Is the most rigorous language French or German? Please talk about their respective advantages.

Grammatically speaking, German is more rigorous. German grammar is very complicated and clearly divided. For example, part of speech has yin and yang, while French is yin and yang. In addition, there are more varieties of German than French. In a German sentence, as long as the verb position conforms to the grammar, no matter how you disturb other components of the sentence, you can understand the meaning of the sentence accurately. For example, in German, I love you. You can say that you love me, but the original meaning is ich liebe dich and dichliebeidich. These two sentences have the same meaning. But the French can't do it. In addition, at present, I also found that there are no more than 10 words with the same pronunciation in German. I can't do this in French either. But German is so complicated that it takes a lot of brains and energy for foreigners to understand the meaning of sentences, and it is blunt to say. Moreover, French itself is actually very rigorous, and the documents written in French are rarely vague, and it is much better than German, and there is no breath (for example, the pronunciation of China breath, so French does not spit). Therefore, the official documents between governments all over the world use French uniformly.
