Google Translate is like a magic box that helps people who speak different languages understand each other. When you type in words or sentences in one language, like "Hola," which means "Hello" in Spanish, Google Translate uses a computer program to change those words into another language, like English, where "Hola" would become "Hello".
The computer program works by looking at patterns and rules for how words are put together in different languages. It also compares the new sentence to other similar sentences that people have already translated, to try and figure out the best way to say it.
Sometimes, the translation might not be 100% perfect or make complete sense, because languages can be very different from each other. But, Google Translate is constantly learning and improving, so it can help more and more people communicate with each other, even if they speak different languages.
