to push. This one shows up on actual doors: a sign reading "Puxe" is telling you to pull, and an English speaker who reads it as "push" walks straight into the door. Push is empurrar.

Esquisito means weird or strange, not exquisite. A restaurant review calling a dish esquisito is not a compliment. Exquisite, in the sense of refined or elegant, is requintado.

Novela means a soap opera, the long-running television kind Portugal and Brazil both produce constantly, not a novel. A novel, the book, is romance.

Livraria means bookstore, not library. A library, the place you borrow books rather than buy them, is biblioteca.

Parentes means relatives generally, not specifically parents. Your actual parents are your pais. If a news article mentions someone's parentes, it could be talking about cousins, aunts, or grandparents, not just mother and father.

Atualmente means currently or nowadays, not actually. "Atualmente, o preço subiu" means "Currently, the price has gone up," not a correction to something said before. Actually, in the sense of "in fact" or as a correction, is na verdade.

Assistir means to watch, most commonly used for watching television or a film, not to assist or help. "Assisti ao jogo" means "I watched the game." To assist or help someone is ajudar.

Largo means wide or broad, not large in the sense of big overall. A largo can also be a small town square. Large, meaning big, is grande.

Three more that show up constantly in news and daily life

Recordar means to remember, not to record. "Ele recorda-se do acidente" means "He remembers the accident," not that he recorded it. To record something, audio or video, is gravar.

Realizar means to carry out or accomplish, not to realize in the sense of understanding something. "A empresa realizou o projeto" means "The company carried out the project." To realize, as in suddenly understanding, is aperceber-se or dar-se conta.

Costume means habit or custom, not a costume you wear. "Por costume, ele chega cedo" means "As a habit, he arrives early." A costume, the outfit, is fantasia, the word Brazilians also use for a Carnival costume specifically.

A worked example: one sentence, four traps

Take a single sentence you might actually see in a Portuguese news article: "Segundo o costume, o diretor assistiu à cerimónia e depois realizou uma pequena declaração aos parentes da vítima." Read with the English-shaped assumption, it looks like it might be saying the director "assisted" at a ceremony wearing a costume and then "realized" something about the victim's parents. Read correctly, it means: "As is customary, the director watched the ceremony and afterward gave a short statement to the victim's relatives." Nothing in that sentence is unusual Portuguese. It is only unusual if you're reading four false friends as if they were English words wearing a disguise.

A quick self-check for your own reading

You don't need to memorize this list defensively before you start reading. Use it as a live check instead:

  • When a sentence built from familiar-looking words still doesn't quite make sense, treat that as a signal about the word, not about your Portuguese.
  • Keep a running list of the false friends you personally trip over, not the full list above. The ones that cost you time are the ones worth drilling.
  • Reread the sentence once with the actual meaning substituted in. If it suddenly reads smoothly, you've found a false friend, not a comprehension gap.

Why these specific pairs happen

Most of these trace back to the same Latin roots as their English look-alikes, with the meaning drifting in one language and not the other over centuries. Puxar and "push" aren't actually related at all, that one is pure coincidental resemblance, which is exactly why it's dangerous: there's no shared history to half-remember correctly, just two unrelated words that happen to look like they should mean the same thing. Pretender and "pretend" do share a Latin root, praetendere, meaning roughly "to hold forth" or "to claim," and both languages kept a meaning close to "to claim something," but English narrowed toward claiming something false, while Portuguese kept the more neutral sense of claiming an intention.

Reading past them without stopping every time

The useful habit is the same one that works for any false friend: when a familiar-looking word makes a sentence stop making sense, that's the signal to reconsider the word rather than the sentence. A news article describing someone's parentes attending a funeral makes perfect sense once you know it means relatives broadly, and reads as a strange claim about someone's mother and father showing up if you don't. Keeping a short mental list of the pairs above, rather than trying to memorize all of Portuguese vocabulary defensively, catches most of the real damage these words do in ordinary reading.
