Learn Turkish: Bu vizyoner kadın eğitimde bir devrim başlattı. - This visionary woman started a revolution in education.

The verb başlamak (to begin) is normally intransitive, meaning something starts on its own (e.g., "the lesson started"). Because she is starting something else (a revolution), you need the causative suffix -t, turning it into başlatmak. So başlattı means "she caused it to start" or "she started it."

Can the locative suffix -de be used for abstract concepts like eğitim (education)?

Yes! The locative suffix -de/-da (in/on/at) is not just for physical locations. Just like in English, you use it to say something happens "in education" (eğitimde), "in science" (bilimde), or "in business" (işte).

How could we use the lesson's target word hatta to expand on this sentence?

While hatta (even / in fact) isn't used in this exact sentence, it is perfect for escalating this idea in a follow-up clause. For example, you could add to her achievements: Bu vizyoner kadın eğitimde bir devrim başlattı, hatta yeni okullar açtı. (This visionary woman started a revolution in education; in fact, she opened new schools.)

Why does bir come directly before devrim?
