C is the third letter of the Roman alphabet. In the Etruscan language, plosive consonants had no distinctive voicing, so they took over Greek Γ (Gamma) to write their /k/. In the beginning, the Romans used C for both /k/ and /g/, only later adding a horizontal bar at right-center to produce G. It 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 (gmel) pictured a camel. Phonetic use /k/ developed palatal and velar allophones in Latin, probably due to Etruscan influence. The Romance languages and English have a common feature inherited from Vulgar Latin where C takes on either a "hard" or "soft" value depending on the following vowel. In English and French, C takes the "hard" value voiceless velar plosive finally and before A, O, and U, and the "soft" value voiceless alveolar fricative before E, I, or Y. Romance languages obey similar rules, but the soft value is different in several languages, taking on /θ/ in European Castilian and (like English CH) in Italian and Romanian. Other languages use C with different values, such as regardless of position in Welsh, in Fijian, in Turkish, Tatar, Azeri, in Czech, Croatian, Esperanto, Hungarian, Romanized Chinese. There are several common digraphs with C, the most common being CH, which in some languages such as German is far more common than C alone. In English, CH most commonly takes the value , but can take the value or voiceless velar fricative, usually when transliterating Greek Χ or Hebrew. CH takes various values in other languages, such as Voiceless palatal fricative, , or in German, Voiceless postalveolar fricative in French, in Italian, in Mandarin Chinese, and so forth. CK, with the value , is often used after short vowels in Germanic languages such as English, German and Swedish. The digraph CZ is found in Polish and CS in Hungarian, both representing . 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.
