In [[German orthography]], the letter '''ß''', called '''{{lang|de|Eszett}}''' ({{IPA|de|ɛsˈtsɛt|IPA}}, S-Z) or '''{{lang|de|scharfes S}}''' ({{IPA|de|ˌʃaʁfəs ˈʔɛs|IPA}}, "sharp S"), represents the {{IPAslink|s}} phoneme in [[Standard German]] when following [[long vowel]]s and [[diphthong]]s. The letter-name {{wikt-lang|de|Eszett}} combines the [[names of the letters]] of {{angbr|s}} ({{lang|de|Es}}) and {{angbr|z}} ({{lang|de|Zett}}) in German. The character's [[Unicode]] names in English are '''double s''',<ref>{{cite web|url=https://www.lingoda.com/blog/en/german-double-s-eszett/|title=German double s and eszett|publisher=Lingoda|author=Sandra Köktas|date=20 September 2022 |language=English|accessdate=7 October 2024}}</ref> '''sharp s'''<ref name="Unicode_00DF">{{Citation |author=Unicode Consortium |author-link=Unicode Consortium |year=2018 |title=C1 Controls and Latin-1 Supplement, Range 0080–00FF |work=The Unicode Standard, Version 11.0 |url=https://www.unicode.org/charts/PDF/U0080.pdf |access-date=2018-08-09 |postscript=.}}</ref> and '''eszett'''.<ref name="Unicode_00DF" /> The ''Eszett'' letter is currently used only in [[German language|German]], and can be typographically replaced with the double-s digraph {{angbr|ss}} if the ß-character is unavailable.

The letter originated as the {{angbr|[[sz (digraph)|sz]]}} [[Digraph (orthography)|digraph]] used in [[Early New High German|late medieval and early modern German]] orthography, represented as a [[typographic ligature|ligature]] of {{angbr|ſ}} ([[long s]]) and {{angbr|ʒ}} ([[Z#Variant and derived forms|tailed z]]) in [[blackletter]] typefaces, yielding {{angbr|ſʒ}}.{{efn|The IPA symbol [[ezh]] (ʒ) somewhat resembles the Blackletter z (<math>\mathfrak{z}</math>) and is used in this article for convenience despite its technical inaccuracy. The preferred form of transcription by Unicode is the "hooked z" ([[ȥ]]), a toned-down version of the tailed z in 19th-century printed texts.}} This developed from an earlier usage of {{angbr|z}} in [[Old High German|Old]] and [[Middle High German]] to represent a [[sibilant]] that did not sound the same as {{angbr|s}}; when the difference between the two sounds was lost in the 13th century, the two symbols came to be combined as {{angbr|sz}} in some situations.

Traditionally, {{angbr|ß}} did not have a capital form, although some [[type design]]ers introduced ''de facto'' capitalized variants. In 2017, the [[Council for German Orthography]] officially adopted a capital, {{angbr|ẞ}}, as an acceptable variant in German orthography, ending a long orthographic debate.<ref name="Long debate">{{cite web|url=https://qz.com/1033265/germanys-century-long-debate-over-a-missing-letter-in-its-alphabet|title=Germany has ended a century-long debate over a missing letter in its alphabet|last=Ha|first=Thu-Huong|date=20 July 2017 |language=English|access-date=9 August 2017|quote=According to the council's 2017 spelling manual: When writing the uppercase [of ß], write SS.

Lowercase {{angbr|ß}} was [[codepoint|encoded]] by [[ECMA-94]] (1985) at position 223 (hexadecimal DF), inherited by [[Latin-1]] and [[Unicode]] ({{unichar|00DF|Latin small letter sharp s}}).<ref>[http://unicode.org/charts/PDF/U0080.pdf C1 Controls and Latin-1 Supplement] glossed 'uppercase is "SS" or 1E9E '''ẞ'''; typographically the glyph for this character can be based on a ligature of 017F '''ſ''', with either 0073 '''s''' or with an old-style glyph for 007A '''z''' (the latter similar in appearance to 0292 '''ʒ'''). Both forms exist interchangeably today.'</ref>
The [[List of XML and HTML character entity references|HTML entity]]  <code>&amp;szlig;</code> was introduced with [[HTML|HTML 2.0]] (1995). The capital {{angbr|ẞ}} was encoded by Unicode in 2008 at ({{unichar|1E9E|Latin Capital Letter Sharp S}}).

== Usage ==
===Current usage===
In [[standard German]], three letters or combinations of letters commonly represent {{IPA|de|s|}} (the [[voiceless alveolar fricative]]) depending on its position in a word: {{angbr|s}}, {{angbr|ss}}, and {{angbr|ß}}. According to [[German orthography reform of 1996|current German orthography]], {{angbr|ß}} represents the sound {{IPA|de|s|}}:
#when it is written after a [[diphthong]] or [[long vowel]] and is not followed by another consonant in the [[word stem]]: {{lang|de|Straße}}, {{lang|de|Maß}}, {{lang|de|groß}}, {{lang|de|heißen}} [Exceptions: {{lang|de|aus}} and words with [[final devoicing]] (e.g., {{lang|de|Haus}})];<ref name="IDS">{{cite web|title=Deutsche Rechtschreibung: 2.3 Besonderheiten bei [s] § 25 |url=https://grammis.ids-mannheim.de/rechtschreibung/6180 |access-date=28 January 2021}}</ref> and
#when a word stem ending with {{angbr|ß}} takes an [[inflection]]al ending beginning with a consonant: {{lang|de|heißt}}, {{lang|de|größte}}.<ref>{{cite book |title=Duden: Die Grammatik |edition=9 |year=2016 |page=84}}</ref>

In verbs with roots where the vowel changes length, this means that some forms may be written with {{angbr|ß}}, others with {{angbr|ss}}: {{lang|de|wissen}}, {{lang|de|er weiß}}, {{lang|de|er wusste}}.<ref name="IDS"/>

The use of {{angbr|ß}} distinguishes [[minimal pair]]s such as {{lang|de|reißen}} ({{IPA|de|ˈʁaɪsn̩|IPA}}, to rip) and {{lang|de|reisen}} ({{IPA|de|ˈʁaɪzn̩|IPA}}, to travel) on the one hand ({{IPA|de|s|}} vs. {{IPA|de|z|}}), and {{lang|de|Buße}} ({{IPA|de|ˈbuːsə|IPA}}, penance) and {{lang|de|Busse}} ({{IPA|de|ˈbʊsə|IPA}}, buses) on the other (long vowel before {{angbr|ß}}, short vowel before {{angbr|ss}}).<ref name="augst">{{cite book |author-last1=Augst |author-first1=Gerhard |author-last2=Stock |author-first2=Eberhard |chapter=Laut-Buchstaben-Zuordnung |title=Zur Neuregelung der deutschen Rechtschreibung: Begründung und Kritik |editor-last1=Augst |editor-first1=Gerhard |editor-last2=Blüml |editor-first2=Karl |display-editors=1 |publisher=Max Niemeyer |year=1997 |isbn=3-484-31179-7}}</ref>{{rp|123}}

Some proper names may use {{angbr|ß}} after a short vowel, following older orthography; this is also true of some words derived from proper names (e.g., {{lang|de|Litfaßsäule; [[advertising column]]}}, named after [[Ernst Litfaß]]).<ref name="poschenrieder">{{cite book|last=Poschenrieder |first=Thorwald |chapter=S-Schreibung - Überlieferung oder Reform? |title=Die Rechtschreibreform: Pro und Kontra |editor-last1=Eroms |editor-first1=Hans-Werner |editor-last2=Munske |editor-first2=Horst Haider|publisher=Erich Schmidt |year=1997 |isbn=3-50303786-1}}</ref>{{rp|180}}

If no {{angbr|ß}} is available in a font, then the official orthography calls for {{angbr|ß}} to be replaced with {{angbr|ss}}.<ref> {{cite web|access-date=20 September 2023 |url=https://grammis.ids-mannheim.de/rechtschreibung |title=Deutsche Rechtschreibung: Regeln und Wörterverzeichnis |at=2.3 E3 |quote={{lang|de|Steht der Buchstabe ß nicht zur Verfügung, so schreibt man ss.}} [If the letter ß is unavailable, then one writes ss.]}}</ref> Since 2024, when writing in capital letters {{angbr|ẞ}} has been preferred, but {{angbr|SS}} may be used instead.<ref name="Amtliches Regelwerk"/> Previously, {{angbr|SS}} was the preferred form.<ref name="DRR und W-2017">{{Cite web |access-date=29 June 2017 |url=http://www.rechtschreibrat.com/DOX/rfdr_Regeln_2017.pdf |title=Deutsche Rechtschreibung Regeln und Wörterverzeichnis: Aktualisierte Fassung des amtlichen Regelwerks entsprechend den Empfehlungen des Rats für deutsche Rechtschreibung 2016 |year=2017 |at=§25, E3 |quote={{lang|de|E3: Bei Schreibung mit Großbuchstaben schreibt man SS.

===In pre-1996 orthography===
[[File:RechtschreibreformBeiStrassennamen.jpg|thumb|Replacement street sign in [[Aachen]], adapted to the 1996 spelling reform (old: {{lang|de|Kongreßstraße}}, new: {{lang|de|Kongressstraße}})]]
According to the orthography in use in German prior to the [[German orthography reform of 1996]], {{angbr|ß}} was written to represent {{IPA|de|s|}}:
#word internally following a long vowel or diphthong: {{lang|de|Straße}}, {{lang|de|reißen}}; and
#at the end of a syllable or before a consonant, so long as {{IPA|de|s|}} is the end of the word stem: {{lang|de|muß}}, {{lang|de|faßt}}, {{lang|de|wäßrig}}.<ref name="poschenrieder"/>{{rp|176}}
In the old orthography, [[word stem]]s spelled {{angbr|ss}} internally could thus be written {{angbr|ß}} in certain instances, without this reflecting a change in vowel length: {{lang|de|küßt}} (from {{lang|de|küssen}}), {{lang|de|faßt}} (from {{lang|de|fassen}}), {{lang|de|verläßlich}} and {{lang|de|Verlaß}} (from {{lang|de|verlassen}}), {{lang|de|kraß}} (comparative: {{lang|de|krasser}}).<ref name="augst"/>{{rp|121-23}}<ref name="munske">{{cite book|last=Munske |first=Horst Haider|title=Lob der Rechtschreibung: Warum wir schreiben, wie wir schreiben |publisher=C. H. Beck |year=2005 |isbn=3-406-52861-9 |page=66}}</ref> In rare occasions, the difference between {{angbr|ß}} and {{angbr|ss}} could help differentiate words: {{lang|de|Paßende}} (expiration of a pass) and {{lang|de|passende}} (appropriate).<ref name="poschenrieder"/>{{rp|178}}

[[File:ABSCHUSZGERAET.jpg|thumb|Capitalization as SZ on a [[Bundeswehr]] crate ({{lang|de|ABSCHUSZGERAET}} for the pre-reform spelling {{lang|de|Abschußgerät}} 'launcher')]]
As in the new orthography, it was possible to write {{angbr|ss}} for {{angbr|ß}} if the character was not available. When using all capital letters, the pre-1996 rules called for rendering {{angbr|ß}} as {{angbr|SS}} except when there was ambiguity, in which case it should be rendered as {{angbr|SZ}}. The common example for such a case is {{lang|de|IN MASZEN}} ({{lang|de|in Maßen}} "in moderate amounts") vs. {{lang|de|IN MASSEN}} ({{lang|de|in Massen}} "in massive amounts"); in this example the spelling difference between {{angbr|ß}} vs. {{angbr|ss}} produces completely different meanings.{{cn|date=August 2023}}

=== Switzerland and Liechtenstein ===
In [[Swiss Standard German]], {{angbr|ss}} usually replaces every {{angbr|ß}}.<ref>{{ill|Peter Gallmann|de|lt=Peter Gallmann.}} [http://www.personal.uni-jena.de/~x1gape/Pub/Eszett_1997.pdf "Warum die Schweizer weiterhin kein Eszett schreiben."] in ''Die Neuregelung der deutschen Rechtschreibung.

As a result of the [[High German consonant shift]], [[Old High German]] developed a sound generally spelled {{angbr|zz}} or {{angbr|z}} that was probably pronounced {{IPA|[s]}} and was contrasted with a sound, probably pronounced {{IPA|[⁠s̠]}} ([[voiceless alveolar retracted sibilant]]) or {{IPA|[z̠]}} ([[voiced alveolar retracted sibilant]]), depending on the place in the word, and spelled {{angbr|s}}.<ref name="Salmons-2018">{{cite book |last=Salmons |first=Joseph |title=A History of German: What the past reveals about today's language |edition=2 |year=2018 |publisher=Oxford University Press |isbn=978-0-19-872302-8|page=203}}</ref> Given that {{angbr|z}} could also represent the [[affricate]] {{IPA|[ts]}}, some attempts were made to differentiate the sounds by spelling {{IPA|[s]}} as {{angbr|zss}} or {{angbr|zs}}: {{lang|goh|wazssar}} ({{langx|de|Wasser}}), {{lang|goh|fuozssi}} ({{langx|de|Füße}}), {{lang|goh|heizsit}} ({{langx|de|heißt}}).<ref>{{cite book|last=Braune |first=Wilhelm |title=Althochdeutsche Grammatik I |publisher=Max Niemeyer |year=2004 |isbn=3-484-10861-4 |page=152}}</ref> In [[Middle High German]], {{angbr|zz}} simplified to {{angbr|z}} at the end of a word or after a long vowel, but was retained word internally after a short vowel: {{lang|gmh|wazzer}} ({{langx|de|Wasser}}) vs. {{lang|gmh|lâzen}} ({{langx|de|lassen}}) and {{lang|mhg|fuoz}} ({{langx|de|Fuß}}).<ref name="Paul-1998">{{cite book |last=Paul |first=Hermann |title=Mittelhochdeutsche Grammatik |edition=24 |year=1998 |publisher=Max Niemeyer |isbn=3-484-10233-0 |page=163 }}</ref>

By the late 1400s, the choice of spelling between {{angbr|sz}} and {{angbr|ss}} was usually based on the sound's position in the word rather than etymology: {{angbr|sz}} ({{angbr|ſz}}) tended to be used in word final position: {{lang|de|uſz}} ({{langx|gmh|ûz}}, {{langx|de|aus}}), {{lang|de|-nüſz}} ({{langx|gmh|-nüss(e)}}, {{langx|de|-nis}}); {{angbr|ss}} ({{angbr|ſſ}}) tended to be used when the sound occurred between vowels: {{lang|de|groſſes}} ({{langx|gmh|grôzes}}, {{langx|de|großes}}).<ref name="young">{{cite book |last1=Young |first1=Christopher |last2=Gloning |first2=Thomas |title=A History of the German Language Through Texts |publisher=Routledge |year=2004 |isbn=978-0-415-86263-9}}</ref>{{rp|171}} While [[Martin Luther]]'s early 16th-century printings also contain spellings such as {{lang|de|heyße}} ({{langx|de|heiße}}), early modern printers mostly changed these to {{angbr|ſſ}}: {{lang|de|heiſſe}}. Around the same time, printers began to systematically distinguish between {{lang|de|das}} (the, that [pronoun]) and {{lang|de|daß}} (that [conjunction]).<ref name="young"/>{{rp|215}}

In modern German, the Old and Middle High German {{angbr|z}} is now represented by either {{angbr|ss}}, {{angbr|ß}}, or, if there are no related forms in which {{IPA|[s]}} occurs intervocalically, with {{angbr|s}}: {{lang|de|messen}} ({{langx|gmh|mezzen}}), {{lang|de|Straße}} ({{langx|gmh|strâze}}), and {{lang|de|was}} ({{langx|gmh|waz}}).<ref name="Paul-1998"/>

=== Standardization of use ===
The pre-1996 German use of {{angbr|ß}} was codified by the eighteenth-century grammarians [[Johann Christoph Gottsched]] (1748) and [[Johann Christoph Adelung]] (1793) and made official for all German-speaking countries by the [[German Orthographic Conference of 1901]]. In this orthography, the use of {{angbr|ß}} was modeled after the use of [[long s|long]] and "round"-s in Fraktur. {{angbr|ß}} appeared both word internally after long vowels and also in those positions where Fraktur required the second s to be a "round" or "final" s, namely the ends of syllables or the ends of words.<ref name="walder"/>{{rp|217-18}} In his ''[[Deutsches Wörterbuch]]'' (1854) [[Jacob Grimm]] called for {{angbr|ß}} or {{angbr|sz}} to be written for all instances of Middle and Old High German etymological {{angbr|z}} (e.g., {{lang|de|eß}} instead of {{lang|de|es}} from {{langx|gmh|ez}}); however, his etymological proposal could not overcome established usage.<ref name="young"/>{{rp|269}}

In [[Austria-Hungary]] prior to the German Orthographic Conference of 1902, an alternative rule formulated by  [[Johann Christian August Heyse]] in 1829 had been officially taught in the schools since 1879, although this spelling was not widely used. Heyse's rule matches current usage after the [[German orthography reform of 1996]] in that {{angbr|ß}} was only used after long vowels.<ref name="walder"/>{{rp|219}}

===Use in Roman type===

In early modern Latin type ([[antiqua (typeface class)|antiqua]]), a ligature similar to modern {{angbr|ß}} developed out of a long s followed by a round s ({{angbr|ſs}}), and as such was used in languages such as Italian in alternation with {{angbr|ſſ}}, usually based on requirements of space on the page.<ref>{{cite book|author-last=Michel |author-first=Andreas |chapter=Italian orthography in Early Modern times |title=Orthographies in Early Modern Europe |editor-last1=Baddeley |editor-first1=Susan |editor-last2=Voeste |editor-first2=Anja |year=2012 |publisher=de Gruyter Mouton |doi=10.1515/9783110288179.63 |pages=63–96|isbn=978-3-11-028817-9 }}</ref>{{rp|76}} However, despite its resemblance to the modern {{angbr|ß}}, this ligature was not commonly used as an equivalent to the Fraktur {{angbr|sz}} in German.<ref name="mosley">{{citation|last=Mosley|first=James|date=2008-01-31|title=Esszet or ß|website=Typefoundry|url=https://typefoundry.blogspot.com/2008/01/esszett-or.html|access-date=2019-05-05}}</ref><ref name="jamra">{{citation|last=Jamra|first=Mark|year=2006|title=The Eszett| website=TypeCulture|url=https://typeculture.com/academic-resource/articles-essays/the-eszett/|access-date=2019-05-05}}</ref> This ligature generally fell out of use in the eighteenth century, together with the use of long s in antiqua.<ref name="brekle"/>{{rp|73}} German works printed in Roman type in the late 18th and early 19th centuries such as [[Johann Gottlieb Fichte]]'s {{lang|de|Wissenschaftslehre}} did not provide any equivalent to the {{angbr|ß}}.<ref name="brekle"/>{{rp|74}}

Until the abolition of Fraktur in 1941, it was common for [[family name]]s to be written with {{angbr|ß}} in Fraktur and {{angbr|ss}} in Roman type. The formal abolition resulted in inconsistencies in how names are written in modern German (such as between Heuss and Heuß).<ref name="poschenrieder"/>{{rp|176}}

===Abolition and attempted abolitions===
The Swiss and Liechtensteiners ceased to use {{angbr|ß}} in the twentieth century. This has been explained variously by the early adoption of Roman type in Switzerland, the use of [[typewriter]]s in Switzerland that omitted {{angbr|ß}} in favor of French and Italian characters, and peculiarities of [[Swiss German]] that cause words spelled with {{angbr|ß}} or {{angbr|ss}} to be pronounced with [[gemination]].<ref name="walder"/>{{rp|221-22}} The Education Council of [[Zürich]] had decided to stop teaching the letter in 1935, whereas the [[Neue Zürcher Zeitung]] continued to write {{angbr|ß}} until 1971.<ref>{{cite book| last=Ammon |first=Ulrich |year=1995 |title=Die deutsche Sprache in Deutschland, Österreich und der Schweiz: das Problem der nationalen Varietäten |publisher=de Gruyter |isbn=9783110147537 |page=254}}</ref> Swiss newspapers continued to print in Fraktur until the end of the 1940s, and the abandonment of ß by most newspapers corresponded to them switching to Roman typesetting.<ref>{{cite book| last=Gallmann |first=Paul |chapter=Warum die Schweizer weiterhin kein Eszett schreiben |title=Die Neuregelung der deutschenRechtschreibung.

When the Nazi German government abolished the use of blackletter typesetting in 1941, it was originally planned to also abolish the use of {{angbr|ß}}. However, Hitler intervened to retain {{angbr|ß}}, while deciding against the creation of a capital form.<ref>Schreiben des Reichsministers und Chefs der Reichskanzlei an den Reichsminister des Innern vom 20.

===Development of a capital form <span class="anchor" id="Capital form"></span>===
[[File:Eszett Leipziger Duden 1957.png|thumb|Uppercase ß on a book cover from 1957]]
[[File:Gießener Zeitung Logo.svg|class=skin-invert-image|thumb|Logo of {{Interlanguage link|Gießener Zeitung|lt=''Gießener Zeitung''|de}} ("{{lang|de|GIEẞENER ZEITUNG}}", 2008 design)]]

Because {{angbr|ß}} had been treated as a ligature, rather than as a full letter of the German alphabet, it had no capital form in early modern typesetting. Moreover, [[allcaps]] was not normally used in Fraktur printing.<ref name="Long debate" /> There were, however, proposals to introduce capital forms of {{angbr|ß}} for use in allcaps writing (where {{angbr|ß}} would otherwise usually be represented as either {{angbr|SS}} or {{angbr|SZ}}). A capital was first seriously proposed in 1879, but did not enter official or widespread use.<ref>{{lang|de|Signa – Beiträge zur Signographie}}. Heft 9, 2006.</ref> The Orthographic Conference of 1903 called for the use of {{angbr|SZ}} in allcaps until a capital letter could be proposed.<ref name="Long debate" /> Historical typefaces offering a capitalized {{lang|de|eszett}} mostly date to the time between 1905 and 1930. The first known typefaces to include capital {{lang|de|eszett}} were produced by the {{lang|de|Schelter & Giesecke}} foundry in Leipzig, in 1905/06. {{lang|de|Schelter & Giesecke}} at the time widely advocated the use of this type, but its use nevertheless remained very limited.

The preface to the 1925 edition of the {{lang|de|[[Duden]]}} dictionary expressed the desirability of a separate glyph for capital {{angbr|ß}}:
{{quote|{{lang|de|Die Verwendung zweier Buchstaben für einen Laut ist nur ein Notbehelf, der aufhören muss, sobald ein geeigneter Druckbuchstabe für das große ß geschaffen ist.}}<ref>{{lang|de|Vorbemerkungen, XII.}} In: {{lang|de|Duden – Rechtschreibung. 9. Auflage, 1925}}</ref>}}
{{quote|The use of two letters for a single phoneme is makeshift, to be abandoned as soon as a suitable type for the capital ß has been developed.}}

The {{lang|de|Duden}} was edited separately in [[East Germany|East]] and [[West Germany]] during the 1950s to 1980s. The East German {{lang|de|Duden}} of 1957 (15th ed.) introduced a capital {{angbr|ß}} in its typesetting without revising the rule for capitalization. The 16th edition of 1969 still announced that an uppercase {{angbr|ß}} was in development and would be introduced in the future. The 1984 edition again removed this announcement and simply stated that there is no capital version of {{angbr|ß}}.<ref>{{lang|de|Der Große Duden. 25. Auflage, Leipzig 1984, S. 601, K 41.}}</ref>

In the 2000s, there were renewed efforts on the part of certain [[typographer]]s to introduce a capital, {{angbr|ẞ}}. A proposal to include a corresponding character in the [[Unicode]] set submitted in 2004<ref>{{cite web |url=http://std.dkuug.dk/jtc1/sc2/wg2/docs/n2888.pdf |author=Andreas Stötzner |title=Proposal to encode Latin Capital Letter Double S (rejected) |access-date=2021-06-25 }}</ref> was rejected.<ref>{{cite web |url=https://www.unicode.org/L2/L2004/04361.htm#101-C22 |title=Approved Minutes of the UTC 101 / L2 198 Joint Meeting, Cupertino, CA – November 15-18, 2004 |author=<!--Not stated--> |date=2005-02-10 |publisher=[[Unicode Consortium]] |access-date=2021-06-25 |quote=The UTC concurs with Stoetzner that Capital Double S is a typographical issue.

== Representation ==
===Graphical variants===
The recommendation of the [[Sulzbacher form]] (1903) was not followed universally in 20th-century printing. There were four distinct variants of {{angbr|ß}} in use in Antiqua fonts:
[[File:Sz modern.svg|class=skin-invert-image|thumb|Four forms of Antiqua Eszett: 1. ſs, 2. ſs ligature, 3. ſʒ ligature, 4. Sulzbacher form]]
#{{angbr|ſs}} without ligature, but as a single type, with reduced spacing between the two letters;
#the ligature of {{angbr|ſ}} and {{angbr|s}} inherited from the 16th-century Antiqua typefaces;
#a ligature of {{angbr|ſ}} and {{angbr|ʒ}}, adapting the blackletter ligature to Antiqua; and
#the Sulzbacher form.

The first variant (no ligature) has become practically obsolete. Most modern typefaces follow either 2 or 4, with 3 retained in occasional usage, notably in street signs in Bonn and Berlin. The design of modern {{angbr|ß}} tends to follow either the Sulzbacher form, in which {{angbr|ʒ}} (tailed z) is clearly visible, or else be made up of a clear ligature of {{angbr|ſ}} and {{angbr|s}}.<ref name="jamra"/>{{rp|2}}

The inclusion of a capital {{angbr|ẞ}} in [[Unicode]] in 2008 revived the century-old debate among [[type design|typeface designers]] as to how such a character should be represented. The main difference in the shapes of {{angbr|ẞ}} in contemporary typefaces is the depiction with a diagonal straight line vs. a curved line in its upper right part, reminiscent of the ligature of [[Ezh|tailed z]] or of [[s|round s]], respectively. The code chart published by the Unicode Consortium favours the former possibility,<ref>{{Cite web|url=http://unicode.org/charts/PDF/U1E00.pdf|title=Latin Extended Additional}}</ref> which has been adopted by Unicode capable fonts including [[Arial]], [[Calibri]], [[Cambria (typeface)|Cambria]], [[Courier New]], [[DejaVu fonts|Dejavu Serif]], [[Liberation Sans]], [[Liberation Mono]], [[Linux Libertine]] and [[Times New Roman]]; the second possibility is more rare, adopted by [[DejaVu fonts|Dejavu Sans]]. Some fonts adopt a third possibility in representing {{angbr|ẞ}} following the Sulzbacher form of {{angbr|ß}}, reminiscent of the Greek {{angbr|[[β]]}} (beta); such a shape has been adopted by [[FreeSans]] and [[FreeSerif]], [[Liberation Serif]] and [[Verdana]].<ref>{{Cite web|url=https://www.fileformat.info/info/unicode/char/1e9e/fontsupport.htm|title=Latin Capital Letter Sharp S (U+1E9E) Font Support|website=fileformat.info}}</ref>
