C


C is the third letter of the Roman alphabet. In the Etruscan language, plosive consonants had no distinctive voicing, so they took over Greek &Gamma (Gamma) to write their /k/.\nIn the beginning, the Romans used C for both /k/ and /g/, only later adding a horizontal bar at right-center to produce G.\nIt is possible but uncertain that C represented only /g/ at an even earlier time, while K might have been used for /k/. Some scholars claim that the Semitic ג (gîmel) pictured a camel.\n/k/ developed palatal and velar allophones in Latin, probably due to Etruscan influence.\nTherefore, C has many different sound values today, among them /k/ and /s/ in French, /k/ and /θ/ (like English TH in THIN) in European Castilian, /θ/ in Fijian, /k/ and /ʧ/ (like English CH) in Italian, /ʤ/ in Turkish, Tatar, Azeri; /ʦ/ in Czech, Esperanto and so on. As a phonetic symbol, lowercase [c] is the International Phonetic Alphabet and X-SAMPA symbol for the voiceless palatal plosive, and capital [C] is the X-SAMPA symbol for the voiceless palatal fricative. Charlie represents the letter C in the NATO phonetic alphabet.

"In science one tries to tell people, in such a way as to be understood by everyone, something that no one ever knew before. But in poetry, it's the exact opposite." - Paul Dirac (1902-1984)
