A licença médica termina amanhã.

A is the feminine singular definite article, meaning the.

It is used here because licença is:

• feminine
• singular
• referring to a specific medical leave that both speakers can identify

So A licença médica = the medical leave / the sick leave.

Usually, no. In this sentence, licença médica means medical leave, sick leave, or leave from work/school for health reasons.

This is a good false-friend warning for English speakers:

• licença can sometimes mean license in other contexts
• but licença médica normally means a period of authorized absence for medical reasons

So here it is about time off, not a professional permit.

Because médica is an adjective describing licença, and adjectives usually agree with the noun in gender and number.

• licença = feminine singular
• so the adjective must also be feminine singular → médica

If the noun were masculine, you would use médico instead.

In Portuguese, adjectives often come after the noun, much more often than in English.

So:

• licença médica literally follows the pattern leave medical

This is a very normal word order in Portuguese. Some adjectives can come before the noun, but in expressions like this, the post-noun position is the standard one.

Termina is the conjugated verb form. Terminar is the infinitive, meaning to end.

Here the subject is A licença médica, which is third person singular, so the verb becomes:

• eu termino
• você/ele/ela termina
• a licença médica termina

So termina means ends.

Portuguese often uses the present tense to talk about a near or scheduled future, especially when there is a time word that makes the future meaning clear.

Here, amanhã already shows that the event happens in the future, so termina sounds natural.

This is similar to English sentences like:

• My trip ends tomorrow
• The class starts tomorrow

So even though the verb is in the present form, the meaning is future.

Yes. That is also correct.

• A licença médica termina amanhã = simple, natural, common
• A licença médica vai terminar amanhã = also natural, a little more explicitly future

Both are fine in Brazilian Portuguese. The first one is often more concise.

Yes, in many situations you could say:

A licença médica acaba amanhã.

That would also sound natural.

In general:

• terminar = to end, to finish
• acabar = to end, to be over, to come to an end

In this sentence, the difference is small. Termina may sound slightly more neutral or formal, while acaba is also very common in everyday speech.

Amanhã means tomorrow.

The stress is on the last syllable:

• a-ma-NHÃ

A few pronunciation notes:

• nh sounds like the ny sound in canyon
• ã is nasal, so the vowel is pronounced through the nose

So it sounds roughly like ah-ma-NYAHN, with a nasal ending.

The mark over ã is a tilde, and it shows that the vowel is nasal.

So ã is not just a normal a. You pronounce it with nasal resonance.

In amanhã, the tilde helps signal both pronunciation and stress pattern. It is an important part of the spelling.

The most neutral order is:

A licença médica termina amanhã.

That is:

• subject: A licença médica
• verb: termina
• time expression: amanhã

You could move amanhã for emphasis, for example:

• Amanhã a licença médica termina.

But that sounds more marked or emphatic. The original version is the most natural default sentence.

Most often, licença médica refers to the leave itself, the period when someone is officially away for medical reasons.

If you want to refer specifically to the doctor’s note or certificate, Brazilian Portuguese often uses:

• atestado médico

So:

• licença médica = medical leave / sick leave
• atestado médico = medical certificate / doctor’s note

Most of the time, yes. A licença médica sounds natural and standard.

Portuguese uses definite articles more often than English does. In a sentence like this, leaving out the article would usually sound unnatural unless it were part of a special headline, note, or highly reduced style.
