Hebrew hadn't been spoken as a regular language for thousands of years, and yet today the language is spoken in its modern form by nearly every Jewish Israeli. How did this happen? Who updated the language to its modern form and how was it taught and learned so quickly? Wouldn't teachers need to be trained and such? And how did so many people learn it so quickly? Immersion is a very important part of learning a language quickly which is one of the issues with learning less common languages.
