My understanding is that before Israel started existing very few people spoke Hebrew as it was basically a dead language, and then lots of immigrants who didn't know Hebrew came to Israel. Presumably, due to the formation of a functioning Israeli society made up of all these predominantly European immigrants who had professional jobs and stuff all of them most have learned how to speak a very high level of Hebrew in a very short space of time. My question is how did this happen? In addition, I don't know much about Hebrew but it seems like a fairly complex language that looks nothing like European languages both in text and in spoken tongue, why can't we do whatever the people of Israel did with their language with other foreign languages because they take ages to learn.
