Young people tend to learn languages faster and more accurately than adults. In fact, children who learn a new language before about the age of twelve usually don't have any foreign accent at all. Let's take a look at two possible reasons why children learn languages much better than adults do. One reasons is that the child's brain is not fully developed. There are two sides of the brain, the left side and the right side. In adults, these two parts are separate. The left side is more analytical and more logical, while the right side is concerned about feeling s and things we see and hear. In children, the two sides of the brain are not fully separated. That makes them more flexible in learning languages.
