A informação está correta.

In Portuguese, it is very common to use the definite article with nouns when talking about a specific thing already being discussed or understood from context.

So A informação está correta most naturally means The information is correct.

If you say just Informação está correta, it sounds incomplete or unnatural in normal Portuguese.

A few useful comparisons:

• A informação está correta. = The information is correct.
• Essa informação está correta. = That information is correct.
• Uma informação correta... = A correct piece of information...

Informação is a feminine noun, so it takes:

• the feminine article a
• the feminine form of the adjective correta

That is why you get:

• a informação
• correta

A helpful pattern: many nouns ending in -ção are feminine in Portuguese:

• a informação
• a situação
• a tradução
• a solução

So once you recognize -ção, feminine agreement often becomes easier to predict.

Portuguese often uses estar for a current state or condition, and ser for identity, definition, or more permanent characteristics.

Here, está correta means the information is correct in this case, at this moment, or according to the current evaluation.

• A informação está correta. = The information is correct.
• A informação é correta. = possible, but less natural here; it can sound more like the information is correct by nature / proper / accurate as a general characterization

In everyday Portuguese, when checking whether some information is right or wrong, está correta is the normal choice.

Está is the third-person singular present tense of the verb estar.

The subject is a informação, which is singular, so the verb must also be singular:

• A informação está correta.

Other forms of estar in the present:

• eu estou
• você/ele/ela está
• nós estamos
• vocês/eles/elas estão

So if the noun changes, the verb changes too:

• As informações estão corretas. = The information / the pieces of information are correct.

Because adjectives usually agree with the noun they describe in gender and number.

Here:

• informação = feminine singular
• so the adjective must also be feminine singular: correta

Agreement pattern:

• correto = masculine singular
• correta = feminine singular
• corretos = masculine plural
• corretas = feminine plural

Examples:

• O documento está correto.
• A informação está correta.
• Os documentos estão corretos.
• As informações estão corretas.

Sometimes yes, but they are not always exactly the same.

• correta usually means correct / accurate
• certa can mean right / correct, but it can also mean certain, specific, or the right one

In this sentence, A informação está correta is the safest and clearest way to say The information is correct.

Compare:

• A informação está correta. = The information is accurate.
• A informação certa = the right/correct information

So certa often works, but correta is more precise for factual accuracy.

Yes. Informação can work much like information in English, as a mass noun in the singular.

• A informação está correta. = The information is correct.

But Portuguese also very naturally uses the plural informações when talking about separate items or pieces of information:

• As informações estão corretas. = The pieces of information are correct / The information is correct.

So both singular and plural are common, depending on whether you are thinking of it as a whole or as multiple details.

Yes, Está correta a informação is grammatically possible, but it sounds more marked or emphatic.

The neutral, standard order is:

• A informação está correta.

A reversed order like:

• Está correta a informação.

may sound more literary, emphatic, or context-driven, as if contrasting with something else.

For most learners, the normal order subject + verb + adjective is the best choice.

A simple approximation is:

• in-for-ma-SOWN

But there are a few important details:

• the stress falls on the last syllable: -ÇÃO
• ão is a nasal sound, not an English ow
• the ç sounds like s
• the final syllable is something like a nasal sown/song blend, depending on accent

A rough learner-friendly breakdown:

• in-for-ma-SÃO

Not perfect, but useful at first.

The accent marks show where the stress goes and sometimes help distinguish words.

• informação → stress on the last syllable: ção
• está → stress on the second syllable: tá

Without the accent, the reader might stress the word differently or confuse it with another form.

For example:

• esta = this
• está = is

So the accent in está is very important.

Just put não before the verb:

• A informação não está correta. = The information is not correct.

This is the normal way to make a negative sentence in Portuguese.

You can also say:

• A informação está incorreta. = The information is incorrect.

Both are correct, but they are slightly different in style:

• não está correta = not correct
• está incorreta = incorrect

You need to change the article, noun, verb, and adjective so everything agrees:

• A informação está correta. = singular
• As informações estão corretas. = plural

Breakdown:

• a → as
• informação → informações
• está → estão
• correta → corretas

Portuguese agreement is very consistent, so once you spot the noun’s gender and number, the rest usually follows.

Yes. In this sentence, correta is a predicate adjective, not an adjective directly attached to the noun.

So the structure is:

• A informação = subject
• está = linking verb
• correta = adjective describing the subject

This is similar to English:

• The information is correct.

If the adjective comes directly before or after the noun, the structure changes:

• a informação correta = the correct information

So compare:

• A informação está correta. = The information is correct.
• A informação correta... = The correct information...

That is an important difference in Portuguese.
