Bu sabah otobüs seferi gecikti.

Bu sabah means this morning.

In Turkish, bu = this, and sabah = morning, so together they literally mean this morning.

A learner might expect bugün sabah, but that is not the most natural standard phrasing. Turkish usually says:

• bu sabah = this morning
• bu akşam = this evening
• bu gece = tonight

So bu sabah is the normal way to express that time phrase.

Otobüs seferi is a noun phrase meaning something like:

• bus service
• bus run
• bus trip
• scheduled bus departure/journey

The exact English translation depends on context.

Here:

• otobüs = bus
• sefer = trip, run, service, expedition
• seferi = the form used in this compound

So otobüs seferi is not just a bus; it refers more specifically to a bus service/journey/departure.

This is because Turkish commonly forms noun compounds with a special ending on the second noun.

In otobüs seferi:

• otobüs modifies sefer
• the second noun takes the 3rd person possessive ending: -i

So:

• otobüs seferi = bus service / bus trip

This is a very common pattern in Turkish. Compare:

• okul kapısı = school door
• şehir merkezi = city center
• yaz tatili = summer vacation

Even though it looks a bit like possession in English grammar terms, it often just makes a compound noun.

No. In this sentence, the -i in seferi is not the accusative case.

It is part of the noun compound otobüs seferi.

That matters because otobüs seferi is the subject of the sentence, not the object. The thing that was delayed is the bus service itself.

So the structure is:

• Bu sabah = time expression
• otobüs seferi = subject
• gecikti = was delayed / was late

If it were accusative, we would expect it to be the direct object of a verb, but that is not what is happening here.

Gecikti is in the simple past tense.

It comes from:

• gecikmek = to be late, to be delayed
• stem: gecik-
• past ending: -ti

So:

• gecikti = it was delayed / it was late

The -ti past ending appears here instead of -di because of consonant devoicing: the stem ends in k, so the past suffix begins with t rather than d.

Turkish verbs often cover a range that English splits into several expressions.

Gecikmek can mean:

• to be late
• to arrive late
• to be delayed

So in this sentence, English naturally translates it as was delayed, because we are talking about a bus service.

Depending on context, gecikti could also be understood as:

• was late
• arrived late

But for transportation, was delayed is usually the best translation.

Turkish does not have articles like English a/an and the.

That means Turkish often leaves definiteness to be understood from context.

So otobüs seferi could be understood as:

• the bus service
• a bus service
• the bus run

In this sentence, context usually makes it feel like a specific bus service, so English often uses the.

Turkish word order is often Subject-Object-Verb, and the verb commonly comes at the end.

In this sentence:

• Bu sabah = time expression
• otobüs seferi = subject
• gecikti = verb

So the sentence is structured very naturally for Turkish.

A more literal English-like breakdown would be:

• This morning, the bus service was delayed.

Turkish often places time expressions near the beginning, especially when setting the scene.

Yes, Turkish word order is flexible, but changing it changes the emphasis.

For example:

• Bu sabah otobüs seferi gecikti. = neutral, natural
• Otobüs seferi bu sabah gecikti. = puts a bit more focus on this morning
• Gecikti bu sabah otobüs seferi. = possible in special contexts, but much less neutral

So the original sentence is the most standard everyday order.

It is singular.

There is no plural ending such as -ler / -lar, so it refers to one bus service/run/trip.

If it were plural, it might be something like:

• otobüs seferleri = bus services / bus runs

So Bu sabah otobüs seferi gecikti refers to one bus service being delayed.

Yes, but it would mean something slightly different.

• Otobüs gecikti = The bus was late / delayed
• Otobüs seferi gecikti = The bus service/run/departure was delayed

The second version sounds a bit more formal or transport-system-oriented. It refers to the scheduled service, not just the physical bus vehicle.

So both are possible, but they are not exactly the same in nuance.

Sometimes, but gecikti is better here.

Compare:

• gecikmek = to be delayed / be late
• geç kalmak = to be late

For transport services, gecikmek is especially natural:

• Otobüs gecikti.
• Tren gecikti.
• Uçak gecikti.

Geç kaldı is more often used for people:

• Okula geç kaldım. = I was late to school.
• Toplantıya geç kaldı. = He/She was late to the meeting.

So in this sentence, gecikti is the more idiomatic choice.

A simple pronunciation guide is:

Boo sa-bah o-to-bues se-fe-ri ge-jik-ti

A few notes:

• bu sounds roughly like boo
• sabah = sa-bah
• otobüs has ö, a front rounded vowel; English does not have an exact match
• c in Turkish is pronounced like English j in jam, so gecikti starts with a ge-jik- sound
• stress in Turkish is often fairly even, but in many phrases the final syllable tends to be prominent unless the word is an exception

A more careful approximation: bu saBAH otobüs sefeRI geCİKti

The dictionary form is gecikmek.

Turkish dictionary verbs usually end in -mek or -mak.

So:

• gecikmek = to be late / to be delayed
• gecikti = was delayed / was late

When learning Turkish, it helps to identify:

• verb stem: gecik-
• infinitive ending: -mek
• past ending here: -ti

That makes it easier to recognize related forms like:

• gecikiyor = is being delayed / is running late
• gecikecek = will be delayed
• gecikmedi = was not delayed
