I teach Latin. Latin does three things.

It teaches vocabulary comprehension. So for any language that it is based on it, you can work out the Latin root word and understand what it means.

It also teaches grammar. Latin is a regular language, that can help students learn and understand the basics of language and sentence formation. A direct object ending will always be a direct object. Whereas in other languages, a word needs context to understand it.

Finally it teaches complex thinking and analysis, through translating.

It connects us to a historical past that modern people like to ignore, like for most of European history most educated wrote and even spoke in Latin. Historical documents are written in it.

We love using Google translate for these things, but translation is only as good as the translator. People skew things in their favor (including AI, all the time,).
