Η δασκάλα μιλάει με ήρεμη φωνή.

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

In this sentence, it goes with δασκάλα because δασκάλα is a feminine singular noun:

• η δασκάλα = the teacher (female)

Because it is at the beginning of the sentence, it is capitalized: Η instead of η.

Greek nouns change form for grammatical gender.

• δάσκαλος = male teacher
• δασκάλα = female teacher

So Η δασκάλα specifically means the female teacher. The article also changes to match:

• ο δάσκαλος = the male teacher
• η δασκάλα = the female teacher

δασκάλα is the subject of the sentence, the person doing the action.

The action is μιλάει = speaks / is speaking, so the sentence structure is:

• Η δασκάλα = the teacher
• μιλάει = speaks
• με ήρεμη φωνή = with a calm voice

Because it is the subject, δασκάλα is in the nominative case.

μιλάει is the verb speaks / is speaking.

It is:

• present tense
• third person singular

So it means:

• she speaks
• she is speaking

Greek present tense can often cover both the simple present and the progressive idea, depending on context.

Yes. Both μιλάει and μιλά are common and correct in Modern Greek.

So these are both natural:

• Η δασκάλα μιλάει με ήρεμη φωνή.
• Η δασκάλα μιλά με ήρεμη φωνή.

They mean the same thing. A learner will see both forms, so it is good to recognize them as equivalents.

με usually means with.

Here it introduces the way or manner in which the teacher speaks:

• με ήρεμη φωνή = with a calm voice

In natural English, this is often translated as:

• in a calm voice
• with a calm voice

So με does not always mean literal physical accompaniment; it can also describe manner.

Because ήρεμη is an adjective and it has to agree with φωνή.

The noun φωνή is:

• feminine
• singular

So the adjective must also be feminine singular:

• ήρεμος = calm (masculine)
• ήρεμη = calm (feminine)
• ήρεμο = calm (neuter)

Since φωνή is feminine, Greek uses ήρεμη φωνή = calm voice.

After με, Greek normally uses the accusative case.

So φωνή here is accusative. However, for many feminine nouns in -η, the nominative singular and accusative singular look the same.

That means:

• nominative: φωνή
• accusative: φωνή

So the case has changed grammatically, but the form has not changed visibly.

The same thing happens with ήρεμη here: it matches φωνή, and in this form the feminine nominative and accusative singular are identical.

Because με ήρεμη φωνή is being used as a descriptive phrase of manner, not as a separate, specific object.

Greek often says:

• με ήρεμη φωνή = with a calm voice
• με χαμηλή φωνή = with a low voice
• με δυνατή φωνή = with a loud voice

This is a very natural pattern. Adding an article would change the feel and usually would not be the normal choice in this sentence.

No, Greek word order is more flexible than English word order.

Η δασκάλα μιλάει με ήρεμη φωνή is a neutral, natural order:

• subject + verb + phrase of manner

But Greek can move things around for emphasis. For example, a different order could be used in a different context. Even so, the given sentence is the most straightforward way to say it.

So for a learner, this version is a good basic model.

Yes. Greek could also express a similar idea with an adverb:

• Η δασκάλα μιλάει ήρεμα. = The teacher speaks calmly.

The difference is small but useful:

• με ήρεμη φωνή focuses on the voice
• ήρεμα focuses more generally on the manner

Both are natural, but they are not exactly identical in emphasis.

A simple pronunciation guide is:

i dha-SKA-la mi-LA-i me I-re-mi fo-NI

A few helpful sound notes:

• δ sounds like the th in this
• η and ι both sound like ee
• αι in μιλάει sounds like e / ee in modern pronunciation, depending on how you describe it for learners
• the stress is shown by the accent marks:
  • δασκάλα
  • μιλάει
  • ήρεμη
  • φωνή

So the natural pronunciation is approximately: i ða-SKA-la mi-LA-i me I-re-mi fo-NI
