Secvența este corectă.

Because secvența is the definite form of the noun.

In Romanian, the definite article is usually attached to the end of the noun instead of being a separate word like the in English.

• secvență = a sequence
• secvența = the sequence

So the sentence is using the sequence, not just a sequence.

Yes. Secvență is a feminine singular noun.

That matters because adjectives in Romanian usually have to agree with the noun in gender and number. Since secvența is feminine singular, the adjective also appears in the feminine singular form:

• masculine singular: corect
• feminine singular: corectă

That is why the sentence says corectă, not corect.

The ending -ă marks the adjective as feminine singular.

Romanian adjectives change form to match the noun they describe. Here the noun is secvența, which is feminine singular, so the adjective must match it:

• un răspuns corect = a correct answer (masculine singular)
• o secvență corectă = a correct sequence (feminine singular)

So corectă is simply the agreement form required by secvența.

Este is the 3rd person singular form of the verb a fi, meaning to be.

So:

• este = is

In this sentence, it links the subject secvența with the adjective corectă.

Romanian often also uses the shorter spoken form e:

• Secvența este corectă.
• Secvența e corectă.

Both are correct. Este sounds a bit more neutral or formal, while e is very common in everyday speech.

Yes. That is completely natural Romanian.

• este = full form
• e = shorter everyday form

Both mean the same thing here. In writing, especially more careful or formal writing, este may be preferred. In conversation, e is extremely common.

These are two important Romanian letters.

• ț is pronounced like ts in cats
• ă is a short central vowel, similar to the a in about or sofa, but shorter and clearer

So roughly:

• secvența ≈ sek-վեն-tsa / more precisely sek-VEN-tsa
• corectă ≈ ko-REK-tuh, with the final ă as a short unstressed vowel

The stress usually falls like this:

• secVENța
• coRECtă

Yes, it can change, but this is the most neutral and standard order:

• subject + verb + adjective/complement

So:

• Secvența este corectă. = the normal, unmarked way to say it

Romanian word order is more flexible than English, so you may also hear:

• Corectă este secvența.

But that sounds more marked or emphatic, as if you are emphasizing correct. For a learner, the normal order Secvența este corectă is the safest choice.

Normally, no. In standard Romanian, you usually keep the verb a fi in sentences like this.

So:

• Secvența este corectă. = correct
• Secvența corectă. = not a normal complete sentence in this context

Without este, secvența corectă would usually be understood as a noun phrase meaning the correct sequence, not a full statement meaning the sequence is correct.

Here, corectă is an adjective.

It describes the noun secvența and functions as a predicate adjective after the verb este.

Compare:

• o secvență corectă = a correct sequence
  Here the adjective is directly inside the noun phrase.

• Secvența este corectă. = The sequence is correct.
  Here the adjective comes after este and describes the subject.

So it is still an adjective in both cases; only its position and function in the sentence are different.

It is neutral overall.

• Secvența is a normal standard word.
• este makes it slightly more careful or formal than e, but not especially formal.
• corectă is also neutral standard Romanian.

So the whole sentence sounds perfectly normal in standard written or spoken Romanian.

Not always. It depends on context.

Secvență is a valid and common Romanian word, especially in technical, academic, cinematic, or structured contexts. But depending on what kind of sequence you mean, Romanian might also use other words in other contexts.

Still, in this sentence, secvența este corectă is completely natural Romanian.

Then the adjective would change to match it.

For example:

• Răspunsul este corect. = The answer is correct.
• Secvența este corectă. = The sequence is correct.

Compare the adjective endings:

• masculine singular: corect
• feminine singular: corectă

This is a very important pattern in Romanian: adjectives usually agree with the noun’s gender and number.

It is singular.

You can tell from both the noun and the adjective:

• secvența = singular definite feminine
• corectă = feminine singular adjective

If it were plural, the sentence would look different:

• Secvențele sunt corecte. = The sequences are correct.

So this sentence is clearly about one sequence.
