Σε αυτό το σημείο περιμένω κάθε μέρα το λεωφορείο.

This phrase means at this spot / at this point and gives the location first.

Greek often puts location or time information near the beginning of a sentence, especially when it sets the scene. So this order is very natural.

You could also say:

Περιμένω το λεωφορείο σε αυτό το σημείο κάθε μέρα.

That is also correct, but the emphasis feels a little different.

στο σημείο means at the spot / at the point.

σε αυτό το σημείο means at this spot / at this point.

So the difference is that αυτό adds the idea of this.

Also, στο is the contraction of σε + το, but here the noun phrase is αυτό το σημείο, so Greek keeps σε separate:

• σε αυτό το σημείο
• often written σ’ αυτό το σημείο before a vowel

Because σε takes the accusative case, and σημείο is a neuter noun.

For many neuter nouns in Greek, the nominative and accusative singular look the same. So even though the case has changed, the form does not change visibly.

Here:

• nominative: το σημείο
• accusative: το σημείο

So after σε, the noun is accusative, but it still looks the same.

Because αυτό has to agree with σημείο in gender, number, and case.

σημείο is:

• neuter
• singular

So the correct demonstrative is αυτό.

Compare:

• αυτό το σημείο = this point/spot
• αυτή η μέρα = this day
• αυτός ο δρόμος = this road

Περιμένω is the present tense, first person singular: I wait / I am waiting.

In Greek, the present tense can describe:

• something happening right now
• something that happens regularly

Here, because of κάθε μέρα (every day), it clearly means a habitual action:

I wait for the bus here every day.

Because Greek usually does not need a subject pronoun when the verb ending already shows who the subject is.

περιμένω already means I wait.

So:

• περιμένω = I wait
• περιμένεις = you wait
• περιμένει = he/she/it waits

You would add εγώ only for emphasis or contrast, for example:

Εγώ περιμένω το λεωφορείο, όχι εκείνος.
I’m waiting for the bus, not him.

Because κάθε means every / each and normally goes directly before a singular noun, without an article.

So Greek says:

• κάθε μέρα = every day
• κάθε εβδομάδα = every week
• κάθε χρόνο = every year

This is completely normal Greek structure.

Because the Greek verb περιμένω usually takes a direct object.

So Greek says literally:

• περιμένω το λεωφορείο = I wait the bus

But in natural English, we say:

• I wait for the bus

This is just a difference between the two languages. With περιμένω, Greek normally does not need για here.

Greek uses the definite article more often than English does.

Here, το λεωφορείο sounds natural because it refers to the bus as a known or expected thing in the situation.

So even if English sometimes drops the in similar expressions, Greek often keeps it.

No. Greek word order is fairly flexible.

This sentence is natural as:

Σε αυτό το σημείο περιμένω κάθε μέρα το λεωφορείο.

But other orders are possible, for example:

• Περιμένω το λεωφορείο σε αυτό το σημείο κάθε μέρα.
• Κάθε μέρα περιμένω το λεωφορείο σε αυτό το σημείο.

The basic meaning stays the same, but the emphasis changes slightly depending on what comes first.

Yes, it can.

σε αυτό το σημείο can be:

• literal: at this spot/place
• figurative: at this point in a discussion, process, or story

In this sentence, because it talks about waiting for a bus, the meaning is clearly literal: at this spot.

It is pronounced roughly le-o-fo-REE-o, with the stress on ρεί.

The accent mark shows the stressed syllable:

λεωφορείο

Greek learners often find this word long at first, but it is very common, so it becomes familiar quickly.
