Über
Über (German pronunciation: [ˈyːbɐ], sometimes written uber ) in English language publications, is a German language word meaning "over", "above" or "across". It is an etymological twin with German ober, and is cognate (through Proto-Germanic) with English over, Dutch over and Icelandic yfir, among other Germanic languages. It is also distantly cognate to both Latin super and Greek ὑπέρ (hyper), through Proto-Indo-European. It is relatively well-known within Anglophone communities due to its occasional use as a hyphenated prefix in informal English, usually for emphasis. The German word is properly spelled with an umlaut, while the spelling of the English loanword varies.
In German
In German, über is a preposition, as well as being used as a prefix. Both uses indicate a state or action involving increased elevation or quantity in the physical sense, or superiority or excess in the abstract.
As a preposition, über's meaning depends on its context. For example, über etwas sprechen – to speak about something, über die Brücke – across the bridge.
