Η κόρη της έχει καστανά μάτια και χαμογελαστό πρόσωπο.

Η is the feminine singular definite article, meaning the.

Here it goes with κόρη (daughter), which is a feminine singular noun:

• η κόρη = the daughter

It appears as Η with a capital letter simply because it is the first word of the sentence.

Here της means her.

In Greek, possession is often expressed with the genitive form after the noun:

• η κόρη της = her daughter
  literally: the daughter of her

So της here is not the; it is a possessive/genitive form meaning her.

Greek usually expresses this kind of possession as:

• article + noun + genitive pronoun

So:

• η κόρη της = her daughter
• το σπίτι μου = my house
• ο φίλος του = his friend

This is the normal Greek structure. English puts the possessor first (her daughter), but Greek often puts it after the noun.

Έχει is the 3rd person singular present tense of έχω, which means to have.

So:

• έχω = I have
• έχεις = you have
• έχει = he/she/it has

In this sentence:

• Η κόρη της έχει... = Her daughter has...

Because adjectives in Greek must agree with the noun in gender, number, and case.

μάτια (eyes) is:

• neuter
• plural

So the adjective must also be neuter plural:

• καστανά μάτια = brown eyes

Compare:

• καστανός = masculine singular
• καστανή = feminine singular
• καστανό = neuter singular
• καστανά = neuter plural

Because μάτια means eyes, and Greek uses the plural here just like English does.

Singular:

• το μάτι = the eye

Plural:

• τα μάτια = the eyes

So:

• καστανά μάτια = brown eyes

Καστανά means brown, but more specifically it often has the sense of chestnut-brown.

In Greek, καστανός / καστανή / καστανό is very commonly used for:

• hair
• eyes
• sometimes skin tone or other natural coloring

So καστανά μάτια is a very natural way to say brown eyes.

Literally, it means something like:

• smiling face
• smiley face
• pleasant, smiling expression

The adjective χαμογελαστό comes from the idea of smiling:

• χαμογελώ = to smile
• χαμογελαστός / -ή / -ό = smiling, cheerful-looking

So χαμογελαστό πρόσωπο describes a face that looks friendly or smiling.

Because πρόσωπο is a neuter singular noun.

That means the adjective must also be neuter singular:

• χαμογελαστό πρόσωπο = correct

Compare the forms:

• χαμογελαστός = masculine singular
• χαμογελαστή = feminine singular
• χαμογελαστό = neuter singular

Since το πρόσωπο is neuter, χαμογελαστό is the correct form.

In Greek, when describing what someone has, the objects often appear without the article, especially in simple descriptions of physical features.

So:

• έχει καστανά μάτια = she has brown eyes
• έχει χαμογελαστό πρόσωπο = she has a smiling face

This is very natural Greek. Adding articles could change the tone or make it sound more specific.

Because both noun phrases are linked by και (and) and share the same verb.

So Greek says:

• έχει καστανά μάτια και χαμογελαστό πρόσωπο

This works just like English:

• She has brown eyes and a smiling face

You do not need to repeat the verb unless you want extra emphasis.

Και means and.

It connects the two things that the daughter has:

• καστανά μάτια
• χαμογελαστό πρόσωπο

So the structure is:

• has [brown eyes] and [a smiling face]

Πρόσωπο most often means face, but it can also mean:

• person
• figure
• character
  depending on context

In this sentence, because it is describing physical appearance, πρόσωπο clearly means face.

Yes. A very literal translation would be:

• Her daughter has brown eyes and a smiling face.

A more natural English version might be:

• Her daughter has brown eyes and a cheerful face.
• Her daughter has brown eyes and a warm smile.
  depending on the context

The Greek phrase χαμογελαστό πρόσωπο suggests a face with a smiling or cheerful expression, not necessarily that she is smiling at this exact moment.

The sentence breaks down like this:

• Η κόρη της = her daughter
• έχει = has
• καστανά μάτια = brown eyes
• και = and
• χαμογελαστό πρόσωπο = a smiling face

So the pattern is:

• subject + verb + object + and + object

This is a very common and straightforward Greek sentence pattern.
