Έχεις δίκιο, αυτό το λεωφορείο αργεί πάντα το απόγευμα.

Because έχω δίκιο is the normal Greek idiom for to be right.

• έχεις = you have
• δίκιο = right, justification, or reason

So Greek expresses this idea as you have right, not you are right.

A less natural learner-style translation like είσαι σωστός would usually mean you are correct in a more literal sense, but it is not the everyday idiom used here.

έχεις is:

• the present tense
• 2nd person singular
• from the verb έχω = to have

So it means you have when speaking to one person informally.

Related forms:

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

If you were speaking formally or to more than one person, you would say έχετε δίκιο.

Greek often leaves out subject pronouns because the verb ending already shows who the subject is.

So:

• έχεις already means you have
• you do not need εσύ unless you want emphasis or contrast

For example:

• Έχεις δίκιο. = You’re right.
• Εσύ έχεις δίκιο, όχι εγώ. = You’re right, not me.

This is very different from English, where the subject usually has to be stated.

In Modern Greek, demonstratives normally go together with the definite article.

So the pattern is:

• αυτό το λεωφορείο = this bus
• literally: this the bus

This is standard Greek structure:

• αυτό το σπίτι = this house
• αυτή η πόρτα = this door
• αυτό το παιδί = this child

English does not use the after this, but Greek usually does.

They all match in gender, number, and case.

Here they are all:

• neuter
• singular
• functioning as the subject of the sentence

Breakdown:

• αυτό = this
• το = the
• λεωφορείο = bus

λεωφορείο is a neuter noun, so the demonstrative and article must also be neuter:

• αυτό το λεωφορείο

In this sentence, αυτό το λεωφορείο means this bus.

In Modern Greek, αυτός / αυτή / αυτό often covers what English divides into this and sometimes that, depending on context. But in beginner learning, it is safest to understand:

• αυτό το... = this...
• εκείνο το... = that...

So here:

• αυτό το λεωφορείο = this bus
• εκείνο το λεωφορείο = that bus

Yes, and this is an important distinction.

• αργός = slow (an adjective)
• αργεί = is late / is delayed (a verb form from αργώ)

So:

• Το λεωφορείο είναι αργό. = The bus is slow.
• Το λεωφορείο αργεί. = The bus is late.

In your sentence, the meaning is about schedule or arrival time, so Greek uses the verb αργεί, not the adjective αργό.

αργεί is:

• present tense
• 3rd person singular
• from the verb αργώ

Here it means:

• it is late
• it is delayed
• literally, referring to the bus

Because το λεωφορείο is singular, the verb is singular too:

• το λεωφορείο αργεί = the bus is late

πάντα means always, and Greek adverbs are fairly flexible in position.

Here:

• αργεί πάντα το απόγευμα = is always late in the afternoon

This placement is very natural. πάντα is modifying the whole idea of the bus being late.

You could also hear slightly different word orders, depending on emphasis, for example:

• πάντα αργεί το απόγευμα
• το απόγευμα αργεί πάντα

But the version in your sentence is straightforward and idiomatic.

Yes, it does mean in the afternoon, but Greek often uses a time expression without a preposition.

So:

• το απόγευμα = in the afternoon
• literally: the afternoon

This is common in Greek with expressions of time:

• το πρωί = in the morning
• το βράδυ = in the evening / at night
• τη Δευτέρα = on Monday
• τον χειμώνα = in winter

So the lack of a preposition is normal Greek grammar.

Greek often uses the singular time expression for a repeated time frame.

So:

• πάντα το απόγευμα = always in the afternoon

This refers to a regular pattern, not just one specific afternoon.

You may also hear plural forms in other contexts, such as:

• τα απογεύματα = in the afternoons

Both can express habitual meaning, but το απόγευμα is very common and natural here.

A rough pronunciation guide is:

EH-his DHEE-kyo, af-TO to le-o-fo-REE-o ar-GHEE PAN-da to a-PO-ghev-ma

Main stressed syllables:

• Έχεις
• δίκιο
• αυτό
• λεωφορείο
• αργεί
• πάντα
• απόγευμα

A few useful notes:

• χ in έχεις is not like English ch; it is a Greek throaty sound.
• δ in Modern Greek sounds like the th in this, not like English d.
• γ before ε in απόγευμα is a softer sound.

The accent marks in Greek show you which syllable is stressed, and they are important for correct pronunciation.

Very roughly, it breaks down like this:

• Έχεις δίκιο = You have right → You’re right
• αυτό το λεωφορείο = this the bus → this bus
• αργεί = is late
• πάντα = always
• το απόγευμα = in the afternoon

So the full structure is something like:

You’re right, this bus is always late in the afternoon.

This is a good example of how Greek often uses:

• an idiom instead of a literal English structure
• article + demonstrative together
• a bare time expression without a preposition
