A aluna quer revisar a última lição antes da prova.

The first a is the definite article the. The second a is just the first letter of aluna.

So:

• a = the (feminine singular)
• aluna = female student

This is completely normal in Portuguese. It is not a typo, and there is no contraction here.

Aluna means female student. Portuguese nouns often show gender:

• aluno = male student
• aluna = female student

If you want a more gender-neutral word, Portuguese also uses estudante, which can refer to either a man or a woman.

Portuguese uses articles very often, sometimes more often than English.

In A aluna, the article a makes the noun specific: the student.

In many contexts, Portuguese sounds more natural with the article, especially when talking about a known person or thing.

Because after quer (from querer, to want), Portuguese normally uses the infinitive form of the next verb.

So:

• quer = wants
• revisar = to review

This is the same pattern as English wants to review.

Examples:

• Ela quer estudar. = She wants to study.
• Ele quer dormir. = He wants to sleep.

Quer is the present tense, third person singular, of querer.

Conjugation:

• eu quero = I want
• você / ele / ela quer = you / he / she wants
• nós queremos = we want
• eles / elas querem = they want

So A aluna quer... means The student wants...

Usually, yes, especially in a school context.

Revisar is very common in Brazilian Portuguese for:

• reviewing a lesson
• reviewing notes
• reviewing for a test

There is also rever, which can sometimes mean to review or to see again, but revisar is the more straightforward choice here for study material.

Because adjectives must agree with the noun in gender and number.

Here:

• lição is feminine singular
• so the adjective must also be feminine singular: última

Compare:

• o último livro = the last book
• a última lição = the last lesson

Not exactly.

• lição usually means lesson
• aula usually means class

So:

• a última lição = the last lesson/chapter/unit
• a última aula = the last class session

Depending on context, lição can also sometimes suggest schoolwork or a lesson in a textbook.

It breaks down like this:

• antes = before
• da = contraction of de + a
• prova = test / exam

So antes da prova literally means before the test or before the exam.

This contraction is very common in Portuguese:

• de + a = da
• de + o = do
• de + as = das
• de + os = dos

Because Portuguese commonly contracts certain prepositions with definite articles.

Here, antes is followed by de, and then you have the article a before prova:

• antes de a prova → antes da prova

This is the normal, natural form.

Yes. Prova can mean different things depending on context.

Common meanings include:

• test / exam
• proof / evidence
• sometimes competition or event

In a school sentence like this one, prova clearly means test or exam.

Because Portuguese often uses the definite article with specific nouns.

Here, a última lição means the last lesson, a specific lesson. That is why the article a is used.

Without the article, the phrase would usually sound less natural in this sentence.

The sentence uses a very common word order:

• A aluna = subject
• quer revisar = verb phrase
• a última lição = object
• antes da prova = time expression

This is natural and standard. But Portuguese does allow some flexibility.

For example, you could also say:

• Antes da prova, a aluna quer revisar a última lição.

That version puts more emphasis on the time phrase.

In Brazilian Portuguese, lição is pronounced roughly like lee-SOWN, but with a nasal ending.

A few key points:

• ç sounds like s
• ão is a nasal sound, very common in Portuguese
• the stress is on the last syllable: li-ÇÃO

A more accurate approximation is lee-SAHWNG, but nasal vowels do not match English exactly.

In Brazilian Portuguese, quer is pronounced roughly like kehr.

It is:

• one syllable
• usually with an open e sound
• not pronounced like English care, though that can be a rough memory aid for some learners

Yes. That would also be correct.

• aluna specifically says the student is female
• estudante can refer to either gender

So both are possible, but aluna is more specifically marked for gender.

You would change the article, noun, and sometimes the verb.

Examples:

• O aluno quer revisar a última lição antes da prova.
  = The male student wants to review the last lesson before the test.

• As alunas querem revisar a última lição antes da prova.
  = The female students want to review the last lesson before the test.

• Os alunos querem revisar a última lição antes da prova.
  = The students want to review the last lesson before the test.

Notice:

• quer = singular
• querem = plural
