Caron


A caron, háček or haček also known as a hachek, wedge, check, kvačica, mäkčeň, inverted circumflex, inverted hat, flying bird, is a diacritic commonly placed over certain letters in the orthography of some Baltic, Slavic, Finnic, Samic, Berber, and other languages to indicate a change in the related letter's pronunciation.
The use of the caron differs according to the orthographic rules of a language. In most Slavic and European languages it indicates present or historical palatalization, iotation, or postalveolar articulation. In Salishan languages, it often represents a uvular consonant
When placed over vowel symbols, the caron can indicate a contour tone, for instance the falling and then rising tone in the Pinyin romanization of Mandarin Chinese.
It is also used to decorate symbols in mathematics, where it is often pronounced .
It looks similar to a breve, but has a sharp tip, like an inverted circumflex, while a breve is rounded.

The left stroke is usually thicker than the right stroke in serif typefaces.

Names

Different disciplines generally call this diacritic by different names. Typography tends to use the term caron. Linguistics more often uses haček, largely due to the influence of the Prague School. Pullum's and Ladusaw's Phonetic Symbol Guide uses the term wedge.
The term caron is used in the official names of Unicode characters. Its earliest known use was in the United States Government Printing Office Style Manual of 1967, and it was later used in character sets such as DIN 31624, ISO 5426, ISO/IEC 6937 and ISO/IEC 8859-2. Its actual origin remains obscure, but some have suggested that it may derive from a fusion of caret and macron. Though this may be folk etymology, it is plausible, particularly in the absence of other suggestions.
The Oxford English Dictionary gives 1953 as the earliest citation for háček. In Czech, háček means "small ", the diminutive form of hák, "hook". The name appears in most English dictionaries, but they treat the long mark differently. British dictionaries, such as the OED, ODE, CED, write háček in the headwords, while American ones, such as the Merriam-Webster, NOAD, AHD, omit the acute and write haček, however, the NOAD gives háček as an alternative spelling.
In Slovak it is called mäkčeň, in Serbo-Croatian kvaka or kvačica, in Slovenian strešica or kljukica, in Lithuanian paukščiukas or varnelė, in Estonian katus, in Finnish hattu, and in Lakota ičášleče.

Origin

The caron evolved from the dot above diacritic, which Jan Hus introduced into Czech orthography in his De Orthographia Bohemica. The original form still exists in Polish ż. However, Hus's work was hardly known at that time, and háček became widespread only in the 16th century with the introduction of printing.

Usage

For the fricatives š, ž, and the affricate č only, the caron is used in most northwestern Uralic languages that use the Latin alphabet, such as Karelian, Veps, Northern Sami and Inari Sami. Estonian and Finnish use š and ž, but only for transcribing foreign names and loanwords ; the sounds are native and common in Karelian, Veps and Sami.
In Italian, š, ž, and č are routinely used as in Slovenian to transcribe Slavic names in the Cyrillic script since in native Italian words, the sounds represented by these letters must be followed by a vowel, and Italian uses ch for, not. Other Romance languages, by contrast, tend to use their own orthographies, or in a few cases such as Spanish, borrow English sh or zh.
The caron is also used in the Romany alphabet. The Faggin-Nazzi writing system for the Friulian language makes use of the caron over the letters c, g, and s.
The caron is also often used as a diacritical mark on consonants for romanization of text from non-Latin writing systems, particularly in the scientific transliteration of Slavic languages. Philologists and the standard Finnish orthography often prefer using it to express sounds for which English require a digraph because most Slavic languages use only one character to spell the sounds. Its use for that purpose can even be found in the United States because certain atlases use it in romanization of foreign place names. On the typographical side, Š/š and Ž/ž are likely the easiest among non-Western European diacritic characters to adopt for Westerners because the two are part of the Windows-1252 character encoding.
Esperanto uses the circumflex over c, g, j and s in similar ways; the circumflex was chosen because there was no caron on most Western European typewriters, but the circumflex existed on French ones.
It is also used as an accent mark on vowels to indicate the tone of a syllable. The main example is in Pinyin for Chinese in which it represents a falling-rising tone. It is used in transliterations of Thai to indicate a rising tone.

Phonetics

The caron represents a rising tone in the International Phonetic Alphabet. It is used in the Uralic Phonetic Alphabet for indicating postalveolar consonants and in Americanist phonetic notation to indicate various types of pronunciation.
The caron below represents voicing.

Writing and printing carons

In printed Czech and Slovak text, the caron combined with certain letters is reduced to a small stroke. That is optional in handwritten text.
In Lazuri orthography, the lower-case k with caron sometimes has its caron reduced to a stroke while the lower-case t with caron preserves its caron shape.
Although the stroke looks similar to an apostrophe, there is a significant difference in kerning. Using an apostrophe in place of a caron looks very unprofessional, but it can be found on goods produced in foreign countries and imported to Slovakia or the Czech Republic. Foreigners also sometimes mistake the caron for the acute accent.

List of letters

Balto-Slavic

The following are the Czech and Slovak letters and digraphs with the caron :
In the Lower Sorbian and Upper Sorbian languages, the following letters and digraphs have the caron:
Balto-Slavic Serbo-Croatian, Slovenian, Latvian and Lithuanian use č, š and ž. The digraph dž is also used in these languages but is considered a separate letter only in Serbo-Croatian. The Belarusian Lacinka alphabets also contain the digraph, and Latin transcriptions of Bulgarian and Macedonian may use them at times, for transcription of the letter-combination ДЖ and the letter Џ.

Uralic

Of Uralic languages, Estonian use Š/š and Ž/ž, and Karelian and some Sami languages use Č/č, Š/š and Ž/ž. Dž is not a separate letter. Č is present because it may be phonemically geminate: in Karelian, the phoneme 'čč' is found, and is distinct from 'č', which is not the case in Finnish or Estonian, for which only one length is recognized for 'tš'. On some Finnish keyboards, it is possible to write those letters by typing s or z while holding right Alt key or AltGr key.
Notice that they are not palatalized but postalveolar consonants. For example, Estonian Nissi is distinct from nišši. Palatalization is typically ignored in spelling, but some Karelian and Võro orthographies use an apostrophe or an acute accent. In Finnish and Estonian, š and ž appear in loanwords and foreign proper names only and when not available, they can be substituted with 'h': 'sh' for 'š', in print.
Skolt Sami uses Ʒ/ʒ to mark the alveolar affricate, thus Ǯ/ǯ marks the postalveolar affricate. In addition to Č, Š, Ž and Ǯ, Skolt Sami also uses the caron to mark palatal stops Ǧ and Ǩ. More often than not, they are geminated: vuäǯǯad "to get".

Others

Finnish Romani uses Ȟ/ȟ.
Lakota uses Č/č, Š/š, Ž/ž, Ǧ/ǧ and Ȟ/ȟ.
The DIN 31635 standard for transliteration of Arabic uses Ǧ/ǧ to represent the letter ج. ǧīm, on account of the inconsistent pronunciation of J in European languages, the variable pronunciation of the letter in educated Arabic, and the desire of the DIN committee to have a one-to-one correspondence of Arabic to Latin letters in its system.
Romanization of Pashto uses Č/č, Š/š, Ž/ž, X̌/x̌, to represent the letters چ, ش, ژ, ښ, respectively. Additionally, Ṣ̌/ṣ̌ and Ẓ̌/ẓ̌ are used by the southern Pashto dialect only.
The latter Š/š is also used to transcribe the phoneme in Sumerian and Akkadian cuneiform, and the phoneme in Semitic languages represented by the letter shin.

Other uses

The caron is also used in Mandarin Chinese pinyin romanization and orthographies of several other tonal languages to indicate the "falling-rising" tone. The caron can be placed over the vowels: ǎ, ě, ǐ, ǒ, ǔ, ǚ. The alternative to a caron is a number 3 after the syllable: hǎo = hao3, as the "falling-rising" tone is the third tone in Mandarin.
The caron is used in the New Transliteration System of D'ni in the symbol š to represent the sound .
Many alphabets of African languages use the caron to mark the rising tone, as in the African reference alphabet.
The caron is also used for Cypriot Greek letters that have a different sound from Standard Modern Greek: σ̌ κ̌ π̌ τ̌ ζ̌ in words like τζ̌αι, κάτ̌τ̌ος.
A-caron is also used to transliterate the Cyrillic letter Ъ in Bulgarian-it represents the mid back unrounded vowel.
Paiboon romanizations of Thai uses the caron to indicate the fifth tone of Thai.

Software

Unicode

For legacy reasons, most letters that carry carons are precomposed characters in Unicode, but a caron can also be added to any letter by using the combining character, for example: b̌ q̌ J̌.
The characters Č, č, Ě, ě, Š, š, Ž, ž are a part of the Unicode Latin Extended-A set because they occur in Czech and other official languages in Europe, while the rest are in Latin Extended-B, which often causes an inconsistent appearance.
Unicode also encodes, for example: p̬.
