Questions & Answers about Öğretmene günaydın dedim.

Why is it öğretmene and not just öğretmen?

Because öğretmene has the dative case ending -e, which often means to or toward.

• öğretmen = teacher
• öğretmene = to the teacher

With demek in this kind of sentence, the person you say something to is usually marked with the dative case.

What exactly does the ending -e mean here?

Here, -e marks the recipient of what is being said.

So in:

• Öğretmene günaydın dedim

the structure is basically:

• to the teacher
  • good morning
    • I said

This is very common in Turkish. Many verbs use case endings instead of separate words like to.

Why is the verb dedim and not something like söyledim?

Turkish commonly uses demek for expressions such as greetings, short statements, and direct speech.

So:

• günaydın demek = to say good morning
• merhaba demek = to say hello

While söylemek also means to say / tell, demek is especially natural when reporting the exact word or phrase someone said.

So günaydın dedim sounds very natural.
