Ch (digraph)
Ch is a digraph in the Latin script. It is treated as a letter of its own in Chamorro, Old Spanish, Czech, Slovak, Igbo, Kazakh, Uzbek, Quechua, Guarani, Welsh, Cornish, Breton, Ukrainian Łatynka and Belarusian Łacinka alphabets. In Vietnamese and Modern Spanish, it also used to be considered a letter for collation purposes but this is no longer common. History. The digraph was first used in Latin since the 2nd century B.C. to transliterate the sound of the Greek letter chi in words borrowed from that language. In classical times, Greeks pronounced this as an aspirated voiceless velar  plosive . In post-classical Greek (Koine and Modern) this sound developed into a fricative . Since neither sound was found in native Latin words (with some exceptions like "pulcher" 'beautiful', where the original sound was influenced by or ), in Late Latin the pronunciation occurred. In Old French, a language that had no or and represented by "c", "k", or "qu", "ch" began to be used to represent the voiceless palatal plosive , which came from in some positions and later became and then . Now the digraph "ch" is used for all the aforementioned sounds, as shown below. The Old French usage of  ch was also a model of several other digraphs for palatals or postalveolars: lh (digraph), nh (digraph), sh (digraph). Use by language. Balto-Slavic languages. In Balto-Slavic languages that use the Latin alphabet instead of the Cyrillic alphabet, "ch" represents the voiceless velar fricative . "Ch" is used in the Lithuanian language to represent the "soft h" , in word choras [ˈxɔrɐs̪] "choir". This digraph is not considered a single letter in the Lithuanian alphabet.

The letter "ch" is a digraph consisting of the sequence of Latin alphabet  graphemes C and H, however it is a single phoneme (pronounced as a voiceless velar fricative ) and represents a single entity in Czech collation order, inserted between "H" and "I". In capitalized form, "Ch" is used at the beginning of a sentence ("Chechtal se." "He giggled."), while "CH" or "Ch" can be used for standalone letter in lists etc. and only fully capitalized "CH" is used when the letter is a part of an abbreviation (e.g. "CHKO Beskydy") and in all-uppercase texts. In the Czech alphabet, the digraph "Ch" is handled as a letter equal to other letters. In  Czech dictionaries, indexes, and other alphabetical lists, it has its own section, following that of words (including names) beginning with "H" and preceding that of words that begin with "I". Thus, the word "chemie" will not be found in the "C" section of a Czech dictionary, nor the name "Chalupa" in the "C" section of the phonebook. The alphabetical order "h" "ch" is observed also when the combination "ch" occurs in median or final position: "Praha" precedes "Prachatice", "hod" precedes "hoch". Polish. "Ch" had been used in the Polish language to represent the "soft h" as it is pronounced in  the Polish word chleb "bread", and the "h" to represent "hard h", where it is distinct, as it is pronounced in the Polish word hak "hook". Between World War I and World War II, the Polish intelligentsia used to exaggerate the "hardness" of the hard Polish h to aid themselves in proper spelling. In most present-day Polish dialects, however, "ch" and "h" are uniformly merged as . Slovak. In Slovak, "ch" represents , and more specifically in voiced position. At the beginning of a sentence it is used in two different variants: "CH" or "Ch". It can be followed by a  consonant ("chladný" "cold"), a vowel ("chémia" "chemistry") or diphthong ("chiazmus" "chiasmus"). Only a few Slovak words treat "CH" as two separate letters, e.g., "viachlasný" (e.g. "multivocal" performance), from "viac" ("multi") and "hlas" ("voice"). In the Slovak alphabet, it comes between "H" and "I". Celtic languages. In Goidelic languages, "ch" represents the voiceless velar fricative . In Irish, "ch" stands for when broad and (or between vowels) when slender.

Chamorro. "Ch" is the fifth letter of the Chamorro language and its sound is . The Chamorro Language has three different dialects - the Guamanian dialect, the Northern Mariana Islands dialect, and the Rotanese dialect. With the minor difference in dialect, the Guamanians have a different orthography from the other two dialects. In Guamanian  orthography, both letters tend to get capitalized (e.g.: "CHamoru"). The Northern Mariana Islands' & Rotanese orthography enforces the standard capitalization rule (e.g.: "Chamorro"). Germanic languages. In several Germanic languages, including German and Yiddish, "ch" represents the voiceless velar fricative . In Rheinische Dokumenta, "ch" represents , as opposed to "ch", which stands for . Dutch. Dutch "ch" was originally voiceless, while "g" was voiced. In the northern Netherlands, both "ch" and "g" are voiceless, while in the southern Netherlands and Flanders the voiceless/voiced distinction is upheld. The voiceless fricative is pronounced [x] or [χ] in the north and [ç] in the south, while  the voiced fricative is pronounced [ɣ] in the north (i.e. the northern parts of the area that still has this distinction) and [ʝ] in the south. This difference of pronunciation is called 'hard and soft g'. English.

Until 1994 "ch" was treated as a single letter in Spanish  collation order, inserted between C and D; in this way, "mancha" was after "manco" and before "manda". However, an April 1994 vote in the 10th Congress of the Association of Spanish Language Academies adopted the standard international collation rules, so "ch" is now considered a sequence of two distinct characters, and dictionaries now place words starting with "ch-" between those starting with "ce-" and "ci-", as there are no words that start with "cf-" or "cg-" in Spanish. Similarly, "mancha" now precedes "manco" in alphabetical order. Kazakh. "Ch" was selected to represent in the Kazakh Latin alphabet. It was considered  a separate letter, and was the 32nd and last letter of the alphabet in the 2018 amendment. As part of the switch of Kazakh from Cyrillic to Latin, the initial proposed Latin alphabet in 2017 (implemented by Presidential Decree 569 of 26 October 2017) tried to avoid the use of accent marks and digraphs in representing certain phonemes. Initially, /t͡ɕ/ would have been represented by ⟨C'⟩. This was revised by Presidential Decree 637 of 19 February 2018, replacing the apostrophe with the digraph ⟨Ch⟩. However, in the late 2019, under president Tokayev's amendment suggestions, the Ch has been removed  from alphabet. Other languages.
