Katharevousa

Katharevousa is a fancy word that people use to describe a special type of Greek language that was used in Greece many years ago. It's kind of like a "fancy" way of speaking and writing, and it was used in important documents and in the government. It was also taught in schools and colleges, so people who knew Katharevousa were thought to be very smart and educated.

The reason why Katharevousa is not used very much nowadays is because some people thought it was too hard to understand and not very useful in everyday life. They wanted to use a simpler way of speaking and writing that everyone could understand, so they started using a different type of Greek called Demotic. This new type of Greek was easier to learn and use, so it became more popular among people.

Nowadays, Katharevousa is still sometimes used in official documents and in certain situations, but Demotic is the language that most people use in their daily lives.
