CAU

Cau is a term with multiple meanings in different languages, but it is best known in Vietnamese contexts. In Vietnamese, the word cau is commonly written as cầu with diacritics and means bridge. The same spelling without diacritics is often used in digital text to represent the same word. The term can also appear as a verb meaning to wish, to pray, or to request, depending on context.

In Vietnamese toponymy, cầu is frequently found in the names of bridges and places, reflecting the cultural importance of connectivity. Notable examples include Cầu Giấy District in Hanoi, which derives its name from a historical bridge, and the Long Biên Bridge, a historic bridge in Hanoi that includes the word cầu in its name. Such usage illustrates how the term functions as a descriptive element in geographic names.

Beyond Vietnam, cau can appear in other linguistic contexts as a transliteration or as part of proper names. In some cases, CAU may also be used as an acronym or initialism in various organizations, projects, or terms, depending on language and field. Because of this variety, the meaning of cau is highly context-dependent and not fixed to a single definition.

Overall, cau most commonly relates to the concept of a bridge in Vietnamese usage, and it also appears in place names and, less predictably, in other linguistic or organizational contexts. Related topics include bridges and toponymy.
