Language engineering is like teaching a computer how to understand and use language, just like how your teacher helps you learn and use language.
First, we give the computer a big list of words called a dictionary, just like how you learn words from a book or a grown-up. The computer then learns how these words are used together to form sentences and communicate ideas, just like how you learn to use words to tell a story or ask for something you want.
But because language can be very complicated, we need special rules to help the computer understand how to use language correctly. These rules are called grammar rules, and they tell the computer things like which order to put the words in and what sounds different letters make.
Once the computer understands language, we can use it to do all sorts of cool things like translate languages for us, analyze big sets of data, or even chat with us like a friend!
