Η λογιστική ημερομηνία είναι σωστή.

Word by word:

• Η = the (feminine singular)
• λογιστική = accounting / bookkeeping (here it works as an adjective: accounting)
• ημερομηνία = date
• είναι = is
• σωστή = correct / right

So the structure is literally:

The accounting date is correct.

Η is the definite article, meaning the.

It is used because ημερομηνία is a feminine singular noun, and the phrase refers to a specific date: the accounting date.

Greek articles change for gender, number, and case, so Η is specifically the form used here for a feminine singular noun in the nominative case.

Yes. In this sentence, λογιστική describes ημερομηνία, so it functions as an adjective meaning accounting.

Base idea:

• λογιστική can also be a noun in other contexts, meaning accounting as a field.
• But here, because it comes directly before ημερομηνία, it means accounting date.

So:

• λογιστική ημερομηνία = accounting date

Because Greek adjectives often come before the noun they describe, just like in English.

So:

• λογιστική ημερομηνία = accounting date

That said, Greek word order is often more flexible than English, but this is the normal, straightforward order.

Because they both agree with ημερομηνία, which is:

• feminine
• singular
• nominative

In Greek, adjectives must agree with the noun they describe or refer to.

So:

• ημερομηνία = feminine singular
• λογιστική = feminine singular
• σωστή = feminine singular

This is a very important Greek pattern: adjectives change their form to match the noun.

Because σωστή is a predicate adjective after είναι.

In English, we say:

• The date is correct

not

• The date is the correct

Greek works the same way here:

• Η ημερομηνία είναι σωστή = The date is correct

If you added an article before σωστή, it would change the structure and meaning.

είναι is the 3rd person singular present tense of είμαι, which means to be.

So it means:

• is

Examples:

• Η ημερομηνία είναι σωστή. = The date is correct.
• Το βιβλίο είναι καλό. = The book is good.

A useful mini-pattern is:

• είμαι = I am
• είσαι = you are
• είναι = he/she/it is

It is in the nominative case, because it is the subject of the sentence.

The subject is the thing that is something:

• Η λογιστική ημερομηνία = the accounting date
• είναι σωστή = is correct

So the date is the subject, and that is why the noun phrase appears in the nominative.

Yes, Greek word order is more flexible than English.

The neutral, standard version is:

• Η λογιστική ημερομηνία είναι σωστή.

But Greek can move things around for emphasis, for example:

• Σωστή είναι η λογιστική ημερομηνία.

This would sound more marked, with extra focus on σωστή.

For learners, the safest pattern is: subject + είναι + adjective

A simple pronunciation guide is:

ee lo-yi-stee-KEE ee-me-ro-mee-NEE-a EE-ne so-STEE

A few helpful notes:

• Η is pronounced ee
• γ before ι sounds somewhat like a soft y
• εί in είναι sounds like ee
• The stressed syllables are:
  • λογιστική
  • ημερομηνία
  • σωστή

So the rhythm is important: Η λογιστική ημερομηνία είναι σωστή.

It can mean either, depending on context.

In this sentence, σωστή most naturally means:

• correct
• accurate
• right

So Η λογιστική ημερομηνία είναι σωστή means the date is correct, not mistaken.

You would change the article, adjective, noun, and final adjective to plural forms:

• Οι λογιστικές ημερομηνίες είναι σωστές.

That means:

• The accounting dates are correct.

Notice the agreement:

• Οι = the (plural)
• λογιστικές = accounting (feminine plural)
• ημερομηνίες = dates
• σωστές = correct (feminine plural)

This is a good example of how Greek agreement works across the whole sentence.
