Questions & Answers about Ben her sabah yoğurt yerim.
Why doesn't "yoğurt" have an accusative ending like "yoğurdu"?
Because it refers to yogurt in general, not a specific yogurt. In Turkish, if you are talking about eating "the yogurt" (a specific one), you would use the accusative case and say yoğurdu. Since it's just general "yogurt", it stays in its plain dictionary form.
How is the verb "yerim" formed?
It comes from the verb yemek (to eat). Since this is a habit that happens every morning, we use the simple present tense, also known as the aorist. For verbs ending in a vowel like the root ye-, we just add -r to show this tense, followed by the personal ending -im for "I". So it becomes ye-r-im.
Do I have to include "Ben" at the beginning of the sentence?
No, it is optional. The ending -im on yerim already tells us "I" am doing the eating. Using Ben here just adds a little bit of emphasis, like saying "As for me, I eat yogurt."
Why isn't "sabah" plural if I eat yogurt every morning?
In Turkish, the word her (every) is always followed by a singular noun. You say her sabah (every morning), just like in English, and you never use the plural form her sabahlar.
