Ç

In many languages, ⟨ç⟩ represents the "soft" sound /s/ where a ⟨c⟩ would normally represent the "hard" sound /k/. These include:

• Catalan. Known as ce trencada ('broken C') in this language, where it can be used before ⟨a⟩, ⟨o⟩, ⟨u⟩ or at the end of a word. Some examples of words with ⟨ç⟩ are amenaça ('menace'), torçat ('twisted'), xoriço ('chorizo'), forçut ('strong'), dolç ('sweet') and caça ('hunting'). A well-known word with this character is Barça, a common Catalan clipping of Futbol Club Barcelona.
• French (cé cédille): français ('French'), garçon ('boy'), façade ('frontage'), grinçant ('squeaking'), leçon ('lesson'), reçu ('received' [past participle]). French does not use the character at the end of a word but it can occur at the beginning of a word (e.g., ça, 'that').^[1] It is never used in French where C would denote /s/ (before e, i, y) nor before h.
• Occitan (ce cedilha): torçut ('twisted'), çò ('this'), ça que la ('nevertheless'), braç ('arm'), brèç ('cradle'), voraç ('voracious'). It can occur at the beginning or end of words.
• Portuguese (cê-cedilha, cê de cedilhaorcê cedilhado): it is used before ⟨a⟩, ⟨o⟩, ⟨u⟩: taça ('cup'), braço ('arm'), açúcar ('sugar'). Modern Portuguese does not use the character at the beginning or at the end of a word (the nickname for ConceiçãoisSão, not Ção). According to a Portuguese grammar written in 1550, the letter ç had the sound of /dz/ around that time. Another grammar written around 1700 would say that the letter ç sounds like /s/, which shows a phonetic evolution that is still valid today.
• Old Galician used the ç letter, however it is no longer present in the official norm for the Galician language by the Royal Galician Academy. However, the unofficial norm for the Galician language by the AGAL reclaims the ç as part of the language.
• Old Spanish used ç to represent /t͡s/.
• Early Modern Spanish used the letter ç to represent either /θ/ or /s/ before /a/, /o/, and /u/ in much the same way as Modern Spanish uses the letter z. Middle Castilian Spanish pronounced ç as /θ/. Andalusian, Canarian, and Latin American Spanish pronounced ç as /s/. A spelling reform in the 18th century eliminated ç from Spanish orthography.

In other languages, it represents the voiceless postalveolar affricate /t͡ʃ/ (like ⟨ch⟩ in English chalk):

• Friulian (c cun cedilie) before ⟨a⟩, ⟨o⟩, ⟨u⟩ or at the end of a word.

InManx, it is used in the digraph ⟨çh⟩, which also represents /t͡ʃ/, to differentiate it from normal ⟨ch⟩, which represents /x/.

• InBasque, ⟨ç⟩ (known as ze hautsia) is used in the loanword Curaçao.
• InDutch, it can be found in some words from French and Portuguese, such as façade, reçu, Provençaals and Curaçao.
• InEnglish, ⟨ç⟩ is used in loanwords such as façade and limaçon (although the cedilla mark is often dropped: ⟨facade⟩, ⟨limacon⟩).

It represents the voiceless postalveolar affricate /t͡ʃ/ in the following languages:

• the 4th letter of the Albanian alphabet.
• the 4th letter of the Azerbaijani alphabet.
• the 4th letter of the Turkish alphabet.
• the 3rd letter of the Turkmen alphabet.
• the 4th letter of the Kurmanji alphabet (also known as Northern Kurdish).
• the 4th letter of the Zazaki alphabet.

In the 2020 version of the Latin Kazakh Alphabet, the letter represents the voiceless alveolo-palatal affricate /tɕ/, which is similar to /t͡ʃ/.

It previously represented a voiceless palatal click /ǂ/inJuǀʼhoansi and Naro, though the former has replaced it with ⟨ǂ⟩ and the latter with ⟨tc⟩.

The similarly shaped letter the (Ҫ ҫ) is used in the Cyrillic alphabets of Bashkir and Chuvash to represent /θ/ and /ɕ/, respectively.

InTatar, ç represents /ɕ/.

It also represents the retroflex flap /ɽ/ in the Rohingya Latin alphabet.

Janalif uses this letter to represent the voiced postalveolar affricate /d͡ʒ/

Old Malay uses ç to represent /dʒ/ and /ɲ/.

On Albanian, Belgian, European French, Portuguese, Spanish, Swiss, Turkish and Italian keyboards, Ç is directly available as a separate key; however, on most other keyboards, including the US and British keyboard, a combination of keys must be used:

• In the US-International keyboard layout, these are ' followed by either Cor⇧ Shift+C. Alternatively one may press AltGr+,orAltGr+⇧ Shift+,. The Canadian French layout has a dedicated dead key in the spot of the ] key.
• Inclassic Mac OS and macOS, these are ⌥ Opt+C and ⌥ Opt+⇧ Shift+C for lower- and uppercase, respectively.
• In the X Window System and many Unix consoles, one presses sequentially Compose, , and either Cor⇧ Shift+C. Alternatively, one may press AltGr+= and then either Cor⇧ Shift+C.
• InMicrosoft Windows, these are Alt+0231orAlt+135 for lowercase and Alt+0199orAlt+128 for uppercase.
• InMicrosoft Word, these are Ctrl+, and then either Cor⇧ Shift+C.
• The HTML character entity references are ç and Ç for lower- and uppercase, respectively.
• InTeX and LaTeX, \c is used for adding the cedilla accent to a letter, so \c{c} produces "ç".
