How to Pronounce X in Portuguese – A Simple Guide for Leaners

LEVEL Open TOPIC Pronunciation consonants

Pronouncing the letter X in Portuguese can be tricky for language learners. That’s because, unlike in English, the letter X in Portuguese has four possible sounds:

  • /ʃ/ as in chave (key)
  • /ks/ as in táxi (taxi)
  • /z/ as in exemplo (example)
  • /s/ as in próximo (next)

Fortunately, some common spelling patterns can help you predict the correct pronunciation. Let’s dive in.

/ʃ/-sound

The most common pronunciation of the letter X in Portuguese is the /ʃ/ sound, similar to the English “sh” in she or ashes.

Words Starting with X

In European Portuguese, nearly all words that begin with X are pronounced with the /ʃ/ sound. Here are some examples:

0:00
  • xeque (check)
  • xarope (syrup)
  • xerife (sheriff)
  • xenofobia (xenophobia)
  • xícara (tea-cup)
  • . . .

X Before a Consonant

When the letter X appears before another consonant in Portuguese, it is almost always pronounced as /ʃ/.

Interestingly, many of these words have English cognates where the X is pronounced as /ks/ instead. Here are some examples:

0:00
  • texto (text)
  • explorar (explore)
  • extremo (extreme)
  • expectativa (expectation)
  • exterior (exterior)
  • . . .

X Between Vowels

When the letter X appears between vowels in Portuguese, things get a bit more unpredictable. There are three possible pronunciations, and unfortunately, no strict rules to follow.

For the most part, however, X between vowels is pronounced as /ʃ/—just like in previous cases. Here are some common examples:

0:00
  • baixo (short)
  • ameixa (plum)
  • queixa (complaint)
  • lixo (garbage)
  • puxar (pull)
  • . . .

As mentioned above, X can also take on other sounds in this position. Let’s explore those exceptions next.

/ks/-sound

In Portuguese, the letter X can be pronounced as /ks/ (like in accident) when it appears between vowels. Many of these words have English cognates that also follow the same pronunciation pattern.

Here are some common examples:

0:00
  • complexo (complex)
  • taxonomia (taxonomy)
  • fluxo (flux)
  • tóxico (toxic)
  • axioma (axiom)
  • . . .

/z/-sound

In some cases, the letter X in Portuguese is pronounced as /z/ (like in zealous). This often happens in words that have English cognates—although in English, the X is usually pronounced as /gz/ instead.

Here are some common examples:

0:00
  • exausto (exhaust)
  • exagero (exaggeration)
  • exílio (exile)
  • exame (exam)
  • exótico (exotic)
  • . . .

/s/-sound

In some rare cases, the letter X in Portuguese is pronounced as /s/ (like in sow). However, this pronunciation is an exception rather than the rule. Here are a few examples:

0:00
  • próximo (next)
  • máximo (maximum)
  • auxílio (help)
  • . . .

What learners say

I love the mix of formats. The listening pieces, short reads, exercises, and idioms cover different angles, so I don't get stuck doing the same thing. It keeps me coming back.

~ Olivia ~

It doesn’t feel like studying in the boring sense. The tone is light, but the practice is solid, and I’ve noticed I can put sentences together more easily.

~ Giulia ~

Everything feels well put together. I'll listen to something at my level, check a quick explanation when I'm confused, and then do a practice exercise. Everything I need is in one place and easy to find.

~ Liam ~

Portuguese used to feel messy, like I was putting in effort but not getting results. With Portuguesepedia, I can focus on what I actually need, and I’ve started noticing real improvement week by week.

~ Ebba ~

Something clicked after a few weeks. Real Portuguese started making more sense — not just on paper, but when I'm actually listening. I hadn't felt that kind of progress before.

~ Maria ~

I’d been trying to learn Portuguese for years, but I never felt confident using it. Textbooks were too much, and speaking classes made me freeze. With Portuguesepedia, things finally started to make sense.
