Στο γραφείο πίνω καφέ σε μια μεγάλη κούπα και βάζω το ποτήρι και τα μπισκότα σε έναν δίσκο.

Στο γραφείο means at the office or sometimes in the office.

• στο = a contraction of σε + το
• σε is a very common preposition that can mean in, at, to, on, depending on context
• το γραφείο = the office / the desk

So:

• σε το γραφείο → στο γραφείο

Greek often puts a place phrase early in the sentence for context, similar to English At the office, I drink coffee...

Also note that γραφείο can mean both office and desk, so context decides the best translation.

στο is the standard contracted form of σε το.

This happens very often in Greek:

• σε + το = στο
• σε + τη(ν) = στη(ν)
• σε + τα = στα
• σε + τον = στον

So στο γραφείο is not unusual or informal; it is the normal way to write it.

Greek usually leaves subject pronouns out when they are not needed, because the verb ending already shows the person.

Here:

• πίνω = I drink
• βάζω = I put

So Greek does not need εγώ unless you want emphasis:

• Εγώ πίνω καφέ = I drink coffee (maybe not someone else)

This is very common in Greek and is one of the first things English speakers notice.

All three are possible, but they mean slightly different things.

• πίνω καφέ = I drink coffee / I’m drinking coffee
  This is the most general or neutral version.
• πίνω έναν καφέ = I’m having a coffee
  This often suggests one coffee as a countable item.
• πίνω τον καφέ = I’m drinking the coffee
  This refers to a specific coffee already known in context.

So in your sentence, καφέ without an article sounds natural and general, much like English drink coffee.

Yes. καφές is the dictionary form, meaning coffee.

In the sentence, it appears as καφέ, which is the accusative singular form:

• nominative: ο καφές
• accusative: τον καφέ

After πίνω, the noun is the direct object, so Greek uses the accusative.

When the article is omitted, the noun still stays in the correct case:

• πίνω καφέ

That is a very common learner question. Greek σε covers a lot of meanings that English splits into different prepositions.

In this sentence:

• σε μια μεγάλη κούπα = in a large mug
• σε έναν δίσκο = on a tray

English chooses different prepositions based on the physical relationship. Greek often just uses σε and lets context do the rest.

So you should not expect a one-to-one match between Greek and English prepositions.

This means in a large mug.

Breakdown:

• σε = in / into
• μια = a / one
• μεγάλη = large, big
• κούπα = mug

The noun κούπα is feminine, so the article and adjective must agree with it.

That is why you get:

• μια for a feminine noun
• μεγάλη in the feminine singular form

Greek adjectives agree with the noun in:

• gender
• number
• case

Because the nouns have different genders.

• κούπα is feminine, so you use μια
• δίσκος is masculine, so you use έναν in the accusative

So:

• μια κούπα = a mug
• έναν δίσκο = a tray

This is part of Greek article and adjective agreement, which is much stronger than in English.

Because δίσκο is the direct object of the preposition σε, so it is in the accusative.

Compare:

• nominative: ένας δίσκος = a tray
• accusative: έναν δίσκο = a tray, as object

Greek changes both the article and often the noun ending when the case changes.

For masculine singular nouns like this:

• ο δίσκος
• τον δίσκο
• ένας δίσκος
• έναν δίσκο

Because nouns in Greek belong to grammatical genders, and those genders do not always match English logic.

Here:

• η κούπα = the mug, feminine
• το ποτήρι = the glass, neuter
• ο δίσκος = the tray, masculine

You usually have to learn each noun together with its article:

• η κούπα
• το ποτήρι
• ο δίσκος

That makes it much easier to form correct phrases later.

They are different kinds of drinking containers.

• κούπα = mug
• ποτήρι = glass

So the sentence says the speaker drinks coffee in a mug, and puts the glass and the biscuits/cookies on a tray.

A learner might wonder why both appear in the same sentence. It simply describes two different objects:

• the coffee is in the mug
• the glass and biscuits are placed on the tray

Because Greek often uses articles differently depending on whether the noun is general, indefinite, or specific.

In this sentence:

• καφέ is a general substance noun: coffee
• το ποτήρι = the glass
• τα μπισκότα = the biscuits/cookies

The last two sound like specific items, not just things in general.

So the sentence contrasts:

• a general activity: drink coffee
• specific objects: put the glass and the biscuits on a tray

Because τα μπισκότα means the biscuits or the cookies.

The singular is:

• το μπισκότο = the biscuit / cookie

The plural is:

• τα μπισκότα = the biscuits / cookies

This is a neuter noun, so:

• singular article: το
• plural article: τα

βάζω is a very common verb meaning put, place, set, and in some contexts even more than that.

Here it means:

• βάζω το ποτήρι και τα μπισκότα σε έναν δίσκο
• I put the glass and the biscuits on a tray

It is one of those broad everyday Greek verbs that appears in many expressions, so it is worth learning well.

Because the sentence connects two different things.

First και joins the two verbs:

• πίνω καφέ ... και βάζω ...
• I drink coffee ... and I put ...

Second και joins two objects:

• το ποτήρι και τα μπισκότα
• the glass and the biscuits

So each και has a different job:

• one links actions
• one links nouns

No, Greek word order is more flexible than English, although some orders sound more natural than others.

This sentence:

• Στο γραφείο πίνω καφέ σε μια μεγάλη κούπα και βάζω το ποτήρι και τα μπισκότα σε έναν δίσκο.

puts the location first: At the office...

That is natural because it sets the scene first. Greek often moves parts of the sentence around for emphasis, topic, or style.

For example, other orders may still be grammatical, but they may sound different in focus.

Yes. γραφείο can mean:

• office
• desk

So στο γραφείο could mean:

• at the office
• at the desk
• in the office

Context tells you which meaning is intended. If the learner has already been given the translation, then that translation is the one to follow here, but it is useful to know that the Greek word itself can be ambiguous.

In Modern Greek, σε is followed by the accusative.

That is why you see:

• στο γραφείο
• σε μια μεγάλη κούπα
• σε έναν δίσκο

Even though English may say in, at, to, or on, Greek still uses σε + accusative in many such cases.

That is an important pattern to learn early:

• σε
  • accusative noun phrase
