First, compare France, Italy and Germany.

Italian is the best of the three languages. As for the inflections of French and German, both Latin languages need this kind of thing, while Italian is the simplest and most basic language in Latin languages, which is easy to read. How to write and read words is also very regular. To put it simply, learning Italian and then learning French and Spanish is basically a matter of memorizing words, because you will find that the grammar and sentence patterns are similar. Learning German is because between Latin and English, if English is good, it is not difficult to learn any of the three.

In addition, Russian ... is really difficult, and it is not widely used in spelling, pronunciation or grammar.

Japanese ... it's easy to start, but once you start to learn the usage of tense and case, it will become more and more difficult.

Difficulty angle: Italian is the simplest, easy to learn, easy to learn, and the most difficult to recite words.

However, from the perspective of future employment, there are relatively more people who can speak French, German and Japanese.

So if you want to learn Latin, I suggest you start with Italian.

I am studying in Italy now. I am learning three languages: Italian, French and Spanish.
