Questions & Answers about Ben toplantı tutanağı yazıyorum.

Why is the personal pronoun Ben used here when the verb ending already shows “I”?

In Turkish the subject is usually clear from the verb ending, so you can drop Ben:
• (Ben) toplantı tutanağı yazıyorum.
Here yazıyorum already means “I am writing.”
Ben appears only for emphasis, contrast or clarity (e.g. to stress that you are the one writing).

What does toplantı tutanağı mean and how is that phrase built?

Toplantı tutanağı means meeting minutes or meeting protocol. It’s a noun–noun compound:
• toplantı = meeting
• tutanak = minutes / protocol
In Turkish compounds, the first noun modifies the second, and the second noun takes a 3rd-person possessive suffix to signal “of” or “type.” So tutanak + ı becomes tutanağı, literally “the protocol of (a) meeting.”

Why does tutanağı end in -ı? Is that the object’s accusative ending?

No, the -ı on tutanağı is the 3rd-person singular possessive (its).
• As part of the compound toplantı tutanağı, it marks “minutes of the meeting.”
If you wanted to mark that compound as a definite object, you would add another accusative -nı, giving tutanağını (“the meeting minutes” as a specific set you’re writing).
