Ben okulun önünde arkadaşımı bekliyorum.

Yes. The ending -um in bekliyorum already tells you the subject is I. That means Ben is optional here.

Speakers often add Ben for emphasis, contrast, or clarity. In everyday Turkish, Okulun önünde arkadaşımı bekliyorum would also be completely natural.

Turkish does not have a definite article like English the. Definiteness is usually understood from context, possession, and case marking.

So okulun naturally gives the sense of of the school, and arkadaşımı is already definite because it means my friend and is marked as a specific object.

Because Turkish beklemek works differently from English to wait for. In Turkish, beklemek takes a direct object.

So arkadaşımı bekliyorum literally looks closer to I am waiting my friend, but that is the normal Turkish structure for I am waiting for my friend.

Because Turkish says the front of the school using a genitive-possessive structure.

Here:

• okul = school
• okulun = of the school

That -un ending is the genitive suffix. It shows that the next word belongs to or is associated with the school.

It breaks down like this:

• ön = front
• önü = its front
• önünde = at/in/on its front

So okulun önünde literally means at the school’s front, which is how Turkish normally expresses in front of the school.

The -de part is the locative suffix, meaning in / at / on. But when it comes after a possessed form like önü, Turkish inserts a buffer n.

So:

• önü = its front
• önünde = at its front

That is why you see -nde here.

Not exactly. Turkish usually does not build these expressions the same way English does.

Instead of a separate preposition, Turkish often uses a noun of location such as ön meaning front, together with suffixes. So okulun önünde is structurally more like at the school’s front than an English-style prepositional phrase.

This same pattern appears in:

• evin arkasında = behind the house
• masanın üstünde = on the table
• kapının yanında = next to the door

arkadaşım means my friend by itself. In this sentence, though, it is the direct object of beklemek, and it refers to a specific person, so it takes the accusative ending.

Breakdown:

• arkadaş = friend
• arkadaşım = my friend
• arkadaşımı = my friend as a specific direct object

So the final -ı is the accusative suffix.

It is the present continuous, meaning I am waiting.

Breakdown:

• bekle- = wait
• -iyor = present continuous
• -um = I

So bekliyorum means I am waiting.

The present continuous suffix is -iyor / -ıyor / -uyor / -üyor. When it attaches to a verb stem ending in a vowel, that final vowel often drops.

So:

• bekle- + -iyor
• becomes bekliyor

That is why you get bekliyorum, not bekleiyorum.

Yes. Turkish word order is flexible, although the verb usually stays near the end.

This sentence is natural as it stands, but other orders are also possible, such as Arkadaşımı okulun önünde bekliyorum. The basic meaning stays the same, but the emphasis can shift depending on what the speaker wants to highlight.

Because Turkish uses vowel harmony. Many suffixes have different versions, and the form changes to match the vowels around them.

In this sentence:

• okul-un
• ön-ü
• arkadaş-ım-ı
• bekliyor-um

These are all normal vowel-harmony patterns. It may look complicated at first, but it actually makes Turkish suffixes very regular once you get used to them.
