The long s, , also known as the '''medial ''s'' or initial ''s''''', is an archaic form of the lowercase letter , 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 (e.g., "ſinfulneſs" for "sinfulness" and "poſſeſs" or "poſseſs" for "possess", but never "poſſeſſ"). The modern 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 , ( or , 'sharp ''s'''). As with other letters, the long ''s'' may have a variant appearance depending on typeface: ſ, ſ, ſ, ſ. Provided by Wikipedia
