Language learning is the process of acquiring a new language or improving one's proficiency in a second language. It involves developing skills in speaking, listening, reading, and writing in the target language. Research in this area examines various factors that influence language acquisition, such as age, motivation, aptitude, and learning strategies. It also explores different methods and approaches to teaching and learning languages, as well as the impact of technology on language learning. Overall, the goal of language learning research is to enhance our understanding of how individuals acquire and use languages, and to improve language learning outcomes for learners of all ages and backgrounds.
