Learn Turkish: Çocuklar şimdi mutfakta. - The children are in the kitchen now.

The word mutfak (kitchen) ends in a hard consonant (k). In Turkish, when a word ends in a hard, voiceless consonant (like p, ç, t, k, s, ş, h, f), suffixes that normally start with d change to t to make pronunciation smoother. So, the "in" suffix -da becomes -ta, giving us mutfakta.

Where is the word for "are" in this sentence?

Turkish often doesn't use a specific word for "am/is/are" when stating facts or locations. The sentence literally translates to "Children now kitchen-in." The "are" is simply understood from the context.

Why doesn't mutfakta have a plural suffix like -lar at the end?

You could add -lar and say Çocuklar şimdi mutfaktalar, but it's not strictly necessary. Because the subject (Çocuklar) already has the plural ending, Turkish often drops the plural suffix on the final word to avoid repetition.

Why is şimdi (now) in the middle instead of at the end like in English?

Time words in Turkish usually go near the beginning of the sentence, right after the subject. In English, we often put "now" at the end, but in Turkish, the standard flow is Subject (Çocuklar) + Time (şimdi) + Place/Predicate (mutfakta).
