L2 writing, or second language writing, is a research area that focuses on the study of writing in a second language. This field explores the acquisition, development, and use of writing skills among individuals who are learning a second language. Researchers in this area examine factors that influence L2 writing proficiency, such as language proficiency, cultural background, and instructional methods. They also investigate how L2 writing differs from first language writing and explore ways to enhance writing instruction for second language learners. Ultimately, the goal of L2 writing research is to improve teaching practices and help individuals become more effective writers in their second language.
