Which field studies how linguistics can address real-life problems across psychology, sociology and education?

• A. Applied linguistics
• B. Descriptive linguistics
• C. Theoretical linguistics
• D. Historical linguistics

Answer: (A)

Applied linguistics is about using linguistic knowledge to address real-world problems across psychology, sociology, and education. It bridges theory and practice, studying how language works in real contexts, how people learn and use languages, how language is assessed, and how policy and social factors influence communication. In education, it informs methods for teaching languages, literacy development, and language testing. In psychology, it investigates language processing, cognition, and how people acquire languages. In sociology, it looks at language attitudes, bilingualism, social identity, and how discourse reflects and shapes society. This practical, problem‑oriented focus sets it apart from other branches that describe language structure (descriptive), delve into abstract systems (theoretical), or study language change over time (historical).
