Proto-Indo-Aryan language
Proto-Indo-Aryan language is a very old language that people spoke a really long time ago way before you or I were born. It is a special language that is considered the ancestor of many of the languages that people speak today, like Hindi and Bengali.
Imagine that you have a big family tree with many branches that represent different members of your family. Proto-Indo-Aryan language is like the very first branch on this tree - it's the oldest ancestor that many other branches (or languages) come from.
Long, long ago, some people started using a special way of speaking that was different from other people's ways of speaking. Over time, this way of speaking grew and changed, just like branches on a tree grow and change. Different groups of people spoke this way and their ways of speaking became different from each other. Eventually, their ways of speaking turned into different languages that we know today.
So basically, Proto-Indo-Aryan is a really, really old language that many other languages came from. It was the first branch on a big family tree of languages.
