Long s

Archaic form of the Latin-script letter s (ſ)

The long s, ⟨ſ⟩, also known as the medial s or initial s, is an archaic form of the lowercase letter ⟨s⟩, found mostly in works from the late 8th to early 19th centuries. It replaced the single s, or one or both of the letters s in a double-s sequence. The modern ⟨s⟩ letterform is known as the "short", "terminal", or "round" s. In typography, the long s is known as a type of swash letter, commonly referred to as a "swash s". The long s is the basis of the first half of the grapheme of the German alphabet ligature letter ⟨ß⟩,. As with other letters, the long s may have a variant appearance depending on typeface: ſ, ſ, ſ, ſ.
