Learn Turkish: Fırın cumartesi kapalı değil. - The bakery is not closed on Saturday.

In Turkish, you usually do not need a preposition like "on" for days of the week. When you want to say something happens on a specific day, you can just state the name of the day. So, cumartesi means both "Saturday" and "on Saturday".

I noticed cumartesi looks a lot like cuma (Friday). Are they related?

Yes! Cuma means Friday, and the word ertesi means "the day after". When you put them together, they form cumartesi, which literally means "the day after Friday".

Why is there no word for "The" before Fırın?

Turkish does not have a definite article like the English word "the" as a separate word. Depending on the context, a simple noun like Fırın can mean "a bakery", "bakery", or "the bakery".

Why is değil at the very end of the sentence?

The word değil means "not" or "is not" for nouns and adjectives. In Turkish, verbs and negative words usually go at the very end of the sentence. Since it negates the word "closed" (kapalı), it is placed right after it.
