Punctul este important.

Because -ul is the Romanian definite article attached to the end of the noun.

• punct = point
• punctul = the point

Unlike English, Romanian usually puts the at the end of the noun instead of before it.

A few similar examples:

• băiat = boy → băiatul = the boy
• loc = place → locul = the place

So in this sentence, punctul specifically means the point, not just a point.

Yes. Punct is a neuter noun in Romanian.

That matters because Romanian neuter nouns behave:

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

So in the singular, you get:

• punctul
• important

But in the plural, you would get:

• punctele
• importante

So:

• Punctul este important. = singular
• Punctele sunt importante. = plural

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

So:

• este = is

This is the normal word used to link the subject and the adjective:

• Punctul este important.
• literally: The point is important.

It works just like English is in this sentence.

Yes. Very often, especially in everyday speech, Romanians use e instead of este.

So these both mean the same thing:

• Punctul este important.
• Punctul e important.

The version with este can sound a bit more formal or careful, while e is very common in normal conversation.

Because it is a cognate: Romanian important and English important come from the same Latin source.

Even though it looks familiar, it still follows Romanian grammar. It changes form to agree with the noun:

• masculine/neuter singular: important
• feminine singular: importantă
• masculine plural: importanți
• feminine/neuter plural: importante

In your sentence, punctul is singular and neuter, and neuter singular uses the masculine-looking form, so important is correct.

A simple English-friendly approximation is:

POONK-tool YEH-stee eem-por-TAHNT

A few notes:

• punctul ≈ POONK-tool
  • the ct is pronounced
• este ≈ YEH-ste
  • the initial e often sounds like ye
• important ≈ eem-por-TANT
  • stress is on the last syllable

This is only an approximation, but it is a good start.

No. Punct can mean several related things depending on context, such as:

• a point
• a dot
• a period / full stop
• a point in an argument or discussion
• a location / spot in some contexts

So Punctul este important could refer to:

• an important point in an argument
• an important item or issue
• a key point in general

The exact sense depends on context.

Yes. Punctul este important is the neutral, standard word order.

Structure:

• Punctul = subject
• este = verb
• important = predicate adjective

Romanian does allow word order changes for emphasis, but this version is the most straightforward and natural if you are simply stating a fact.

Normally, no. In a standard sentence like this, Romanian usually keeps the verb to be.

So the normal forms are:

• Punctul este important.
• Punctul e important.

Leaving it out entirely would usually sound incomplete or nonstandard in ordinary speech and writing.

Because this sentence is not using important directly before the noun. It is using important after the verb to be:

• The point is important

That is why the structure is:

• Punctul
  • este
    • important

If you wanted important to directly describe the noun inside a noun phrase, you would usually say:

• un punct important = an important point

So compare:

• Punctul este important. = The point is important.
• un punct important = an important point
