Applied Linguistics is the study of how language is used in real-world situations. It combines knowledge from various fields, such as sociology, psychology, and education, to address practical issues related to language. This can include teaching languages, improving communication in diverse settings, and understanding language disorders. One key area of Applied Linguistics is language acquisition, which explores how people learn languages at different ages. Researchers in this field may develop teaching methods or materials that help learners acquire new languages more effectively. Overall, Applied Linguistics aims to solve language-related problems and enhance communication in society.
