The letter "ß," known as the Eszett or sharp S, is a unique character in the German alphabet. It represents a voiceless sibilant sound, similar to the English "s" in "see." The Eszett is used in specific contexts, primarily in Germany and Switzerland, and is often found in words like Straße (street) and Fuß (foot). Unlike the standard Latin letters, "ß" does not have an uppercase form in traditional usage. However, in recent years, some style guides have introduced an uppercase version, "ẞ," for clarity in all-caps writing. The letter plays a significant role in distinguishing meanings in the German language.
