O prazo do projeto termina na quinta-feira, então meu tio vai revisar tudo hoje.

Do is the contraction of de + o, so o prazo do projeto literally means the deadline of the project.

Portuguese often uses a de phrase where English prefers a noun-noun combination:

• project deadline → prazo do projeto
• car door → porta do carro

Also, Portuguese usually includes the definite article here, so de + o = do is very common.

Prazo means deadline, time limit, or due date, depending on context.

In this sentence, o prazo do projeto is basically the project deadline.

A useful detail: Portuguese often says that a deadline ends or expires, so o prazo termina is a very natural way to express that the deadline is on a certain day or reaches its end then.

Portuguese, like English, can use the present tense for a scheduled or certain future event.

So:

• O prazo termina na quinta-feira = The deadline ends on Thursday

This is similar to English sentences like:

• The meeting starts at 9 tomorrow
• My flight leaves on Friday

You could also use a future form in Portuguese, but the present is very natural here.

Na is the contraction of em + a.

• em a quinta-feira → na quinta-feira

Weekday names such as segunda-feira, terça-feira, quarta-feira, quinta-feira, and sexta-feira are feminine because of feira, so they normally combine with a.

So:

• na quinta-feira = on Thursday

This is a very common pattern in Brazilian Portuguese.

Yes. In Brazilian Portuguese, it is very common to shorten the weekday name:

• na quinta-feira
• na quinta

Both mean on Thursday. The shorter version is more casual and very common in speech.

Here, então means so, therefore, or in that case.

In this sentence, it connects the two ideas:

• the deadline is Thursday
• so my uncle is going to review everything today

So então is showing a consequence or result.

The comma separates two related clauses and makes the logic clearer.

• O prazo do projeto termina na quinta-feira, então meu tio vai revisar tudo hoje.

This is similar to English punctuation before so in a sentence joining two full ideas. In writing, the comma is very natural here.

Vai revisar is the very common ir + infinitive future structure.

• vai = present tense of ir
• revisar = infinitive

So:

• vai revisar = is going to review / will review

This is one of the most common ways to talk about the future in Brazilian Portuguese.

A more formal or literary alternative would be revisará, but vai revisar is much more common in everyday language.

In this context, revisar usually means to review, to check, or to go over something.

This can be tricky for English speakers because revise in English can mean different things depending on the variety of English. In Brazilian Portuguese, revisar often suggests checking for mistakes, correcting, or looking over something carefully.

So here, meu tio vai revisar tudo most likely means my uncle is going to review/check everything.

In Brazilian Portuguese, possessives can appear with or without the article:

• meu tio
• o meu tio

Both are possible. In Brazil, leaving out the article is very common, especially in everyday speech. Using the article can sound a bit more specific, regional, or stylistically different depending on the speaker.

So meu tio is completely natural.

Tudo means everything.

• revisar tudo = review everything

Todo usually works differently. It often means every or all, and it normally goes with a noun:

• todo o projeto = the whole project
• todas as páginas = all the pages

So here, because the idea is everything, the correct word is tudo.

Yes, hoje can move around. Portuguese has fairly flexible adverb placement.

These are all possible:

• Meu tio vai revisar tudo hoje
• Hoje meu tio vai revisar tudo
• Meu tio hoje vai revisar tudo

The version in the sentence sounds very natural because hoje comes after the main action and gives the time information at the end. It is a common, neutral word order.

Yes. In the second clause, meu tio is the subject:

• meu tio = subject
• vai revisar = verb phrase
• tudo = object
• hoje = time expression

So the structure is:

my uncle + is going to review + everything + today

That word order is very standard in Portuguese.
