Η ευζωία είναι σημαντική.

A good approximate pronunciation is:

• Η → ee
• ευζωία → ev-zo-EE-a
• είναι → EE-ne
• σημαντική → see-man-dee-KEE

So the whole sentence is roughly:

ee ev-zo-EE-a EE-ne see-man-dee-KEE

A useful detail: ευ can sound like ev or ef. Here it is ev because the next sound, ζ, is voiced.

Because η is the feminine singular definite article, meaning the.

Greek often uses the definite article with abstract nouns much more naturally than English does. So where English might say just well-being is important, Greek commonly says the well-being is important in form, even though the natural English translation usually drops the.

Here η also tells you that ευζωία is:

• feminine
• singular
• nominative

ευζωία is:

• feminine
• singular
• nominative

It is nominative because it is the subject of the sentence: Η ευζωία είναι σημαντική = Well-being is important.

The ending -ία is very often found in feminine nouns, so that is a helpful pattern to notice.

Because adjectives in Greek agree with the noun they describe in:

• gender
• number
• case

Since ευζωία is feminine singular nominative, the adjective must also be feminine singular nominative:

• masculine: σημαντικός
• feminine: σημαντική
• neuter: σημαντικό

So σημαντική is the correct form to match η ευζωία.

είναι is the present-tense form of είμαι, meaning to be.

In this sentence it means is.

A useful thing to know: in Modern Greek, είναι is used for both:

• he/she/it is
• they are

So Greek does not change this form based on gender, and this particular form is also the same in singular and plural third person.

The neutral, straightforward order is:

Η ευζωία είναι σημαντική.

Greek word order is more flexible than English, so you can move things for emphasis. For example:

• Σημαντική είναι η ευζωία.

This still means essentially the same thing, but it emphasizes σημαντική.

However, changing the structure can also change the meaning. For example:

• η σημαντική ευζωία

does not mean the same thing as the full sentence. That means the important well-being, which is a noun phrase, not a complete sentence.

The accent mark shows which syllable is stressed.

In this sentence:

• ευζωία → stress on -ί-
• είναι → stress on the first syllable
• σημαντική → stress on the last syllable

Stress matters in Greek pronunciation, so the written accent is important and should be learned as part of the word.

Normally, no.

In standard everyday Greek, you would usually keep both:

• η because the noun naturally takes the article here
• είναι because it is the verb is

So the normal full sentence is:

Η ευζωία είναι σημαντική.

You might see omissions in headlines, notes, or poetic language, but that is not the standard form a learner should start with.

It is a real and useful word, but it can sound a bit formal or abstract depending on context.

You will often meet it in set phrases and more formal discussion, especially in contexts like welfare or quality of life, for example:

• η ευζωία των ζώων = animal welfare

So it is definitely worth learning, but depending on context, everyday Greek might sometimes use other expressions too.
