Collation in the context of "Indic scripts"

Ch is a digraph in the Latin script. It is treated as a letter of its own in the Chamorro, Old Spanish, Czech, Slovak, Igbo, Uzbek, Quechua, Ladin, Guarani, Welsh, Cornish, Breton, Ukrainian Latynka, and Belarusian Łacinka alphabets. Formerly, ch was also considered a separate letter for collation purposes in Modern Spanish, Vietnamese, and sometimes in Polish; now the digraph ch in these languages continues to be used, but it is considered as a sequence of letters and sorted as such.

The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.

Al- (Arabic: ٱلْـ, also romanized as el-, il-, and l- as pronounced in some varieties of Arabic), is the definite article in the Arabic language: a particle (ḥarf) whose function is to render the noun on which it is prefixed definite. For example, the word كتاب kitāb "book" can be made definite by prefixing it with al-, resulting in الكتاب al-kitāb "the book". Consequently, al- is typically translated as "the" in English.

Unlike most other Arabic particles, al- is always prefixed to another word and never stands alone. Consequently, many dictionaries do not list it, and it is almost invariably ignored in collation, as it is not an intrinsic part of the word.

A Chinese–English Dictionary (1892), compiled by the British consular officer and sinologist Herbert Allen Giles (1845–1935), is the first Chinese–English encyclopedic dictionary. Giles started compilation after being rebuked for criticizing mistranslations in Samuel Wells Williams' (1874) A Syllabic Dictionary of the Chinese Language. The 1,461-page first edition contains 13,848 Chinese character head entries alphabetically collated by Beijing Mandarin pronunciation romanized in the Wade–Giles system, which Giles created as a modification of Thomas Wade's (1867) system. Giles' dictionary furthermore gives pronunciations from nine regional varieties of Chinese, and three Sino-Xenic languages Japanese, Korean, and Vietnamese. Giles revised his dictionary into the 1,813-page second edition (1912) with the addition of 67 entries and numerous usage examples.

Alphabetical order is a system whereby character strings are placed in order based on the position of the characters in the conventional ordering of an alphabet. It is one of the methods of collation. In mathematics, a lexicographical order is the generalization of the alphabetical order to other data types, such as sequences of numbers or other ordered mathematical objects.

When applied to strings or sequences that may contain digits, numbers or more elaborate types of elements, in addition to alphabetical characters, the alphabetical order is generally called a lexicographical order.
