C with bar

The C with bar (majuscule: Ꞓ, minuscule: ꞓ), also known as barred C, is a modified letter of the Latin alphabet, formed from C with the addition of a bar. It was used in the final version of the Unified Northern Alphabet, approved in 1932, for Saami, Selkup, Khanty, Evenki, Even, Nanai, Udege, Chukchi, Koryak and Nivkh languages ^[1] to denote the sound IPA: [t͡ʃ], although in some of these languages in practice, several other alphabets were used. Also, this letter was used in the Latinized Shugnan alphabet (1931-1939) to denote the sound IPA: [t͡s].^[2][3][4]

The United States Federal Geographic Data Committee uses the capital barred C to represent the Cambrian Period in geologic history.^[5] In phonetic transcription, the lowercase barred C may denote a voiceless palatal fricative (IPA: [ç]), and in 1963, it was proposed as a symbol for a voiceless flat postalveolar fricative [ɻ̊˔] by William A. Smalley.^[6]

In 19th-century American English dictionaries such as those by Noah Webster and William Holmes McGuffey, the letter was used to denote ⟨c⟩ pronounced as /k/.^[7]
