Pimsleur is a language learning program developed by Dr. Paul Pimsleur in the 1960s. It focuses on auditory learning through a series of audio lessons that emphasize listening and speaking skills. The method is designed to help learners acquire a new language naturally, similar to how they learned their first language. The program is structured around a series of 30-minute lessons that introduce vocabulary and grammar in context. Each lesson builds on previous ones, reinforcing what has been learned. Pimsleur offers courses in numerous languages, making it a popular choice for travelers and language enthusiasts alike.
