[Salvanas]

All languages are important when looked at a historical view.

Sumerian, Hieroglyphics, Latin, Akkadian, and loads more.

Putting languages into a list of "importance" is folly, and is a way to handicap yourself. If I could, I'd love to learn all the ancient languages, and all current languages. Unfortunately, that's not a possibility.

Language is a form of communication. Communication is the most important thing on the earth.
