Mongolian script

The classical Mongolian script (in Mongolian script: ᠮᠣᠩᠭᠣᠯᠪᠢᠴᠢᠭ Mongγol bičig; in Mongolian Cyrillic: Монгол бичиг Mongol bichig), also known as Hudum Mongol bichig, was the first writing system created specifically for the Mongolian language, and was the most successful until the introduction of Cyrillic in 1946. Derived from Sogdian, Mongolian is a true alphabet, with separate letters for consonants and vowels. The Mongolian script has been adapted to write languages such as Oirat and Manchu. Alphabets based on this classical vertical script are used in Inner Mongolia and other parts of China to this day to write Mongolian, Xibe and, experimentally, Evenki.

History

The Mongolian vertical script developed as an adaptation of the Sogdian to the Mongolian language. From the seventh and eighth to the fifteenth and sixteenth centuries, the Mongolian language separated into southern, eastern and western dialects. The principal monuments of the middle period are: in the eastern dialect, the famous Secret History of the Mongols, monuments in the square script, materials of the Chinese-Mongolian glossary of the fourteenth century, and materials of the Mongolian language of the middle period in Chinese transcription, etc.; in the western dialect, materials of the Arab-Mongolian and Persian-Mongolian dictionaries, Mongolian texts in Arabic transcription, etc. The main features of the period are that the vowels ï and i had lost their phonemic significance, creating the i phoneme (in Chahar dialect, the Standard Mongolian in Inner Mongolia, they're still distinct); intervocal consonants γ/g, b/w had disappeared and the preliminary process of the formation of Mongolian long vowels had begun; the initial h was preserved in many words; grammatical categories were partially absent, etc. The development over this period explains why Mongolian script looks like a vertical Arabic script (in particular the presence of the dots system).

Traditional Mongolian alphabet

The traditional or classical Mongolian alphabet, sometimes called Hudum 'traditional' in Oirat in contrast to the Clear script (Todo 'exact'), is the original form of the Mongolian script used to write the Mongolian language. It does not distinguish several vowels (o/u, ö/ü, final a/e) and consonants (t/d, k/g, sometimes ž/y) that were not required for Uyghur, which was the source of the Mongol (or Uyghur-Mongol) script. The result is somewhat comparable to the situation of English, which must represent ten or more vowels with only five letters and uses the digraph th for two distinct sounds. Ambiguity is sometimes prevented by context, as the requirements of vowel harmony and syllable sequence usually indicate the correct sound. Moreover, as there are few words with an exactly identical spelling, actual ambiguities are rare for a reader who knows the orthography.

Letters have different forms depending on their position in a word: initial, medial, or final. In some cases, additional graphic variants are selected for visual harmony with the subsequent character.
