Tu falas bem português?

In European Portuguese, tu is the common informal singular you, especially with friends, family, children, and in many everyday situations.

• tu falas = informal you speak
• você fala = more formal or more distant you speak

A learner should know that você exists, but in Portugal it is often used less than English speakers expect. Very often, people either use tu or avoid the pronoun altogether and just use the verb form.

Because the verb has to agree with tu.

The infinitive is falar = to speak.
In the present tense:

• eu falo = I speak
• tu falas = you speak
• ele/ela/você fala = he/she/you speak

So falas is the correct present-tense form for tu.

Yes. Portuguese often drops subject pronouns when the verb already makes the subject clear.

So both of these are natural:

• Tu falas bem português?
• Falas bem português?

In conversation, the version without tu is very common.

Bem means well, and it usually comes after the verb it modifies.

So:

• falas bem = speak well

Then português tells you what language is being spoken:

• falas bem português = you speak Portuguese well

This order is normal in Portuguese.

Portuguese does not use a helper verb like English do to form most questions.

English:

• Do you speak Portuguese well?

Portuguese:

• Tu falas bem português?

A statement and a yes/no question can have the same word order. The question is shown by:

• intonation in speech
• the question mark in writing

Usually no. In Portuguese, names of languages are normally written with a lowercase letter.

So:

• português
• inglês
• francês

This is different from English, where Portuguese must be capitalized.

After verbs like falar when talking about languages in a general way, Portuguese often uses the language name without an article.

So:

• Falo português.
• Falamos inglês.

Using o português is possible in some contexts, but in this sentence the most natural basic form is simply português.

A simple learner-friendly approximation is:

• tu ≈ too
• falas ≈ FAH-lush or FAH-lahs depending on the speaker
• bem ≈ sounds a bit like beng with a nasal ending
• português ≈ por-too-GESH in European Portuguese

A few important points:

• European Portuguese often reduces unstressed vowels.
• The final -s in falas is often pronounced like sh in Portugal.
• bem has a nasal sound, not a clear English m.
• In português, the stressed syllable is the last one: -guês.

This is a very common question.

• bem = well → adverb
• bom = good → adjective

In this sentence, we need an adverb because it describes how someone speaks:

• Tu falas bem português? = Do you speak Portuguese well?

Not:

• Tu falas bom português? in the sense of well

However, bom português can exist with a different meaning, like good Portuguese as a noun phrase:

• Ele escreve bom português. = He writes good Portuguese.

Yes, it is natural and correct. But there are a few other common ways depending on what exactly you want to ask:

• Tu falas português? = Do you speak Portuguese?
• Falas bem português? = Do you speak Portuguese well?
• Sabes falar português? = Do you know how to speak Portuguese?
• Consegues falar português? = Can you manage to speak Portuguese?

Your sentence is specifically about speaking it well.

Not always in every social situation, but it is extremely common and very important to learn for European Portuguese.

Use tu with:

• friends
• relatives
• classmates
• many coworkers
• children
• people your age in informal situations

In more formal situations, people may:

• use você
• avoid the pronoun and use a formal verb form
• use titles such as o senhor / a senhora

So Tu falas bem português? is natural in an informal context.

It is the present indicative.

In this sentence, it usually means:

• Do you speak Portuguese well? or
• You speak Portuguese well? depending on context and intonation

The present tense in Portuguese often covers the same basic situations as the English present simple.

It is understandable, but Tu falas bem português? is more natural in this context.

Placing bem right after the verb is the most straightforward way to say speak well:

• falas bem português = natural
• falas português bem = possible, but less neutral and less common as a default phrasing

So for learners, Tu falas bem português? is the best model to follow.
