Indo-Aryan languages are a group of languages spoken in some parts of Asia, like India, Nepal, and Pakistan.
Let's say you and your friends want to talk to each other, but you come from different parts of the world and speak different languages. To communicate, you have to learn a new language that everyone can understand. Indo-Aryan languages work in a similar way.
These languages come from a long time ago when people in the area spoke Sanskrit. Over time, different regions developed different versions of Sanskrit that became the Indo-Aryan languages we know today.
Some of the most common Indo-Aryan languages are Hindi, Bengali, Punjabi, and Gujarati. Each language has its own unique sounds and words, but they all have some things in common. For example, they all use the same alphabet called Devanagari, which has a lot of squiggly lines and dots.
Indo-Aryan languages also have different levels of formality. You might use a more formal way of speaking if you're talking to someone older or in a professional setting, but a more casual way of speaking if you're talking to your friends or family.
Overall, Indo-Aryan languages are important for communication and understanding different cultures in the areas where they're spoken.
