History

The letter "C" has a long history. It shares its roots with the letter "G". The ancient Semites called this letter gimel. It may have been inspired by an Egyptian hieroglyph for a staff sling or perhaps showed a camel, whose Semitic name was gamal.

In the early days of the Latin alphabet, the letters "c", "k", and "q" all showed the same sounds. Over time, "c" was chosen to show one specific sound, and a new letter "g" was made for another. This is why we now use "c" and "g" separately. Later, when the Romans spread their alphabet, the letter "c" took on different sounds based on the letter that followed it. This tradition continues in modern languages, including English.

English

In English, the letter c usually makes the /s/ sound before the letters e, i, and y, and the /k/ sound before other letters or at the end of a word. There are exceptions, like in the words "soccer", "celt", and "sceptic", where it makes the /k/ sound even when we might expect /s/. The c can also make the /ʃ/ sound in words like "delicious" and "appreciate," especially when followed by the letter i.

The combination ch most often makes the /tʃ/ sound, but it can also make the /k/ sound in words from Greek or the /ʃ/ sound in words from French. In some dialects, ch can make the /x/ sound, as in the word "loch." The combination ck is often used to show the /k/ sound after short vowels, like in the word "wicket."

C is the twelfth most frequently used letter in the English language.

Other languages

In many Romance languages like French, Spanish, Italian, Romanian, Catalan, and Portuguese, c usually makes the /k/ sound and a softer sound that changes depending on the language. In French, Portuguese, Catalan, and some types of Spanish, the soft c makes the /s/ sound. In most of Spain’s Spanish, it makes a special /θ/ sound. In Italian and Romanian, the soft c makes the /t͡ʃ/ sound.

Germanic languages often use c in borrowed words or in combinations like ch and ck, but rules differ. Only English uses c at the start of its own words, like in "come." Dutch uses c the most for borrowed words and in ch. German uses c in ch, ck, and sch, but alone only in foreign words and names. Danish keeps the soft c in borrowed words but changes hard c to k. Swedish follows similar rules and uses c in ck and in the common word "och," meaning "and." Norwegian, Afrikaans, and Icelandic mostly replace c with k or s, saving c for foreign words and names.

Many languages that use the Latin alphabet, like Balto-Slavic languages, Albanian, Hungarian, Pashto, several Sami languages, Esperanto, Ido, Interlingua, and Americanist phonetic notation, use c for the /t͡s/ sound. In Hanyu Pinyin, the system for writing Mandarin Chinese, c represents an aspirated version of this sound, /t͡s^h/.

In non-European languages using the Latin alphabet, c represents many different sounds. In Yup'ik, Indonesian, Malay, and some African languages like Hausa, Fula, and Manding, c makes the /t͡ʃ/ sound. In Azeri, Crimean Tatar, Kurmanji Kurdish, and Turkish, it makes the /d͡ʒ/ sound. In Yabem and similar languages, c stands for the /ʔ/ sound. Xhosa and Zulu use c for a click sound /ǀ/. In some African languages like Berber languages, c makes the /ʃ/ sound. In Fijian, it makes the /ð/ sound, while in Somali, it makes the /ʕ/ sound.

The letter c is also used to represent the Cyrillic letter ц in the Latin versions of Serbian, Macedonian, and sometimes Ukrainian, along with the combination ts.

Other systems

As a phonetic symbol, the lowercase c is used in the International Phonetic Alphabet and X-SAMPA to show the /voiceless palatal plosive/, and the uppercase C is the X-SAMPA symbol for the /voiceless palatal fricative/.

Digraphs

There are several common combinations with c, the most common being ch, which in some languages like German is used far more than c alone. ch can have different sounds in other languages.

As in English, ck, making the /k/ sound, is often used after short vowels in other Germanic languages like German and Swedish. Other Germanic languages like Dutch and Norwegian use kk instead. The combination cz is found in Polish and cs in Hungarian, making /t͡ʂ/ and /t͡ʃ/ sounds respectively. The combination sc makes the /ʃ/ sound in Old English, Italian, and some Italian-related languages (only before front vowels), while otherwise it makes the /sk/ sound. The combination sch makes the /ʃ/ sound in German.
