C, or c, is the third letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is cee (pronounced /ˈsiː/), plural cees.^[1]

Egyptian	Phoenician gaml	Western Greek Gamma	Etruscan C	Old Latin C (G)	Latin C

"C" comes from the same letter as "G". The

Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical Etruscan. In Latin, it eventually took the 'c' form in Classical Latin. In the earliest Latin inscriptions, the letters 'c k q' were used to represent the sounds /k/ and /ɡ/ (which were not differentiated in writing). Of these, 'q' was used to represent /k/ or /ɡ/ before a rounded vowel, 'k' before 'a', and 'c' elsewhere.^[3]

In Vulgar Latin, /k/ became palatalized to [tʃ] in Italy and Dalmatia; in France and the Iberian Peninsula, it became [ts]. Yet for these new sounds, ⟨c⟩ was still used before the letters ⟨e⟩ and ⟨i⟩. The letter thus represented two distinct values. Subsequently, the Latin phoneme /k^w/ (spelled ⟨qv⟩) de-labialized to /k/, meaning that the various Romance languages had /k/ before front vowels. In addition, Norman used the letter ⟨k⟩ so that the sound /k/ could be represented by either ⟨k⟩ or ⟨c⟩, the latter of which could represent either /k/ or /ts/ depending on whether it preceded a front vowel letter or not. The convention of using both ⟨c⟩ and ⟨k⟩ was applied to the writing of English after the Norman Conquest, causing a considerable re-spelling of the Old English words. Thus, while Old English candel, clif, corn, crop, and cú, remained unchanged, cent, cǣᵹ (cēᵹ), cyng, brece, and sēoce, were now (without any change of sound) spelled Kent, keȝ, kyng, breke, and seoke; even cniht ('knight') was subsequently changed to kniht, and þic ('thick') was changed to thik or thikk. The Old English ⟨cw⟩ was also at length displaced by the French ⟨qu⟩ so that the Old English cwēn ('queen') and cwic ('quick') became Middle English quen and quik, respectively.

The sound [tʃ], to which Old English palatalized /k/ had advanced, also occurred in French, chiefly from Latin /k/ before ⟨a⟩. In French, it was represented by the digraph ⟨ch⟩, as in champ (from Latin camp-um), and this spelling was introduced into English: the Hatton Gospels, written c. 1160, have in Matt. i-iii, child, chyld, riche, and mychel, for the cild, rice, and mycel of the Old English version whence they were copied. In these cases, the Old English ⟨c⟩ gave way to ⟨k⟩, ⟨qu⟩ and ⟨ch⟩; on the other hand, ⟨c⟩ in its new value of /ts/ appeared largely in French words like processiun, emperice, and grace and was also substituted for ⟨ts⟩ in a few Old English words, as miltse, bletsien, in early Middle English milce, blecien. By the end of the thirteenth century, both in France and England, this sound /ts/ was de-affricated to /s/; and from that time, ⟨c⟩ has represented /s/ before front vowels either for etymological reasons, as in lance, cent, or to avoid the ambiguity due to the "etymological" use of ⟨s⟩ for /z/, as in ace, mice, once, pence, defence.

Thus, to show etymology, English spelling has advise, devise (instead of *advize, *devize), while advice, device, dice, ice, mice, twice, etc., do not reflect etymology; example has extended this to hence, pence, defence, etc., where there is no etymological reason for using ⟨c⟩. Former generations also wrote sence for sense. Hence, today, the Romance languages and English have a common feature inherited from Vulgar Latin spelling conventions where ⟨c⟩ takes on either a "hard" or "soft" value depending on the following letter.

In

C is the twelfth most frequently used letter in the English language (after E, T, A, O, I, N, S, H, R, D, and L), with a frequency of about 2.8% in words.

In the Romance languages French, Spanish, Italian, Romanian, and Portuguese, ⟨c⟩ generally has a "hard" value of /k/ and a "soft" value whose pronunciation varies by language. In French, Portuguese, Catalan, and Spanish from Latin America and some places in Spain, the soft ⟨c⟩ value is /s/ as it is in English. In the Spanish spoken in most of Spain, the soft ⟨c⟩ is a voiceless dental fricative /θ/. In Italian and Romanian, the soft ⟨c⟩ is [t͡ʃ].

Germanic languages usually use ⟨c⟩ for Romance loans or digraphs, such as ⟨ch⟩ and ⟨ck⟩, but the rules vary across languages. Of all the Germanic languages, only English uses the initial ⟨c⟩ in native Germanic words like come. Other than English,

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. ⟨ch⟩ takes various values in other languages.

As in English, ⟨ck⟩, with the value /k/, is often used after short vowels in other Germanic languages such as German and Swedish (other Germanic languages, such as Dutch and Norwegian, use ⟨kk⟩ instead). The digraph ⟨cz⟩ is found in Polish and ⟨cs⟩ in Hungarian, representing /t͡ʂ/ and /t͡ʃ/ respectively. The digraph ⟨sc⟩ represents /ʃ/ in Old English, Italian, and a few languages related to Italian (where this only happens before front vowels, while otherwise it represents /sk/). The trigraph ⟨sch⟩ represents /ʃ/ in German.
