Difficulty level of minority language learning

To say that there is no quantitative data in the ranking, here is just a general view:

Arabic->; Hebrew-> Hindi & Urdu-> Russian-> German-> Persian->; French-> Italian->; Spanish->; English

I can't scribble the data, but the following points are debatable.

1. Arabic and Hebrew are Semitic languages. Personally, Arabic is more difficult to learn than Greek and involves various dialects. Therefore, it is not objective to say that Greek is more difficult to learn than Arabic in the rankings.

2. The biggest difference between Hindi and Urdu lies in the alphabet, Brahma culture and Islamization. As for grammar and vocabulary, I'm afraid it's quite or slightly greater than the difference between Britain and America?

Third, people who have no foundation in German and Russian think that Russian is more difficult, first of all, Cyrillic letters, followed by hexagrams, or Slavic languages. In contrast, German, after all, is a Latin alphabet. It has only four cases, and it is a Germanic language family like English.

Fourth, Persian, I don't know about this, but it can be said that it is more difficult, mainly using Arabic letters, but it belongs to the Indo-European language family after all.

French, Italian and western languages are almost the same. They are all Romanesque languages. French is first placed in the most difficult position, because its pronunciation requires high accuracy, and Italian is slightly better than western languages. As for grammar and vocabulary, it's actually similar. Italian and the west have their own difficulties, so it is necessary to compare them. Italian is more difficult.

6. English is the easiest to learn. First, because we have studied for many years, we are used to it. Second, it is the most simplified German. Even compared with romance, there are many simplifications.

For many people in China who speak English as their first foreign language, French, Italian and Spanish are the easiest to learn. Of course, French is a little more difficult. Because Persian is an Arabic alphabet, many people may find it difficult at first. As far as my superficial understanding is concerned, its grammar is relatively simple, similar to English grammar, and tends to be comprehensive. Most beginners may find Russian more difficult than German. In fact, I think the harder it is to learn German. Its grammatical features are thin, broken and troublesome, which is completely opposite to its powerful pronunciation. Hindi is actually not that scary, but the biggest difficulty is: 1. Sanskrit words. 2. Grammar is not complicated, but a little complicated. Arabic is undoubtedly the most difficult language to learn in the world, which is manifested in writing system, pronunciation, vocabulary, grammar and many dialects.

So, I think:

Grade one: Arabic, Hebrew, Sanskrit, Finnish

Second grade: Lithuanian and Uralic.

Grade 3: Hindi & Urdu, German, Russian and Greek.

Fourth grade: Persian, French, Italian, Spanish, Germanic.

Grade 5: English
