Lingua Latīna per sē Illustrāta (LLPSI), the Latin textbook entirely in Latin, has a cult following. I understand the appeal. Personally, I love it, and am currently rereading it for the nth time. Still, I’m wary whenever people suggest LLPSI as the panacea to common pedagogical problems, or assume it’s the most appropriate resource to use when teaching Latin communicatively. Again, I understand, but LLPSI is still a textbook, and comes with every downside of using a textbook to teach communicatively.
