Okay, imagine you are playing with building blocks and you stack them up to make a tall tower. Now imagine you can't quite reach the top of the tower and you need someone taller to help you. That's kind of like how the Ottoman Turkish language came to be.
A long, long time ago, there were people who spoke a language called Old Turkic. But as time went by, some new people came and mixed with the Old Turkic speakers. These new people spoke a language called Arabic and they brought new words and sounds with them.
So, just like how you needed someone taller to reach the top of your tower, the Old Turkic speakers needed the Arabic speakers to help them communicate better. They started using a mix of Old Turkic and Arabic, which became known as Ottoman Turkish.
Ottoman Turkish was used by the rulers of the Ottoman Empire, which was a big empire that lasted for many years. They used this language in official documents, courts, and for talking to important people.
Over time, Ottoman Turkish changed and evolved, just like your building block tower might change if you added more blocks or rearranged them. It got newer words and different ways of saying things, which made it easier for people to use.
Today, Ottoman Turkish isn't really spoken the way it used to be. But it's still an important part of history and can give us clues about how people used to live and talk a long time ago.
