The Grammar Translation Method was originally developed for teaching Latin and Greek as dead languages. It focuses on learning grammar rules and translating texts word-for-word between the target language and native language. While it has disadvantages like not developing communicative skills, it still has value for certain goals and contexts. The method is based on theories of developing logical thinking and exposure to literature. It remains commonly used due to teacher skills required and ease of testing grammar knowledge through translation exercises. Overall, its appropriate use depends on the learning objectives and needs of the students.
