History

, and often for a practical reason: faster handwriting. Merchants especially needed a way to speed up the process of written communication and found that conjoining letters and abbreviating words for lay use was more convenient for record keeping and transaction than the bulky long forms. Around the 9th and 10th centuries, monasteries became a fountainhead for these types of script modifications. Medieval scribes who wrote in

, letters with right-facing bowls (, , and ) and those with left-facing bowls (, , , , and ) were written with the facing edges of the bowls superimposed. In many script forms, characters such as , , and had their vertical strokes superimposed. Scribes also used notational abbreviations to avoid having to write a whole character in one stroke. Manuscripts in the fourteenth century employed hundreds of such abbreviations. In handwriting, a ligature is made by joining two or more characters in an atypical fashion by merging their parts, or by writing one above or inside the other. In printing, a ligature is a group of characters that is typeset as a unit, so the characters do not have to be joined. For example, in some cases the ligature prints the letters and with a greater separation than when they are typeset as separate letters. When printing with movable type was invented around 1450, typefaces included many ligatures and additional letters, as they were based on handwriting. Ligatures made printing with movable type easier because one sort would replace frequent combinations of letters and also allowed more complex and interesting character designs which would otherwise collide with one another. Because of their complexity, ligatures began to fall out of use in the 20th century. Sans serif typefaces, increasingly used for body text, generally avoid ligatures, though notable exceptions include Gill Sans and Futura. Inexpensive

revolution. Early computer software in particular had no way to allow for ligature substitution (the automatic use of ligatures where appropriate), while most new digital typefaces did not include ligatures. As most of the early PC development was designed for the English language (which already treated ligatures as optional at best) dependence on ligatures did not carry over to digital. Ligature use fell as the number of traditional hand compositors and hot metal typesetting machine operators dropped because of the mass production of the IBM Selectric brand of electric typewriter in 1961. A designer active in the period commented: "some of the world's greatest typefaces were quickly becoming some of the world's worst fonts." Ligatures have grown in popularity in the 21st century because of an increasing interest in creating typesetting systems that evoke arcane designs and classical scripts. One of the first computer typesetting programs to take advantage of computer-driven typesetting (and later laser printers) was Donald Knuth's

A parallel use of ligatures is seen in the creation of script fonts that join letterforms to simulate handwriting effectively. This trend is caused in part by the increased support for other languages and alphabets in modern computing, many of which use ligatures somewhat extensively. This has caused the development of new digital typesetting techniques such as OpenType, and the incorporation of ligature support into the text display systems of

Today, modern font programming divides ligatures into three groups, which can be activated separately: standard, contextual and historical. Standard ligatures are needed to allow the font to display without errors such as character collision. Designers sometimes find contextual and historic ligatures desirable for creating effects or to evoke an old-fashioned print look.

Stylistic ligatures

Many ligatures combine with the following letter. A particularly prominent example is (or , rendered with two normal letters). The tittle of the in many typefaces collides with the hood of the when placed beside each other in a word, and are combined into a single glyph with the tittle absorbed into the .

). Besides conventional ligatures, in the metal type era some newspapers commissioned custom condensed single sorts for the names of common long names that might appear in news headings, such as " Eisenhower", " Chamberlain". In these cases the characters did not appear combined, just more tightly spaced than if printed conventionally.


German ß

The German letter (, also called the , meaning ''sharp s'') is an official letter of the alphabet in Germany and Austria. A recognizable ligature representing the digraph develops in handwriting in the early 14th century. Its name (meaning S-Z) suggests a connection of "long s and z" (ſʒ) but the Latin script also knows a ligature of "long s over round s" (ſs). Since German was mostly set in blackletter typefaces until the 1940s, and those typefaces were rarely set in uppercase, a capital version of the never came into common use, even though its creation has been discussed since the end of the 19th century. Therefore, the common replacement in uppercase typesetting was originally SZ ( "measure" → , different from "mass" → ) and later SS ( → ). Until 2017, the SS replacement was the only valid spelling according to the official orthography in Germany and Austria. In Switzerland, the ß is omitted altogether in favour of ss. The capital version (ẞ) of the Eszett character was occasionally used since 1905/06, has been part of Unicode since 2008, and has appeared in more and more typefaces. Since the end of 2010, the has suggested the new upper case character for "ß" rather than replacing it with "SS" or "SZ" for geographical names. A new standardized German keyboard layout (DIN 2137-T2) has included the capital ß since 2012. The new character entered the official orthographic rules in June 2017.


Massachusett ꝏ

A prominent feature of the colonial orthography created by John Eliot (later used in the first Bible printed in the Americas, the Massachusett-language , published in 1663) was the use of the double-o ligature to represent the of ''food'' as opposed to the of ''hook'' (although Eliot himself used and interchangeably). In the orthography in use since 2000 in the Wampanoag communities participating in the Wôpanâak Language Reclamation Project (WLRP), the ligature was replaced with the numeral , partly because of its ease in typesetting and display as well as its similarity to the o-u ligature used in Abenaki. For example, compare the colonial-era spelling with the modern Wôpanâak Language Reclamation Project (WLRP) spelling .

Digraphs

Digraphs, such as in Spanish or Welsh, are not ligatures in the general case as the two letters are displayed as separate glyphs: although written together, when they are joined in handwriting or italic fonts the base form of the letters is not changed and the individual glyphs remain separate. Like some ligatures discussed above, these digraphs may or may not be considered individual letters in their respective languages. Until the 1994 spelling reform, the digraphs and were considered separate letters in Spanish for collation purposes. Catalan makes a difference between "Spanish ll" or palatalized l, written as in (law), and "French ll" or geminated l, written as in (colleague). The difference can be illustrated with the French digraph , which is composed of the ligature and the simplex letter .

However, in the 19th century these were often written via compound characters, pronounced disyllabically, such as for or for – some of these characters were also used in Japan, where they were pronounced with borrowed European readings instead. These have now fallen out of general use, but are occasionally seen.Victor Mair

s to a single character, used for ligature substitution. Typesetting software may or may not implement this feature, even if it is explicitly present in the font's metadata. XeTeX is a TeX typesetting engine designed to make the most of such advanced features. This type of substitution used to be needed mainly for typesetting Arabic texts, but ligature lookups and substitutions are being put into all kinds of Western Latin OpenType fonts. In OpenType, there are standard liga, historical hlig, contextual clig, discretionary dlig and required rlig ligatures.


TeX

Opinion is divided over whether it is the job of writers or typesetters to decide where to use ligatures.
TeX Tex, TeX, TEX, may refer to: People and fictional characters * Tex (nickname), a list of people and fictional characters with the nickname * Tex Earnhardt (1930–2020), U.S. businessman * Joe Tex (1933–1982), stage name of American soul singer ...

When TeX finds these combinations in a text, it substitutes the appropriate ligature, unless overridden by the typesetter.


CSS

CSS3 provides control over these properties using font-feature-settings, though the CSS Fonts Module Level 4 draft standard indicates that authors should prefer several other properties. Those include font-variant-ligatures, common-ligatures, discretionary-ligatures, historical-ligatures, and contextual.

maintains that ligaturing is a presentation issue rather than a character definition issue, and that, for example, "if a modern font is asked to display 'h' followed by 'r', and the font has an 'hr' ligature in it, it can display the ligature." Accordingly, the use of the special Unicode ligature characters is "discouraged", and "no more will be encoded in any circumstances".
