Why do children’s brains learn languages faster than adult brains?

Young brains are especially plastic, meaning they adapt quickly to new sounds, grammar patterns, and meanings. Children also tend to hear language in rich, repetitive contexts, which helps them map words to the world around them. Adults can still learn languages well, but they often rely more on conscious study and less on effortless pattern absorption. The brain remains capable of learning across life, yet early childhood is a particularly efficient period for picking up pronunciation and structure. That is why young learners often acquire a native-like accent more easily than adults.
