Language development is the process of learning to understand and use language. It includes speaking, listening, reading, and writing. Children begin learning language from the sounds and words they hear around them. Families, caregivers, and communities play an important role in this process.

This development happens in all cultures and languages across the world. Some children grow up learning more than one language at the same time. Language can be spoken, written, or signed, such as in sign languages used by deaf communities. Schools and social interactions also support language growth.

Language development begins in early childhood and continues over time. Babies start by recognizing sounds, then move to words and sentences as they grow. Older children expand their vocabulary and learn new ways to communicate. This process continues throughout life as people learn new languages or forms of expression.
