Questions & Answers about Bataryanın kapasitesi ne kadar büyük?
How does ne kadar mean "how large" in this sentence?
Could I just say ne büyük instead of ne kadar büyük to ask "how big"?
No, because dropping kadar changes the phrase from a question to an exclamation! Saying ne büyük! means "How big!" or "What a big...!" To ask a genuine question about the size or degree of something, you must use ne kadar büyük.
Why do we need the suffixes -nın on batarya and -si on kapasite?
This is a definite noun compound linking two nouns to show possession. Batarya gets the genitive suffix -nın to mean "the battery's", and kapasite gets the third-person possessive suffix -si to mean "its capacity". Together, they form bataryanın kapasitesi (the battery's capacity).
Why isn't there a word for "is" at the end of the sentence?
In Turkish, the third-person present tense "is" is often implied without any suffix at all. You could technically add the "to be" suffix -tür to make it büyüktür, but leaving it off is very common and sounds completely natural in everyday questions.
