sau

Sau may refer to several different meanings depending on language and context.

In Romanian, sau is the conjunction meaning or, used to connect two or more alternatives in a sentence.

In Vietnamese, sau means after or behind. It functions as a preposition or adverb and commonly appears in phrases indicating temporal order or spatial position, such as in compounds like sau đó meaning after that.

In international coding and data systems, SAU is the ISO 3166-1 alpha-3 code for Saudi Arabia, used to represent the country in tables, statistics, shipping, and other global data contexts.

As an acronym, SAU can appear in various organizations or designations and is not tied to a single universal meaning. The term sau thus spans linguistic usage in Romanian and Vietnamese, as well as standardized codes in international reference systems.
