[DonRotolo]

Uber is actually "Ueber" - the 'e' after the U is placed there instead of the two dots on top (Umlaut) when typing on an English language keyboard.

Über is how it is really spelled

It literally means "over" as in something that above another thing, either physically above, or above socially, or hierarchically.

In common English usage it can be compared to "super".
