The Long S

Bill of Rights Day is December 15. Visit the National Archives website for more information. Today’s post comes from Rachel Bartgis, conservator technician at the National Archives at College Park, MD.

One of the most frequent questions visitors to the National Archives Rotunda have about the Bill of Rights is why is the word Congress in the heading has an “f” in it.

The “f” in question is not actually an f but a separate character now called the “long s.” A close comparison of the two letters shows that they differ slightly. In printed type, the cross-bar of the lowercase f goes all the way through, but the cross-bar on the long s is only on the left side of the letter’s “stem” (the vertical line forming the body of the letter).

In cursive handwriting, the bottom curve of the long s goes to the left, while in the f, it goes to the right or doesn’t exist.

While the rules changed over time and from language to language (and weren’t always followed by the writer or printer), the basic guidelines for when the long s was used in 18th- and early 19th-century English-language documents were:

  • It only applied to lowercase s, not uppercase S.
  • If an s was at the beginning or in the middle of a word, the long s was used (ſurpriſe for suprise).
  • If a word included ss, a double long s was used unless the letters were at the end of a word; otherwise it was finished with a regular s, as in poſſeſs (possess), not poſſeſſ (a relative of the German letter ß, or eszett).
  • The long s was not used when s was the last letter of the word. 

There’s no clear answer for why the long s exists as a typographical feature of the Roman alphabet, though the Cyrillic and Greek alphabets also distinguish between different forms of s, such as σ and ς as the two forms of the Greek letter sigma.

The shift away from using the long s in English took almost a century, from the mid-18th century to the early 19th. It began when people began abandoning the long s in “roundhand,” the neat, clear cursive handwriting favored by businesses for keeping accounts and writing official documents—the exception being the double s at the end of a word. This draft of the Constitution shows the process clearly:

This entirely handwritten act of Congress from 1794 is another good example, with the long s missing unless it’s a part of the double s (ſs) that appears in Congress.

Meanwhile, it took several more decades before printers stopped using the long s in type due to the need to cast new type and redesign the cases that held printer’s type. No longer using the long s didn’t mean abandoning just one piece of type since 18th-century typefaces consist of a variety of ligatures, or combinations of letters joined in a single piece of metal type, such as  ſh, ſt, and ſs.

The long s stopped being used in printed materials in England during the 1810s and 1820s, while it died out a little earlier in the United States. It occasionally persisted in English handwriting (particularly the use of ſs for a final ss) and in the published copy books that taught handwriting through the 1870s, and the sharp-eyed researcher can find examples of ſs in the occasional Civil War–era record.

  1. Hello. I’m from Japan. Thank you very much for giving valuable information about “Long s”.
    I read King James Version Holy Bible published in 1611 the other day and I found “Long s” in the sentences. I want to know the history of the usage of “Long s”.
    I’m looking for some books written about the letter and I happened to find your article today.
    I want to know where you found the information; The long s stopped being used in printed materials in England during the 1810s and 1820s.
    If you remember how you got this information, may I know that?
    Thank you for reading my message.

    1. It’s funny, I got to this site because I was asking chatGPT about the japanese kanji ゐ and ゑ. I asked if there were english characters that fell out of usage in similar manner, and was told about the long s in english. It is quite a coincidence that the first article I found and the first comment I saw was someone from japan!
      Languages are cool aren’t they?

    2. The long s did not stop being used in England the early 19th century in handwriting, it went on much longer than that. The article says its use was perpetuated in books that taught handwriting through the 1870s and I can confirm that. My great grandfather who was born in 1865 and died in 1948 always used the long s. He was not uneducated either, he went to boarding school and he must have been taught to write using the long s.

  2. Hello,
    The long s fell out of use in the English language in the 19th century due to changes in printing technology and typography. The long s, which was used at the beginning and in the middle of words, was often confused with the letter f, which led to its gradual replacement with the short s. Additionally, the development of new typefaces and type design, such as the introduction of the sans-serif font, also contributed to the decline of the long s.
