Hi everyone, how’s it going? Well, in today’s Dica, you will learn how to pronounce the letter X in Portuguese. Some letters might look difficult in Portuguese because of accents and pronunciation but don’t worry! We are here to help you out, even with the X-sound in Portuguese!

Letter X in Portuguese

Many foreigners are initially afraid of pronouncing the portuguese X, but it doesn’t need to be difficult. This happens because, depending on the word, the X can have different sounds. And as you already know, we have a lot of exceptions in Portuguese, so of course this also happens with the letter X. But let’s learn the sounds one by one so you won’t get confused anymore.

X in Portuguese: Sound of CH

The X can have the same sound that in English SH makes (a quite common sound for the carioca accent), like when you silence someone “Shhhhhh”. So now we will see in which cases this happens. Check it out:

After a Diphthong

Diphthong is the meeting of two vowels that belong to the same syllable and are pronounced in a single continuous sound. So, when we have the letter x in Portuguese followed by a diphthong, the sound will be like shhhhh. Check out the examples:

A ameixaThe plum
A faixaThe ribbon
BaixoLow / Short
DeixarLeave / Let
A caixaBox

After EN

Another instance where the X sounds like shhhhh is when it is preceded by the syllable EN. Check out the examples below:

A enxadaThe hoe (gardening tool)
O enxameThe swarm
O enxovalThe trousseau
EnxaguarTo rinse


You’ve already studied a lot of Portuguese with our online classes, right? So, you know that Portuguese has lots of exceptions and exceptional cases. With the Portuguese X it’s no different.  Check out special cases where the letter X still makes the SH sound:

OxaláI hope so / Divinity of Afro-Brazilian religions
MexerTo move something / interfere

Some other exceptions to this rule are the words: lixo (garbage), puxar (pull), xícara (cup). And if the word starts with an X the sound will be SH too.

X in Portuguese: Sound of Z

So here we move on to another sound: X equals Z. The letter X in Portuguese can also have a ZZZZZ sound. It usually occurs when the X is between two vowels. Let’s look at some examples:

O êxodoThe exodus
O exameThe exam
O exercícioThe exercise
A execuçãoThe execution
O exércitoThe army
O exílioThe exile

So, there you have it, when the X lies between two vowels, it sounds like the Z.

X in Portuguese: Sound of S, SS and SC

two people hang gliding in rio de janeiro. example of x in the word experiência in portuguese. headline: "como será a experiência de voar de asa delta?"

Did you think it was over? No, no, no! The Portuguese x can still sound like an S, SS and SC. Let’s see what happens in each case.

X with the sound of S

When the X is before P, it sounds like S. Check out:

ExpressarTo express
A experiênciaExperience

When the X  is before T, the sound is also like S:


X with the sound of SC

When the X is before C, it sounds like SC:

A exceçãoException

X with the sound of SS

If we have the X after AU, it will sound like double S:


Of course, we have some words that don’t follow these rules like: próximo (next), and máximo (maxim).

X in Portuguese: Sound of KS

seven friends hanging out at the beach under the hot sun of rio de janeiro. example of use for the x in the word fixo. headline: "a praia é o nosso ponto fixo de encontro!"

Well, here we go with another X, but this time with the sound of KS. Here we don’t have a specific rule. Can you notice the sound of the KS? It’s happens with a lot of words that come from the English language, or Latin too. Let’s see here some words like this:

I’ve just started online classes with Prof. Ana Carolina & she is the absolute best! It’s my first time learning Portuguese and I was speaking full sentences in the first class. Obrigada!

Small classes, diverse accents, and engaging professors make Rio & Learn Online a fantastic choice! I've been thrilled with my experience at Rio & Learn Online so far. The small class sizes (around 1-3 others students) allow for personalized attention and plenty of opportunities to practice speaking. What's more, having different professors throughout the program exposes you to various accents, preparing you for real-world interactions. I opted for the full-time program, which involves 2 hours of daily learning from Monday to Friday. After just over 12 weeks, I can confidently say my Portuguese has improved dramatically. The professors are incredibly engaging and encourage students to utilize real-life examples, solidifying the learning process. While I'm only halfway through the program, I'm confident in recommending Rio & Learn Online to anyone seeking to learn Portuguese in a supportive and effective environment. I've gone from being a complete beginner (only knowing hi and bye) to holding conversations - and I'm excited to see how much further I can progress! I'll be back with another review after completing the program, but for now: Rio & Learn Online - highly recommended!

Après 3 semaines que je suis dans cette école et je peux déjà parler portugais. Certe avec des erreurs mais j'ai fait des progrès fulgurant. En plus, du Lundi au Vendredi l'ecole propose des activitées qu'il appelle "Rio Live" ce qui permet de visiter en même temps Rio tout en parlant Portugais et de rencontrer des gens😃 Toute l'équipe est genial et est prêts à aider si besoin 😁
I've been taking the group online courses with Rio&Learn for 2 months. They offer a fantastic way to learn Portuguese and get speaking practice if you don't live in Brazil. The teachers are engaging and are able to adjust their level of Portuguese to whatever level you are at. Obrigado!

C'est vraiment fantastique...RioAndLearn. Les cours de portugais...ça vaut vraiment la peine. Les cours ont lieu du lundi au vendredi, (de 9h à 13h) et en après midi, ce sont des activités libres en groupe. (Soccer de plage, volleyball , excursions, visites des lieux touristiques, etc) Vendredi soir, on est allé à Lapa, un quartier nocturne de Rio. C'est quelque chose à voir! Des rues bondées de monde, des orchestres, des discothèques...Allô les décibels! L'apprentissage du portugais se fait en immersion, aussi bien en salle de classe que dans les activités extérieures organisées par Rio&Learn. On est plongé dans la langue portugaise et la culture Brésilienne.... Obligé de parler portugais....🫡 Je le recommande. Pierre Pedro, Montréal, Canada
