Ο παλαιοπώλης περιμένει στο παλαιοπωλείο.

Ο is the masculine singular definite article in Greek, so here it means the.

• ο = the (masculine)
• η = the (feminine)
• το = the (neuter)

So Ο παλαιοπώλης means the antique dealer / junk dealer / second-hand dealer, depending on context.

Greek often uses the definite article more regularly than English, especially with nouns that refer to a specific person or thing.

So ο παλαιοπώλης is the normal way to say the antique dealer.
If you said just παλαιοπώλης, it would sound more like an antique dealer or like a dictionary/headword form, depending on context.

παλαιοπώλης is a noun meaning someone who sells old things, usually:

• antique dealer
• second-hand dealer
• sometimes junk dealer

It is made from parts meaning roughly:

• παλαιο- = old
• -πώλης = seller, dealer

So the word literally suggests seller of old things.

They are closely related, but one is a person and the other is a place:

• παλαιοπώλης = the dealer, the seller
• παλαιοπωλείο = the shop, the antique shop / second-hand shop

This is a very common Greek pattern:

• person: -πώλης
• shop/place: -πωλείο

So:

• Ο παλαιοπώλης = the dealer
• στο παλαιοπωλείο = in/at the shop

The ending -ης is a very common ending for masculine nouns in Greek.

Here, παλαιοπώλης is masculine, and in this sentence it is in the nominative singular, because it is the subject of the verb.

You do not need to memorize every detail at once, but it helps to notice that many masculine nouns look like this:

• ο μαθητής = the student
• ο πωλητής = the salesman
• ο παλαιοπώλης = the antique dealer

περιμένει means waits or is waiting.

Greek present tense can often translate into English in more than one way:

• he waits
• he is waiting

Which one sounds better in English depends on context.

So the sentence could be understood as:

• The antique dealer waits in the shop
• The antique dealer is waiting in the shop

Greek often omits subject pronouns when they are not needed, because the verb ending already shows the person and number.

Here, περιμένει can mean:

• he waits / is waiting
• she waits / is waiting
• it waits / is waiting

But because the noun ο παλαιοπώλης is already there, Greek does not need a separate word for he.

This is very normal in Greek.

περιμένει is the third person singular present tense of περιμένω (to wait).

So it is used with:

• he
• she
• it

A few present-tense forms are:

• περιμένω = I wait / am waiting
• περιμένεις = you wait / are waiting
• περιμένει = he/she/it waits / is waiting

στο means in the, at the, or sometimes to the, depending on context.

It is a contraction of:

• σε = in, at, to
• το = the

So:

• σε το → στο

This contraction is standard in modern Greek.

Examples:

• στο σπίτι = in the house / at home
• στο σχολείο = at school / to the school
• στο παλαιοπωλείο = in/at the antique shop

Because the correct word is παλαιοπωλείο, with the stress on -λεί-? Actually, the stress is on the final -είο pattern: πα-λαι-ο-πω-λεί-ο? Let’s state it clearly:

The correct spelling is παλαιοπωλείο.

This is the normal noun ending -είο, which is common for places or establishments, such as:

• βιβλιοπωλείο = bookstore
• ζαχαροπλαστείο = pastry shop
• κουρείο = barber shop
• παλαιοπωλείο = antique shop

So you should learn παλαιοπωλείο as the full dictionary form.

After σε (and therefore after στο), Greek normally uses the accusative.

So in grammar terms:

• το παλαιοπωλείο = nominative / accusative singular
• στο παλαιοπωλείο = literally in/at/to the shop, with σε + accusative

In this particular noun, the nominative and accusative forms look the same, because it is a neuter noun. That is very common in Greek.

Here it means in or at.

So Ο παλαιοπώλης περιμένει στο παλαιοπωλείο means the dealer is waiting in/at the antique shop.

Greek σε / στο covers several meanings that English often separates:

• in
• at
• to

The exact English translation depends on context.

A simple learner-friendly pronunciation guide would be:

• παλαιοπώλης ≈ pa-le-o-PO-lis
• παλαιοπωλείο ≈ pa-le-o-po-LEE-o

A few useful notes:

• αι sounds like e in modern Greek
• ω and ο are both pronounced like o
• the written accent mark shows which syllable is stressed

So the stress is on:

• παλαιοπώλης → -πώ-
• παλαιοπωλείο → -εί-

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

The neutral order here is:

• Ο παλαιοπώλης περιμένει στο παλαιοπωλείο.

But Greek could also move things around for emphasis, for example:

• Στο παλαιοπωλείο περιμένει ο παλαιοπώλης.
• Περιμένει στο παλαιοπωλείο ο παλαιοπώλης.

These still mean basically the same thing, but the emphasis changes slightly.

English is usually less flexible, so learners should not expect Greek word order to map perfectly onto English word order.

It could be either, depending on context.

Greek present tense can express:

• a habit: The antique dealer waits in the shop
• something happening right now: The antique dealer is waiting in the shop

Without extra context, both are possible.

The accent marks show which syllable is stressed when the word is pronounced.

For example:

• παλαιοπώλης → stress on πώ
• περιμένει → stress on μέ
• παλαιοπωλείο → stress on εί

In Greek, accent marks are important because they are part of normal spelling and help you pronounce words correctly.

Yes. The article το tells you that παλαιοπωλείο is neuter singular.

So:

• ο παλαιοπώλης = masculine singular
• το παλαιοπωλείο = neuter singular

This is useful because Greek articles give you grammatical information that English articles do not.

Not perfectly.

A very literal breakdown is:

• Ο = the
• παλαιοπώλης = antique dealer / second-hand dealer
• περιμένει = waits / is waiting
• στο = in/at the
• παλαιοπωλείο = antique shop / second-hand shop

But good English translation depends on context. A natural translation would usually be:

• The antique dealer is waiting in the antique shop.
• or The antique dealer waits in the antique shop.

So word-for-word translation can help you understand structure, but it does not always produce natural English.
