German alphabet
The modern German alphabet consists of the twenty-six letters of the ISO basic Latin alphabet plus four extra letters placed at the end: German uses letter-diacritic combinations (Ä/ä, Ö/ö, Ü/ü) using the umlaut and one ligature (ẞ/ß (called eszett (sz) or scharfes S, sharp s)). Before 1940 German employed Fraktur, a blackletter typeface (see also Antiqua–Fraktur dispute), and Kurrent, various cursives that include the 20-century Sütterlin.
