Asigurarea este importantă.

Because Romanian usually puts the definite article at the end of the noun.

• asigurare = insurance / an insurance policy / insurance in general (depending on context)
• asigurarea = the insurance

So the -a here is the feminine singular definite article attached to the noun.

This is one of the big differences from English:

• English: the insurance
• Romanian: asigurarea

Asigurarea is a feminine singular noun here, and the adjective has to agree with it.

That is why you get:

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

So in Asigurarea este importantă, the adjective is feminine singular because it describes asigurarea.

In standard Romanian, you normally do not omit the verb to be in this kind of sentence.

So:

• Asigurarea este importantă. = correct, standard
• Asigurarea importantă. = not standard Romanian

You may also hear the shorter spoken form:

• Asigurarea e importantă.

That is very common in everyday speech, but este is the full form.

Yes, Romanian word order is fairly flexible, but the neutral, most natural version is:

• Asigurarea este importantă.

You can also say:

• Importantă este asigurarea.

That version is more marked or emphatic, something like What is important is the insurance or The insurance is what’s important.

So for a learner, the basic pattern to remember is:

• noun + este + adjective

The letter ă is a very common Romanian vowel. It is a short, neutral sound, similar to the a in English sofa for many speakers, though not exactly the same.

So:

• importantă ends with -tă
• that final ă is not a strong ah sound

A rough learner-friendly pronunciation is:

• im-por-TAN-tuh

But remember that ă is its own Romanian sound, not just an unstressed English a.

A simple learner-friendly breakdown is:

• a-si-gu-RA-re-a

The stress falls on RA:

• a-si-gu-RA-re-a

The ending -rea is pronounced clearly; Romanian spelling is usually quite phonetic, so you should pronounce the written vowels rather than reducing them heavily like in English.

It can mean either, depending on context.

Romanian asigurare / asigurarea can refer to:

• insurance as a general concept
• an insurance policy
• a specific insurance arrangement, such as health, car, or travel insurance

So Asigurarea este importantă could mean:

• Insurance is important
• The insurance is important
• The insurance policy is important

The context usually tells you which one is meant.

Romanian often uses the definite form in places where English may use a bare noun.

So even if English says:

• Insurance is important

Romanian may naturally say:

• Asigurarea este importantă

This can sound more natural in Romanian when talking about the concept in a general, familiar, or contextually understood way. In other situations, Romanian can also use the indefinite form:

• Asigurarea este importantă = The insurance / Insurance is important
• O asigurare este importantă = An insurance policy is important
• Asigurare este importantă would generally not be the normal choice here

Not always, but very often.

In this sentence, the adjective comes after the verb because it is part of the predicate:

• Asigurarea este importantă.

When an adjective directly modifies a noun, it is also usually placed after the noun:

• asigurare importantă = important insurance

However, some adjectives can come before the noun for style, emphasis, or because they are more subjective. But for a beginner, the safest rule is:

• Romanian adjectives usually come after the noun
• predicate adjectives come after este

The dictionary forms are:

• asigurare = noun, insurance
• a fi = verb, to be
• important = adjective, important

In the sentence:

• asigurarea = definite form of asigurare
• este = 3rd person singular of a fi
• importantă = feminine singular form of important

So a Romanian learner should try to recognize both the base form and the changed form used in the sentence.

Yes.

These are both correct:

• Asigurarea este importantă.
• Asigurarea e importantă.

The difference is mainly style:

• este = fuller, slightly more formal or careful
• e = very common in everyday speech

For learners, it is good to know both, but este is often introduced first because it is clearer and more complete.
