What is the abbreviation for South?

The abbreviation for South is represented by the letter "S." This abbreviation is commonly used in various contexts, such as mapping, navigation, or when indicating directions. It is a standard practice to use a single letter to denote cardinal directions to simplify communication and to keep information concise.

While "So" and "Sou" might seem like logical abbreviations based on the word itself, they do not follow the accepted conventions for directional abbreviations. "St" typically stands for "Street," and thus does not relate to the direction at all. Therefore, using "S" as the abbreviation for South aligns with established conventions in geography and map reading.
