The Capital Eszett: Everything You Need to Know About ẞ

For anyone diving into the complexities of the German language, the ß (known as the scharfes S, SZ, or Eszett) is already a unique challenge. It’s a character exclusive to German, appearing only at the end of words or within them—never at the start. But for a long time, the alphabet had a glaring omission: there was no capital version of this letter.

That changed recently. The capital ẞ is now an official part of the language, solving a long-standing headache for designers, lawyers, and anyone writing in all-caps. Here is the breakdown of why the capital Eszett exists and how to use it correctly.

Why the Capital Eszett Was Necessary

In the past, when writers needed to use all-capital letters (Versalien)—common in advertising, posters, and digital headlines—they had two choices for the scharfes S: they could either keep the small ß in the middle of a capitalized word or replace it with a double SS.

While replacing ß with SS seemed like a logical fix, it created significant linguistic ambiguity. In German, the difference between a single ß and a double ss can completely change the meaning of a word. When everything is written in uppercase, that distinction vanishes.

Solving the All-Caps Ambiguity

Without the capital ẞ, certain words become indistinguishable in all-caps, leading to potential confusion:

• MAẞE vs. MASSE: MAẞE refers to dimensions or measurements, whereas MASSE refers to mass, weight, or a crowd of people.
• BUẞE vs. BUSSE: BUẞE refers to a fine, penance, or atonement, while BUSSE is the plural form of “bus.”

Beyond general vocabulary, the capital ẞ is crucial for proper names. For instance, a person named Großmüller can now be written as GROẞMÜLLER in all-caps. Previously, writing it as GROSSMÜLLER left it unclear whether the original name was spelled with a ß or a double s.

Official Adoption and Usage

The capital ẞ isn’t just a typographic convenience; it’s an official rule. It became part of the official German orthography in 2017. While it remains a relatively rare character in everyday writing, it’s essential for maintaining precision in formal documents, legal texts, and high-impact visual design.

How to Type the Capital ẞ

Because the capital Eszett was added to the language relatively recently, it isn’t always the most intuitive key to find. On a standard PC keyboard, you can produce the character using the following key combination:

Alt Gr + Shift (Umschalt) + ß

Regional Exceptions: Switzerland and Liechtenstein

It’s crucial to note that the ß (and its capital counterpart ẞ) is not used everywhere German is spoken. In Switzerland and Liechtenstein, the Eszett is entirely absent from the writing system. In these countries, both the lowercase and uppercase versions are replaced by a double ss across the board.

Linguistic Curiosities: The Interrobang

The German language is full of rare symbols and evolving rules. Beyond the capital Eszett, linguists often point to the Interrobang (‽). This rare punctuation mark combines the question mark and the exclamation point into a single character, used to express a question asked with excitement or disbelief.

Key Takeaways

• Official Status: The capital ẞ became part of official German spelling in 2017.
• Primary Purpose: It prevents meaning confusion in all-caps text (e.g., distinguishing between dimensions and mass).
• Proper Names: It allows surnames to be written in all-caps without losing their original spelling.
• Regionality: It is not used in Switzerland or Liechtenstein, where ss is the standard.
• Shortcut: Type it using Alt Gr + Shift + ß.

FAQ

Can I still use “SS” instead of “ẞ”?

Yes, replacing ß with SS is still common, but using ẞ is more precise and prevents the ambiguity mentioned above.

Does the capital ẞ ever start a word?

No. Just like the lowercase ß, the capital version is only used within or at the end of a word.

Is the capital ẞ used in Swiss German?

No. Switzerland and Liechtenstein use ss exclusively.
