Minha meta é melhorar meu português.

Because meta is a feminine noun in Portuguese, so the possessive has to agree with it.

• meta = feminine singular
• so you use minha = my for feminine singular nouns

Compare:

• minha meta = my goal
• meu objetivo = my objective

A useful thing to remember: in Portuguese, possessives agree with the thing possessed, not with the speaker.

Yes. In this sentence, meta means goal, target, or aim.

In Brazilian Portuguese, meta is very common when talking about:

• personal goals
• work goals
• study goals
• fitness goals

Examples:

• Minha meta é estudar todo dia.
• A meta da empresa é crescer.

A close synonym is objetivo. In many situations, both work:

• Minha meta é melhorar meu português.
• Meu objetivo é melhorar meu português.

Meta can sound a little more like a concrete target, while objetivo can sound a bit broader, but in everyday use they often overlap.

Because after é, the sentence is defining what the goal is. In Portuguese, that is often done with the infinitive.

Structure:

• Minha meta = subject
• é = is
• melhorar meu português = the thing that the goal consists of

So literally, it works like:

• My goal is to improve my Portuguese.

Portuguese commonly uses the infinitive this way after ser:

• Meu sonho é viajar. = My dream is to travel.
• O importante é continuar. = The important thing is to continue.

So melhorar stays in the infinitive because it is not being conjugated as the main action of the sentence.

Yes, absolutely. That is grammatically correct.

Both are possible:

• melhorar meu português
• melhorar o meu português

In Brazilian Portuguese, people often omit the article before a possessive, especially in casual speech:

• meu português
• minha casa
• meu carro

But using the article is also very common:

• o meu português
• a minha casa
• o meu carro

In Brazil, article use with possessives is flexible. In this sentence, meu português sounds very natural.

In Portuguese, names of languages are normally written in lowercase.

So:

• português
• inglês
• espanhol
• francês

This is different from English, where you write Portuguese, English, and so on with capital letters.

You would only capitalize it if it begins the sentence:

• Português é uma língua muito falada.

Yes. Meu português literally means my Portuguese, referring to your ability in the Portuguese language.

This is very natural in both English and Portuguese. It means:

• your Portuguese skills
• your level of Portuguese
• the Portuguese you speak/use

So melhorar meu português means improving your command of the language, not changing the language itself.

Similar expressions:

• melhorar meu inglês
• melhorar meu espanhol
• melhorar minha pronúncia

É with an accent is the verb ser in the third person singular:

• ele é
• ela é
• você é

In this sentence, é means is.

The accent is important because without it, e is usually the word and.

Compare:

• é = is
• e = and

So:

• Minha meta é melhorar meu português. = My goal is to improve my Portuguese.
• Minha meta e melhorar... would be incorrect.

The accent in português shows the stressed syllable and is part of the correct spelling.

It is pronounced roughly like:

• por-tu-GUÊS

The ê marks a stressed vowel sound. This same pattern appears in some other nationality/language words:

• inglês
• francês
• japonês

Feminine forms also exist for nationalities:

• português = Portuguese man / Portuguese language
• portuguesa = Portuguese woman

But for the language, you use português.

Yes, it is completely natural.

Minha meta é melhorar meu português sounds like something a learner would really say. It is clear, correct, and idiomatic.

Other natural variations include:

• Meu objetivo é melhorar meu português.
• Quero melhorar meu português.
• Estou tentando melhorar meu português.

Your original sentence sounds a bit more deliberate and goal-oriented than simply saying Quero melhorar meu português.

Normally, no. That sounds unnatural in this case.

The best structure is:

• Minha meta é melhorar meu português.

After meta é, Portuguese normally goes straight to the infinitive when saying what the goal is.

You may see para in other structures, such as:

• Tenho uma meta para este ano.
• Estudo para melhorar meu português.

But with this exact pattern, é + infinitive is the natural choice.

Yes, depending on the nuance you want.

Common options:

• melhorar meu português = improve my Portuguese
• aprimorar meu português = refine/polish my Portuguese
• aperfeiçoar meu português = perfect/improve my Portuguese further

For most learners, melhorar is the most common and natural choice. It is simple, versatile, and very idiomatic.

Aprimorar and aperfeiçoar can sound a bit more formal or more advanced.

A helpful approximate pronunciation for an English speaker is:

min-ya MEH-ta eh meh-lyo-RAR meh-o por-too-GUES

A few notes:

• minha often sounds close to min-ya
• melhorar has the lh sound, similar to the lli in million for many learners
• meu often sounds like meh-o or almost myoo, depending on the speaker
• português is stressed on the last syllable: -guês

If you want to sound more Brazilian, keeping the stress right is especially important:

• MI-nha
• ME-ta
• melho-RAR
• portu-GUÊS

Yes.

All of these are correct:

• Minha meta é melhorar meu português.
• A minha meta é melhorar meu português.
• Meu objetivo é melhorar meu português.
• O meu objetivo é melhorar meu português.

In Brazilian Portuguese, using or omitting the definite article before a possessive is often a matter of style, rhythm, or regional preference.

So:

• Minha meta... = very natural
• A minha meta... = also natural, sometimes slightly more explicit or emphatic

For a learner, the article-free version is a very safe and common choice in Brazil.
