Final Form

In certain languages, the final form or terminal form is a special character used to represent a letter only when it occurs at the end of a word. Some languages that use final form characters are: Arabic, Hebrew, Manchu and one letter in Greek (ς). The lowercase Latin letter "s" had separate medial (ſ) and final (s) in the orthographies of many European languages from the medieval period to the early 19th century; it survived in the German Fraktur script until the 1940s.
