A cedilla (// si-DIL-ə; from Spanish), also known as cedilha (from Portuguese) or cédille (from French), is a hook or tail ( ¸ ) added under certain letters as a diacritical mark to modify their pronunciation. In Catalan, French, and Portuguese, it is used only under the c, and the entire letter is called respectively c trencada (i.e. "broken C"), c cédille, and c cedilhado (or c cedilha, colloquially).
The tail originated in Spain as the bottom half of a miniature cursive z. The word "cedilla" is the diminutive of the Old Spanish name for this letter, ceda (zeta). Modern Spanish and Galician no longer use this diacritic, although it is used in Portuguese, Catalan, Occitan, and French, which gives English the alternative spellings of cedille, from French "cédille", and the Portuguese form cedilha. An obsolete spelling of cedilla is cerilla. The earliest use in English cited by the Oxford English Dictionary is a 1599 Spanish-English dictionary and grammar. Chambers’ Cyclopædia is cited for the printer-trade variant ceceril in use in 1738. The main use in English is not universal and applies to loan words from French and Portuguese such as "façade", "limaçon" and "cachaça" (often typed "facade", "limacon" and "cachaca" because of lack of ç keys on Anglophone keyboards).
With the advent of modernism, the calligraphic nature of the cedilla was thought somewhat jarring on sans-serif typefaces, and so some designers instead substituted a comma design, which could be made bolder and more compatible with the style of the text. This can add to confusion as the use of commas as opposed to cedillas varies by language.
The most frequent character with cedilla is "ç" ("c" with cedilla, as in façade). It was first used for the sound of the voiceless alveolar affricate /ts/ in old Spanish and stems from the Visigothic form of the letter "z" (ꝣ), whose upper loop was lengthened and reinterpreted as a "c", whereas its lower loop became the diminished appendage, the cedilla.
It represents the "soft" sound /s/, the voiceless alveolar sibilant, where a "c" would normally represent the "hard" sound /k/ (before "a", "o", "u", or at the end of a word) in English and in certain Romance languages such as Catalan, Galician, French (where ç appears in the name of the language itself, français), Ligurian, Occitan, and Portuguese. In Occitan, Friulian and Catalan ç can also be found at the beginning of a word (Çubran, ço) or at the end (braç).
It represents the voiceless postalveolar affricate /tʃ/ (as in English "church") in Albanian, Azerbaijani, Crimean Tatar, Friulian, Kurdish, Tatar, Turkish (as in çiçek, çam, çekirdek, Çorum), and Turkmen. It is also sometimes used this way in Manx, to distinguish it from the velar fricative.
The character "ş" represents the voiceless postalveolar fricative /ʃ/ (as in "show") in several languages, including many belonging to the Turkic languages, and included as a separate letter in their alphabets:
- Crimean Tatar
- Romanian (substitution use when S-comma [Ș] was missing from pre-3.0 Unicode standards, and older standards, still frequent, but an error)
- In HTML character entity references
şcan be used.
Comparatively, some consider the diacritics on the palatalized Latvian consonants "ģ", "ķ", "ļ", "ņ", and formerly "ŗ" to be cedillas. Although their Adobe glyph names are commas, their names in the Unicode Standard are "g", "k", "l", "n", and "r" with a cedilla. The letters were introduced to the Unicode standard before 1992, and their names cannot be altered. The uppercase equivalent "Ģ" sometimes has a regular cedilla.
Four letters in Marshallese have cedillas: <ļ m̧ ņ o̧>. In standard printed text they are always cedillas, and their omission or the substitution of comma below and dot below diacritics are nonstandard.
As of 2011, many font rendering engines do not display any of these properly, for two reasons:
- "ļ" and "ņ" usually do not display properly at all, because of the use of the cedilla in Latvian. Unicode has precombined glyphs for these letters, but most quality fonts display them with comma below diacritics to accommodate the expectations of Latvian orthography. This is considered nonstandard in Marshallese. The use of a zero-width non-joiner between the letter and the diacritic can alleviate this problem: "ļ" and "ņ" may display properly, but may not; see below.
- "m̧" and "o̧" do not currently exist in Unicode as precombined glyphs, and must be encoded as the plain Latin letters "m" and "o" with the combining cedilla diacritic. Most Unicode fonts issued with Windows do not display combining diacritics properly, showing them too far to the right of the letter, as with Tahoma ("m̧" and "o̧") and Times New Roman ("m̧" and "o̧"). This mostly affects "m̧", and may or may not affect "o̧". But some common Unicode fonts like Arial Unicode MS ("m̧" and "o̧"), Cambria ("m̧" and "o̧") and Lucida Sans Unicode ("m̧" and "o̧") do not have this problem. When "m̧" is properly displayed, the cedilla is either underneath the center of the letter, or is underneath the right-most leg of the letter, but is always directly underneath the letter wherever it is positioned.
Because of these font display issues, it is not uncommon to find nonstandard ad hoc substitutes for these letters. The online version of the Marshallese-English Dictionary (the only complete Marshallese dictionary in existence) displays the letters with dot below diacritics, all of which do exist as precombined glyphs in Unicode: "ḷ", "ṃ", "ṇ" and "ọ". The first three exist in the International Alphabet of Sanskrit Transliteration, and "ọ" exists in the Vietnamese alphabet, and both of these systems are supported by the most recent versions of common fonts like Arial, Courier New, Tahoma and Times New Roman. This sidesteps most of the Marshallese text display issues associated with the cedilla, but is still inappropriate for polished standard text.
Languages such as Romanian add a comma (virgula) to some letters, such as ș, which looks like a cedilla, but is more precisely a diacritical comma. This is particularly confusing with letters which can take either diacritic: for example, the consonant /ʃ/ is written as "ş" in Turkish but "ș" in Romanian, and Romanian writers will sometimes use the former instead of the latter because of insufficient font or character-set support.
In 1868, Ambroise Firmin-Didot suggested in his book Observations sur l'orthographe, ou ortografie, française (Observations on French Spelling) that French phonetics could be better regularized by adding a cedilla beneath the letter "t" in some words. For example, the suffix -tion this letter is usually not pronounced as (or close to) /t/ in either French or English, but respectively as /sjɔ̃/ and /ʃən/. It has to be distinctly learned that in words such as French diplomatie (but not diplomatique) and English action it is pronounced /s/ and /ʃ/, respectively (but not in active in either language). A similar effect occurs with other prefixes or within words also in French and English, such as partial where t is pronounced /s/ and /ʃ/ respectively. Firmin-Didot surmised that a new character could be added to French orthography. A similar letter, the t-comma, does exist in Romanian, but it has a comma accent, not a cedilla.
The Unicode characters for Ţ (T with cedilla) and Ş (S with cedilla) were wrongly implemented in Windows-1250, the code page for Romanian. In Windows 7, Microsoft corrected the error by replacing T-cedilla with T-comma (Ț) and S-cedilla with S-comma (Ș).
Gagauz uses Ţ (T with cedilla), one of the few languages to do so, and Ş (S with cedilla). Besides being present in some Gagauz orthographies, T with Cedilla exists as part of the General Alphabet of Cameroon Languages, in the Kabyle dialect of the Berber language, and possibly elsewhere.
