Η διαταγή είναι εδώ.

Η is the feminine singular definite article, so it means the.

In this sentence, it goes with διαταγή, because διαταγή is a feminine singular noun. It is capitalized only because it is the first word of the sentence; normally you would see η.

It is pronounced ee.

You can tell mainly from the article: η διαταγή.

In Greek, the article usually shows the gender clearly:

• ο = masculine
• η = feminine
• το = neuter

So when you see η διαταγή, you know the noun is feminine. The ending -ή is also very common for feminine nouns, though the article is the most reliable clue.

Yes. In Greek, the article must match the noun in:

• gender
• number
• case

Here, both words are:

• feminine
• singular
• nominative

So η διαταγή is a matching pair. This kind of agreement is very important in Greek grammar.

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

The basic structure is:

• η διαταγή = the subject
• είναι = is
• εδώ = here

So Greek keeps η διαταγή in the nominative, just as English uses the order as the subject in The order is here.

Είναι is the present-tense form of είμαι, which means to be.

Here it means is.

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

• he/she/it is
• they are

So Greek learners often need to rely on the subject to tell whether it is singular or plural.

Because Greek verbs do not change for grammatical gender.

The noun διαταγή is feminine, but the verb stays είναι because verbs agree with the subject in person and number, not in gender.

So:

• a masculine subject can use είναι
• a feminine subject can use είναι
• a neuter subject can use είναι

Gender affects things like articles and adjectives much more than verbs.

Yes. Greek word order is more flexible than English word order.

This sentence:

• Η διαταγή είναι εδώ.

could also appear as:

• Εδώ είναι η διαταγή.

Both are grammatical, but the emphasis changes a little:

• Η διαταγή είναι εδώ is a neutral way to say it.
• Εδώ είναι η διαταγή puts more emphasis on here.

So Greek word order often helps show focus, not just grammar.

The accent mark shows which syllable is stressed.

So:

• διαταγή → stress on the last syllable
• είναι → stress on the first syllable
• εδώ → stress on the second syllable

The article η has no accent because it is only one syllable. In Modern Greek spelling, monosyllabic words usually do not take an accent mark.

A rough English-style guide is:

ee thee-ah-ta-YEE EE-ne eh-THOH

A few pronunciation notes:

• δ sounds like the th in this, not the th in think
• ει is pronounced like ee
• γ before η/ι has a soft sound, a bit like an English y, but stronger

So a slightly more careful approximation would be:

• Η = ee
• διαταγή = thee-ah-ta-YEE
• είναι = EE-ne
• εδώ = eh-THOH

Not exactly. Διαταγή usually means order in the sense of:

• a command
• an instruction
• an official order

It often sounds formal, official, or authoritative.

It is not the usual word for a restaurant or shopping order. For that, Greek normally uses παραγγελία.

So if a learner sees διαταγή, it is helpful to think of command / directive / official order, depending on context.
