In general, Khan Academy is a great resource to help me learn ahead and further my depth of understanding for subjects like math/science but when it comes to language there just isn’t anything available. I would really love to see classical languages like Latin and Greek added, but it would at least be nice to have some basic languages like Spanish, French, Chinese, and German. And in all honesty it might be best to start with the AP Prep courses for these languages and then add stuff for beginners later. Latin is proven to help people in so many different areas of study, by just learning basic Latin I was able to enhance my learning in all of my other classes. Latin is such a foundation for so many things and another advantage to making a Latin course vs a modern language course is that it is primarily just the grammar and Vocab needed for translation. I’m fact the whole AP Latin course revolves around sight translation and comprehension of the like 800 lines you need to know. Latin also use to be required as one of the core subjects you had to take and there is still a huge classical community that would benefit from this course addition. There are also significantly less materials available to those who choose to learn Latin as their foreign language and honestly a khan academy course would help Latin students a lot, even the Duolingo course is so short it feels like you aren’t getting anywhere in the language, meaning that Khan Academy could put out the first interactive course for Latin that gets to the grammar past what you learn pretty much in the first semester of high school Latin.
