Questions & Answers about Ben bulaşık deterjanı alıyorum.

Do I need to include the pronoun Ben, or can I just say Bulaşık deterjanı alıyorum?

You can drop Ben. The verb ending in alıyorum already shows the subject is “I.” Using Ben adds emphasis or contrast (I, as opposed to someone else).

Does alıyorum mean “I’m buying,” “I’m taking,” or “I’m getting”?

All are possible; almak is broad (“to take/receive/get/buy”). In a shopping context like this, it naturally reads as “I’m buying.” Context disambiguates.

Why does bulaşık deterjanı end with -ı? Is that the accusative?

No. In Turkish noun–noun compounds, the second noun takes a 3rd‑person possessive suffix: bulaşık deterjanı = “dish detergent” (literally “dishes’ detergent”). That -ı here is possessive, not accusative. Compare: elma suyu (“apple juice”).

Shouldn’t a direct object take the accusative -(y)ı?

Only if it’s definite/specific. Here it’s indefinite (“some dish detergent”), so no accusative. Definite object: bulaşık deterjanını alıyorum = “I’m buying the dish detergent (the one we know about).”

So how do I say “I’m buying the dish detergent we talked about”?
