Language development is the process through which children acquire the ability to understand, communicate, and use language effectively. It is one of the most significant aspects of child development, as it influences cognitive growth, social interaction, emotional expression, and academic achievement.

Language development begins in infancy. Newborns communicate through crying and gradually respond to voices, sounds, and facial expressions. By six months, infants start babbling and experimenting with different sounds. Around one year of age, they begin speaking simple words such as "mama" and "dada." Between one and three years, vocabulary expands rapidly, and children begin forming two- to three-word sentences.
