The Grammar-Translation method is a traditional method for teaching foreign languages that uses translation and grammar rules as the core activities. It originated in the late 19th/early 20th centuries for teaching Latin and Greek. Key features include using the native language for instruction, memorizing vocabulary lists and grammar rules, translating texts word-for-word, and focusing on the form and structure of language over communication. While easiest for teachers and least stressful for students, it is ineffective for teaching communication skills and comprehension.
