Ç or ç (C with cedilla, broken C) is a Latin script letter used in the Albanian, Azerbaijani, Manx, Tatar, Turkish, Turkmen, Kurdish, Kazakh, Uzbek, and Romance alphabets. Romance languages that use this letter include Catalan, French, Portuguese, and Occitan, as a variant of the letter C with a cedilla. It is also occasionally used in Crimean Tatar and in Tajik (when written in the Latin script) to represent the /d͡ʒ/ sound. It is rarely used in Balinese, usually only in the word "Çaka" during Nyepi, one of the Balinese Hinduism holidays. It is often retained in the spelling of loanwords from any of these languages in English, Basque, Dutch, Spanish and other languages using the Latin alphabet.

It was first used for the sound of the voiceless alveolar affricate /t͡s/ in Old Catalan as a simplification of "Ci".
It also originated in Old Spanish, where it stems from the Visigothic form of the letter z ⟨Ꝣ⟩.
The phoneme originated in Vulgar Latin from the palatalization of the plosives /t/ and /k/ in some conditions. Later, /t͡s/ changed into /s/ in many Romance languages and dialects. Spanish has not used the symbol since an orthographic reform in the 18th century (which replaced ç with the z, which has now been shifted to /θ/ or to /s/), but it was adopted for writing other languages.

In many languages, ⟨ç⟩ represents the "soft" sound /s/ where a ⟨c⟩ would normally represent the "hard" sound /k/. These include:
In other languages, it represents the voiceless postalveolar affricate /t͡ʃ/ (like ⟨ch⟩ in English chalk):
It represents the voiceless postalveolar affricate /t͡ʃ/ in the following languages:

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/ in Juǀʼhoansi 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.
It also represents the retroflex flap /ɽ/ in the Rohingya Latin alphabet.
Janalif uses this letter to represent the voiced postalveolar affricate /d͡ʒ/
On Albanian, Belgian, European French, Portuguese, Spanish, Swiss, Turkish and Italian keyboards, Ç is directly available as a separate key. On most other keyboards, other methods must be used. It can also be typed with Alt+0199 (capital) and Alt+0231 (small).
