Linguistic development is the study of how language skills develop from infancy through adulthood. This area of research examines the processes and milestones involved in learning to understand and produce language, as well as the factors that influence language acquisition and proficiency. Researchers in this field may study the role of genetics, environment, social interaction, and cognitive abilities in language development. They may also investigate how language skills change over time and vary across different populations. Overall, linguistic development research aims to enhance our understanding of how humans acquire and use language, which has implications for education, communication, and cognitive development.
