Otobüs saat sekizde geliyor.

Because -de is the Turkish locative ending, and with time expressions it often means at/in/on depending on context. So:

• sekiz = eight
• sekizde = at eight o’clock

In this sentence, sekizde tells us the time when the bus arrives.

Yes, sekizde already gives the time, so saat is not always strictly necessary.

• Otobüs sekizde geliyor. = The bus is coming at eight.
• Otobüs saat sekizde geliyor. = The bus is coming at eight o’clock.

Here, saat helps make the time expression feel more explicit and natural, like saying at eight o’clock rather than just at eight.

Geliyor comes from the verb gelmek, meaning to come.

The form geliyor is the present continuous, so literally it means:

• is coming

But in Turkish, this form is also often used for scheduled future events, especially things like buses, trains, lessons, or appointments. So here it can naturally mean:

• The bus is coming at eight
• The bus arrives at eight

Both are good ways to understand it.

Turkish often uses the present continuous for planned or scheduled future events, just like English sometimes does.

Compare:

• English: The bus is coming at eight.
• Turkish: Otobüs saat sekizde geliyor.

This sounds natural for something arranged or expected. You could use a future form in some contexts, but geliyor is very common for schedules.

Yes. Even though geliyor literally looks like is coming, in context it can easily mean arrives.

For transport schedules, English often prefers arrives, while Turkish still commonly uses geliyor. So:

• Otobüs saat sekizde geliyor.
• Possible translations:
  • The bus is coming at eight.
  • The bus arrives at eight.

Turkish does not have articles like a or the.

So otobüs can mean:

• a bus
• the bus
• sometimes just bus, depending on context

The exact meaning is understood from the situation. In this sentence, English usually needs the bus, but Turkish does not mark that separately.

The sentence is:

• Otobüs = bus
• saat sekizde = at eight o’clock
• geliyor = is coming / comes

So the order is:

Subject + time expression + verb

This is very natural in Turkish. Turkish often places the verb at the end of the sentence.

Yes, Turkish word order is flexible, although the verb usually stays at the end. For example:

• Otobüs saat sekizde geliyor.
• Saat sekizde otobüs geliyor.

Both are possible, but they may shift emphasis slightly. The original version sounds neutral and natural.

This is because of vowel harmony.

The word sekiz has the vowel i, which is a front vowel, so the locative ending appears as -de rather than -da.

Compare:

• evde = in the house
• okulda = at school
• sekizde = at eight

So the vowel in the suffix changes to match the word.

The locative suffix can appear as -de, -da, -te, or -ta.

Which one you get depends on two things:

1. Vowel harmony → e/a
2. Consonant voicing → d/t

Since sekiz ends in z, which is a voiced consonant, the suffix uses d:

• sekiz + de → sekizde

If the word ended in a voiceless consonant, you might get t instead.

It is a very common time pattern.

You will often see:

• saat birde = at one o’clock
• saat üçte = at three o’clock
• saat yedide = at seven o’clock
• saat sekizde = at eight o’clock

So yes, saat + number + locative ending is a standard way to express clock time.

Yes, but then the meaning changes slightly.

• Otobüs geliyor. = The bus is coming.
• Otobüs saat sekizde geliyor. = The bus is coming at eight.

Without saat sekizde, the sentence no longer gives a specific time.

A simple approximate pronunciation is:

oh-toh-BUUS saat seh-kiz-DEH geh-lee-YOR

A few notes:

• ö in otobüs is like the vowel in German schön or French peu
• ü is a front rounded vowel, similar to German ü
• Stress in geliyor is usually toward the end: geliYOR
• sekizde is pronounced smoothly as one word: se-kiz-de

Yes, but it changes the feel.

• Otobüs saat sekizde geliyor. = The bus comes / is coming at eight.
  This sounds natural for a schedule or expected event.

• Otobüs saat sekizde gelecek. = The bus will come at eight.
  This can sound a bit more explicitly future-oriented.

For timetables and routine arrivals, geliyor is often the more natural choice.

Yes. Otobüs is the subject, because it is the thing doing the action of coming.

So the structure is:

• Otobüs = subject
• saat sekizde = time phrase
• geliyor = verb

That makes the whole sentence straightforward: The bus is coming at eight.
