Στο τέλος της μέρας γυαλίζω τα γυαλιά μου και μετά ξεπλένω το πρόσωπό μου με κρύο νερό.

Στο is the normal contraction of σε + το.

• σε = in / at / to
• το = the for a neuter singular noun

So στο τέλος literally means at the end.

This contraction is extremely common in Greek:

• σε το → στο
• σε τη(ν) → στη(ν)

της μέρας is in the genitive case, and it means of the day.

So the phrase breaks down like this:

• στο τέλος = at the end
• της μέρας = of the day

Altogether: at the end of the day.

After nouns like τέλος (end), Greek often uses the genitive to show what something belongs to or is the end of.

μέρα is the common everyday form of ημέρα (day).

So:

• η μέρα = everyday spoken Greek
• η ημέρα = more formal / more careful style

Their genitives are:

• της μέρας
• της ημέρας

Both are correct, but της μέρας sounds more natural in ordinary speech.

It can be both, depending on context.

• Literal: At the end of the day / in the evening
• Idiomatic: When all is said and done / ultimately

In this sentence, it is most naturally literal, because it introduces a routine action: polishing glasses and rinsing the face.

No. τα γυαλιά usually means glasses / eyeglasses as a normal plural noun, even when you mean one pair.

This is similar to English, where we also say glasses rather than a glass for eyewear.

Important distinction:

• το γυαλί = glass, pane, or lens/material
• τα γυαλιά = glasses / spectacles

So γυαλίζω τα γυαλιά μου means I polish/clean my glasses.

Yes, they are related in origin.

They come from the same basic idea of shine / glass / glossy surface:

• γυαλί = glass
• γυαλιά = glasses
• γυαλίζω = to polish / to make shiny / to shine

In this sentence, γυαλίζω τα γυαλιά μου means something like I polish / clean my glasses so they shine.

Because Greek usually places these weak possessive pronouns after the noun.

So:

• τα γυαλιά μου = my glasses
• το πρόσωπό μου = my face

This is the normal Greek pattern. English uses my + noun, but Greek commonly uses:

article + noun + possessive pronoun

For example:

• το σπίτι μου = my house
• η φίλη μου = my friend

Greek usually keeps the article even when a possessive is present.

So Greek prefers:

• το πρόσωπό μου
• τα γυαλιά μου

rather than dropping the article.

This is very normal Greek structure. English says my face, but Greek more literally says the face my.

This happens because μου is an enclitic word, and Greek spelling sometimes adds an extra accent to preserve the correct stress pattern.

The base noun is:

• πρόσωπο

When followed by enclitic μου, it becomes:

• πρόσωπό μου

This extra accent does not mean the word changes meaning. It is a spelling/stress rule.

You will see the same thing in other phrases too, especially when the main word is stressed on the third syllable from the end.

Both are in the present tense.

• γυαλίζω = I polish / I am polishing
• ξεπλένω = I rinse / I am rinsing

In Greek, the present tense can describe:

• a habit or routine
• something happening right now
• a general repeated action

In this sentence, with Στο τέλος της μέρας, the most natural reading is a routine/habitual one: this is what the speaker does at the end of the day.

πλένω means I wash.

ξεπλένω means I rinse or rinse off.

The prefix ξε- often adds the idea of:

• removing something
• washing/rinsing away
• undoing or clearing off

So here:

• πλένω το πρόσωπό μου = I wash my face
• ξεπλένω το πρόσωπό μου = I rinse my face

Because με κρύο νερό means with cold water in a general, nonspecific way.

Greek often omits the article with materials or means when speaking generally:

• με νερό = with water
• με σαπούνι = with soap
• με κρύο νερό = with cold water

If you say με το κρύο νερό, that usually points to specific cold water already known in the context, something like with the cold water.

There are two main cases here:

1. Accusative for direct objects

• τα γυαλιά μου
• το πρόσωπό μου

These are the things the speaker polishes and rinses.

2. Genitive in της μέρας

• this depends on τέλος
• it means of the day

So:

• γυαλίζω τα γυαλιά μου → object in accusative
• ξεπλένω το πρόσωπό μου → object in accusative
• στο τέλος της μέρας → genitive after τέλος

Because they are neuter nouns, and in Greek many neuter nouns have the same form in the nominative and accusative.

Examples here:

• τα γυαλιά = same form in nominative and accusative
• το πρόσωπο = same form in nominative and accusative

So the role is understood from the verb and sentence structure, not from a visible change in the noun ending.

Here μετά means then / afterwards.

So:

• και μετά = and then

Its position is fairly natural here, between the two actions:

• first: γυαλίζω τα γυαλιά μου
• then: ξεπλένω το πρόσωπό μου

Greek word order is flexible, so you may also see μετά in slightly different positions, but here it is in a very standard place.

The sentence’s word order is natural, but Greek does allow flexibility.

This version is neutral and clear:

• Στο τέλος της μέρας γυαλίζω τα γυαλιά μου και μετά ξεπλένω το πρόσωπό μου με κρύο νερό.

Greek can move things around for emphasis, contrast, or style. For example, a speaker might shift μετά or place an object earlier for emphasis. But the given order is the most straightforward everyday wording for a learner to copy.
