These letters, according to the emperor, were much needed for the language, although they did not outlast his reign.

==<span class="anchor" id="Antisigma"></span>{{lang|la|Antisigma}} (Ↄ) == {{redirect-distinguish-text|Ↄ|the Latin letter [[Open O]] (Ɔ) or the Greek letter [[reversed lunate sigma]] (Ͻ)}} '''Ↄ''' or '''[[File:Claudian antisigma.svg|15x15 px|class=skin-invert-image]]/X''' ({{lang|la|antisigma}}) to replace BS {{IPA|la|bz|}} and PS {{IPA|la|ps|}}, much as [[X]] stood in for CS {{IPA|la|ks|}} and GS {{IPA|la|ɡz|}}. The shape of this letter is disputed, however, since no inscription bearing it has been found. [[Franz Bücheler]] identified it with the variant [[Roman numerals|Roman numeral]] Ↄ,<ref name="Bücheler">[[Franz Bücheler|Bücheler, Franz]]: {{Google books|id=lSg9AAAAcAAJ|title=De Ti. Claudio Caesare Grammatico}} (Latin), Elberfeld (Germany) 1856</ref> but 20th-century philologists, working from copies of [[Priscian]]'s books, believe it to instead resemble two linked Cs (Ↄ+Ϲ), which was a preexisting variant of Greek [[sigma]], and easily mistaken for X by later writers. [[Revilo P. Oliver]] argued that Claudius would have based this letter upon the Arcadian variant of [[Psi (letter)|psi]] {{GrGl|Psi 01}} or {{GrGl|Psi X-shaped}}.<ref name="oliver">{{cite journal |last=Oliver |first=Revilo P. |year=1949 |title=The Claudian Letter Ⱶ |journal=American Journal of Archaeology |volume=53 |issue= 3|pages=249–257 |doi=10.2307/500662 |jstor= 500662|s2cid=193082268 }}</ref>

As noted, no examples of this letter from the time have been discovered; its usage must be guessed at. It would probably replace the PS or BS sequence in Latin words, especially those with Greek etymology, such as {{lang|la-x-classic|DYSPEↃIA}} ({{lang|la|dyspepsia}}), {{lang|la-x-classic|EPILEↃIA}} ({{lang|la|epilepsia}}), {{lang|la-x-classic|ↃALMVS}} ({{lang|la|psalmus}}), or {{lang|la-x-classic|VRↃ}} ({{lang|la|urbs}}).

It was used before [[labial consonant]]s in Latin words such as {{lang|la|optumus}} and {{lang|la|optimus}}. The letter was later used as a variant of {{IPAblink|y}} in inscriptions for short Greek [[upsilon]] (as in {{lang|la|Olympicus}}).

==Usage== These letters were used to a small extent on public inscriptions dating from Claudius' reign, but their use was abandoned after his death.<ref>[[Tacitus]], ''[[Annals (Tacitus)|Annals]]'' 11[10]:14</ref> Their forms were probably chosen to ease the transition, as they could be made from templates for existing letters. He may have been inspired by his ancestor [[Appius Claudius Caecus|Appius Claudius]] the [[Roman censor|Censor]], who made earlier changes to the Latin alphabet.<ref>{{cite journal |last=Ryan |first=F. X. |year=1993 |title=Some Observations on the Censorship of Claudius and Vitellius, A.D. 47–48 |journal=American Journal of Philology |volume=114 |issue=4 |pages=611–618 |doi=10.2307/295428 |jstor= 295428}}</ref> Claudius did indeed introduce his letters during his own term as censor (47–48), using arguments preserved in the historian [[Tacitus]]' account of his reign, although the original proclamation is no longer extant. [[Suetonius]] said of Claudius' letters:

{{quote|Besides this he [Claudius] invented three new letters and added them to the alphabet, maintaining that they were greatly needed; he published a book on their theory when he was still in private life, and when he became emperor had no difficulty in bringing about their general use. These characters may still be seen in numerous books, in the [state] registers, and in inscriptions on public buildings.<ref>[https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Suetonius/12Caesars/Claudius*.html Suetonius pass], Loeb Classical Library edition, 1913‑1914, English translation is by J. C. Rolfe. [https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Suetonius/12Caesars/Claudius*.html#p75 Page 77, paragraph 41]. (From [[LacusCurtius]])</ref>}}

Assuming that the letters were added at the end of the alphabet, just like [[Y]] and [[Z]] were, and that the order of these 3 letters does not matter, the Latin alphabet with these letters would look like this:

{| class="wikitable" style="text-align:center" |+ Classical Latin alphabet with the additional Claudian letters |- ! style="text-align:left" | Letter ! [[A]] !! [[B]] !! [[C]] !! [[D]] !! [[E]] !!

Support for the letters was added in version 5.0.0 of [[Unicode]].<ref name="L2-05-193R2">{{cite web|url=https://www.unicode.org/L2/L2005/05193r2-n2960r2-claudian.pdf|title=Proposal to add Claudian Latin letters to the UCS|date=2005-08-12|work=Unicode Technical Committee, Document L2/05-193R2 = ISO/IEC JTC1/SC2/WG2, Document N2960R2 |access-date=2021-12-27|author=[[Michael Everson]]}}</ref> Although these letters, as all Latin letters in antiquity, originally occurred only in capital form, lowercase forms were introduced to meet Unicode casing requirements.<ref name="L2-05-193R2"/> The minuscule form for the turned F was designed as a turned small capital F and should not be confused with the [[International Phonetic Alphabet|IPA]] symbol {{IPA link|ɟ||[}} representing a voiced palatal stop.
