Learn Hardcore Turkish: Ben her şeyi biliyorum.

In Turkish, the verb ending already indicates the subject, so Ben (meaning I) can often be omitted. However, it is included here for clarity or emphasis—perhaps to contrast the speaker with someone else or to ensure that the listener clearly understands who is speaking.

How is the phrase her şeyi structured and what does each part mean?

The phrase breaks down as follows: her means every, şey means thing, and the -i at the end is the accusative case marker. Together, her şeyi literally translates to every thing, which is understood as everything.

Why does her şey take the accusative suffix -i in this sentence?

In Turkish grammar, definite direct objects require the accusative case marker. Since her şeyi refers to a specific, complete set of things—that is, everything—the suffix -i is added to indicate that the noun phrase is a definite direct object of the verb.

What is the grammatical structure of the verb biliyorum?

Biliyorum comes from the verb bilmek, meaning to know. The suffix -yorum is used to form the first-person singular present tense, indicating that the speaker is performing the action of knowing. So, biliyorum means I know.

Can the subject Ben be omitted in this sentence? Why might it be included explicitly?

Yes, the subject Ben can be omitted because the verb ending -yorum already signals the first-person singular. It is included explicitly here to emphasize the subject or to remove any potential ambiguity about who is doing the knowing.
