One thing we can be sure of is that this list is not complete and never will be because language is developed by humans as a means of communication and will definitely continue to develop in the future . Maybe there will be more or less differences and all current or future differences are related to people's culture and mentality. That's why there are many varieties of the difficult-to-define term “Standard English.” In conclusion, you need to understand the differences between each standard language to avoid misunderstandings, use the language correctly, and show respect for that language's native culture.
