What is the Relationship between descriptive linguistics and language teaching?

Descriptive linguistics provides an understanding of language structure and usage, which can inform language teaching practices by helping teachers create effective language lessons. By analyzing the components of a language, teachers can better address students' needs, tailor instruction to their abilities, and facilitate language learning. In essence, descriptive linguistics offers insights into how languages work, aiding language teachers in effectively imparting language knowledge and skills to their students.
