Răspunsul este adevărat.

Because Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the.

• răspuns = answer
• răspunsul = the answer

This is called the enclitic definite article. For many masculine and neuter singular nouns, the definite article is -ul.

Răspuns is a neuter noun in Romanian. Neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

So in the singular, it takes forms like a masculine noun would. That is why the adjective is adevărat, the same form used for masculine singular.

Because adevărat must agree with răspunsul in number and, effectively here, in gender.

Common forms of the adjective are:

• masculine / neuter singular: adevărat
• feminine singular: adevărată
• masculine plural: adevărați
• feminine / neuter plural: adevărate

Since răspunsul is singular and neuter, the correct form is adevărat.

Este means is. It is the 3rd person singular of a fi = to be.

So:

• Răspunsul este adevărat. = The answer is true.

In everyday Romanian, este is sometimes omitted in very informal speech or special styles, but in standard, clear Romanian, you should keep it here.

Yes. E is the shorter, very common form of este.

So both are correct:

• Răspunsul este adevărat.
• Răspunsul e adevărat.

The version with este may sound a bit more careful or formal, while e is extremely common in everyday speech.

This is the most neutral and natural word order:

• subject: Răspunsul
• verb: este
• predicate adjective: adevărat

Romanian word order is fairly flexible, so other orders can appear for emphasis, but the basic learner-friendly version is exactly this one.

For example, Adevărat este răspunsul would sound marked or literary, not like the normal everyday choice.

A simple English-friendly guide is:

ruh-SPUN-sool YES-teh ah-deh-vuh-RAHT

A few important points:

• ă is a short neutral vowel, similar to the a in about
• â in adevărat is a deeper central vowel, somewhat like a tense, darker uh
• stress:
  • răSPUNsul
  • ESte
  • adevăRAT

This is only an approximation, but it helps you get close.

Because Romanian usually expresses the by attaching it to the end of the noun.

Compare:

• English: the answer
• Romanian: răspunsul

This is one of the big structural differences between Romanian and English. Learners often expect a separate article, but Romanian usually uses a suffix instead.

Yes, adevărat can mean true and sometimes real/genuine, depending on context.

Examples:

• E adevărat. = It is true.
• un prieten adevărat = a true / genuine friend

In Răspunsul este adevărat, the natural meaning is true, because it describes whether the answer is correct or truthful.

Sometimes, but not always.

• adevărat = true
• corect = correct

If you are talking about whether a statement matches reality, adevărat is the natural word. If you are talking about whether an answer is right on a test, corect may also fit.

So:

• Răspunsul este adevărat. = The answer is true.
• Răspunsul este corect. = The answer is correct.

English sometimes overlaps these ideas, but Romanian may choose different adjectives depending on the situation.

Yes. It is grammatically complete and natural.

It has everything it needs:

• a subject: Răspunsul
• a verb: este
• a complement describing the subject: adevărat

It sounds like a normal standard Romanian sentence.

The indefinite version would be:

Un răspuns este adevărat.

That means An answer is true.

Compare:

• răspuns = answer
• un răspuns = an answer
• răspunsul = the answer

So the original sentence is definite because it refers to a specific answer.
