How to Pronounce ão in Brazilian Portuguese: the Nasal Sounds

Say pão the way English wants to say it and you get “pown,” with the tongue rising at the end to close the word off. That closure is the mistake. There is no n at the end of ão, and no ng either. The vowel starts where the ow in “how” starts, your lips round toward an o, and the air leaves through your nose while your mouth is still open. Nothing shuts. Fix that one habit and não, pão and mão land where a Brazilian expects them.

The nose test, in thirty seconds

Put your fingertips lightly on the bridge of your nose and say the English word “no” and hold the vowel at the end. Nothing moves under your fingers. All of the air is leaving through your mouth.

Now say não and hold the end of it. You should feel a buzz travel up into your nose. That buzz is the sound. If your fingertips stay still, the nasal is not engaging yet, and saying the word louder will not change that.

What changes is a flap at the back of your mouth, the soft palate. For an English vowel it stays raised and seals the nose off. For a Portuguese nasal vowel it drops, and the air runs through your nose and your mouth at once. The route the air takes is the whole sound.

The sound English speakers add by reflex

English has nasal consonants (m, n, ng) and no nasal vowels at all. So when your ear meets a nasal vowel, your mouth reaches for the closest thing it owns: a vowel followed by a consonant. That is where “pown” comes from. The vowel is roughly right and then the tongue rises to the roof of the mouth and shuts the word.

Feel the difference on purpose. Say the English word “own” and notice your tongue landing on the ridge behind your top teeth. Now say pão and keep that tongue on the floor of your mouth from the first millisecond to the last. The word has to end with your mouth still open and the buzz still running.

One thing does close, and it is easy to confuse with the mistake. Our course material tells you to bring your lips almost shut as you finish an ão, which is what rounds the sound toward an o and gives it that trailing w. Lips round. The tongue never touches anything. Keep those two apart and the sound is yours.

ão: the one you meet first

ão is the most common nasal in Brazilian Portuguese, and it sits in some of the most frequent words in the language. Start where the ow in “how” starts, round your lips toward an o, and send it through your nose. It is one syllable. Unless the word carries a written accent somewhere else, an -ão at the end of a word takes the stress.

Two of those words hide a second sound. In coração the R between vowels is a quick tap, close to the tt in American “butter,” and in irmão the R before a consonant is closer to an H. The tap has its own drill in our guide to the Brazilian R, position by position.

ã: the nasal that holds and stops

Written with a tilde and nothing after it, ã is the same nasal engine without the trailing w. ão glides toward a w and dies away. ã holds the nasal and stops.

Say não and then lã back to back. The first one glides. The second one parks. Same nose, different exit.

ãe and õe: two nasals in one syllable

Some words carry two nasal vowels glued together with no pause between them. Your lips start open and end nearly closed, and the whole thing vibrates through your nose from beginning to end. ãe is a nasal a gliding into a nasal i. õe is a nasal o gliding into that same i.

Both show up most often in plurals, which is where an -ão word changes shape. Most go to -ões (canção becomes canções), a small group goes to -ães (pão becomes pães), and a few add an s (mão becomes mãos). Which group a word belongs to is vocabulary you pick up over time, and the sound is always one of the nasals you are training here.

bem, bom, com: the M you never say

When a Portuguese word ends in -em, -en, -om or -on, that final letter is not a consonant. It is a note on the page telling you to nasalize the vowel in front of it. English speakers hear the M coming and press their lips together for it. The lips stay apart.

The -em words finish with the same i-like glide you met in mãe, which is why bem lands closer to BEY~ than to BEH~. The -om words are simpler: one closed o, nasalized, and out. Drill também first, since both of its syllables are nasal and neither one has an M in it when you say it.

That second one packs two of Brazil’s signature habits into two words. The soft opening in dia is the palatalization covered in our guide to T and D before an i sound, and it hides at the end of hundreds of words the same way the nasal does.

The -am ending hiding on your verbs

In these respellings ow~ is always the vowel of “how”: FAH-low~ rhymes with “cow,” not with “slow.” Here is the payoff for grammar. A written -am at the end of a Portuguese verb has nothing to do with the English word “am.” It follows the same rule as bem and bom: the M is not said, the vowel nasalizes, and what comes out is the ão sound sitting on an unstressed syllable.

Once you see it, the entire they-column of the verb system turns nasal. Present tense gives you falam and cantam on one side and vivem and comem on the other. The past keeps it going with falaram and comeram. If you have been saying those endings with an English m, every plural verb you own has been carrying a consonant that Brazilians do not hear in it.

When the nose decides the word

This is the reason the nasal earns training time instead of a mental footnote. In a handful of everyday words, the nose is the only thing standing between one meaning and another.

Read the respellings side by side and you can see how little separates them: mau is MOW and mão is MOW~. One tilde apart, and one of them is a hand while the other calls someone bad. Ask a bakery for pau and you have asked for a stick.

The last row works a little differently. Vou and vão differ by more than the nose, so it is not a pure pair. At conversation speed, though, the nasal is the fastest thing your ear can grab, and it is the difference between what you are doing and what they are doing.

What nasals do to your listening

Your ear hunts for consonants. They are the edges it uses to cut a stream of speech into words. A nasal vowel gives it none, which is why the smallest and most frequent words in Portuguese are the ones that slip past you.

Não is the expensive one. In fast speech it can shrink almost to a hum, and in front of a verb Brazilians often say num instead: num sei for não sei. Miss it and you have not missed a word, you have missed the negation, and the sentence you walk away with means the opposite of what was said.

Também behaves the same way. You are waiting for a crisp final M that never arrives, so the word never registers. Então works as a sentence opener and reaches you as a soft nasal ramp rather than a clear consonant.

Cê in that line blurs for a different reason. It is você compressed, one of the reductions in our guide to spoken Portuguese contractions. Nasals and reductions are what stand between the Portuguese you can read and the Portuguese arriving at your ear.

Common mistakes English speakers make

Every one of these comes from mapping a Portuguese nasal onto the nearest English shape. The fix is the same each time: check whether anything closed at the end.

• pão said as “pown”

  pão said as POW~

  The tongue rising at the end is an English habit, not part of the word. Round the lips toward an o and let the sound end with your mouth open and the air still moving through your nose.

• não said with an ng at the end

  não said as NOW~

  The N at the front is a real consonant and the one at the end does not exist. If you can feel the back of your tongue touch anything, the word has a consonant Brazilians never put there.

• também said as TAM-BEM with a crisp M

  também said as ta~-BEY~

  Both syllables are nasal and neither one closes on the lips. The M on the page is the instruction to nasalize, and the ending glides toward an i.

• mãe said like the English “may”

  mãe said as MY~

  The vowel starts open and glides toward an i, so the target is the English “my” through the nose. Landing on “may” takes you to a different vowel and drops the nasal along the way.

• falam ending in the English “am”

  falam ending in the same nasal as pão

  The they-form of an -ar verb ends on the ão sound, unstressed. Say the M and every plural verb you produce carries a consonant that is not in the word.

• mão and mau said the same way

  mão through the nose, mau through the mouth

  One is a hand and the other means bad. The nose is the only difference, so it is worth ten minutes of drilling on its own.

The drill set

Fingertips back on the bridge of your nose. Read each line slowly enough to feel a buzz on every nasal, then again at the speed you would use with a friend. If a buzz goes missing at speed, that word goes back to slow.

Then run the pairs: pão and pau, mão and mau, lã and lá. When the nasal arrives without you planning it, the habit is built.

Quick recap

Five points to keep.

Nasals are the most distinctly Brazilian part of the sound system and the category our course material treats as the hardest to build, because English gives you nothing to borrow from. What makes them worth the hours is that the fix is one habit: stop closing the end.
