# ʼPhags-pa script

The Phagspa /ˈpɑːɡzpɑː, ˈpɑːspɑː/, ʼPhags-pa or ḥPʻags-pa script is an alphabet designed by the Tibetan monk and State Preceptor (later Imperial Preceptor) Drogön Chögyal Phagpa (1235–1280) for Kublai Khan (r. 1264–1294), the founder of the Yuan dynasty (1271–1368) in China, as a unified script for the written languages within the Yuan. The actual use of this script was limited to about a hundred years during the Mongol-led Yuan dynasty, and it fell out of use with the advent of the Ming dynasty.
The script was used to write and transcribe varieties of Chinese, the Tibetic languages, Mongolian, the Uyghur language, Sanskrit, probably Persian, and other neighboring languages during the Yuan era. For historical linguists, its use provides clues about changes in these languages.
Its descendant systems include Horizontal square script, used to write Tibetan and Sanskrit. During the Pax Mongolica the script even made numerous appearances in Western medieval art.

## History

During the Mongol Empire, the Mongol rulers wanted a universal script to write down the languages of the people they subjugated. The Uyghur-based Mongolian alphabet was not a perfect fit for the Middle Mongol language, and it would have been impractical to extend it to a language with a very different phonology like Chinese. Therefore, during the Yuan dynasty (c. 1269), Kublai Khan asked the Tibetan monk ʼPhags-pa to design a new alphabet for use by the whole empire. ʼPhags-pa extended his native Tibetan alphabet to encompass Mongol and Chinese, evidently Central Plains Mandarin. The resulting 38 letters have been known by several descriptive names, such as "square script", based on their shape, but today, are primarily known as the ʼPhags-pa alphabet.
Descending from Tibetan script, it is part of the Brahmic family of scripts, which includes Devanagari and scripts used throughout Southeast Asia and Central Asia. It is unique among Brahmic scripts in that it is written from top to bottom, like how classical Chinese used to be written; and like the Manchu alphabet or later Mongolian alphabet is still written.
It did not receive wide acceptance and was not a popular script even among the elite Mongols themselves, although it was used as an official script of the Yuan dynasty until the early 1350s, when the Red Turban Rebellion started. After this, it was mainly used as a phonetic gloss for Mongols learning Chinese characters. In the 20th century, it was also used as one of the scripts on Tibetan currency, as a script for Tibetan seal inscriptions from the Middle Ages up to the 20th century, and for inscriptions on the entrance doors of Tibetan monasteries.

## Syllable formation

Although it is an alphabet, ʼPhags-pa is written like a syllabary or abugida, with letters forming a single syllable glued or 'ligated' together.
Top: Approximate values in Middle Chinese. (Values in parentheses were not used for Chinese.)
Second: Standard letter forms.
Third: Seal script forms. (A few letters, marked by hyphens, are not distinct from the preceding letter.)
Unlike the ancestral Tibetan script, all ʼPhags-pa letters are written in temporal order (that is, /CV/ is written in the order C–V for all vowels) and in-line (that is, the vowels are not diacritics). However, vowel letters retain distinct initial forms, and short /a/ is not written except initially, making ʼPhags-pa transitional between an abugida, a syllabary, and a full alphabet. The letters of a ʼPhags-pa syllable are linked together so that they form syllabic blocks.

## Typographic forms

ʼPhags-pa was written in a variety of graphic forms. The standard form (top, at right) was blocky, but a "Tibetan" form (bottom) was even more so, consisting almost entirely of straight orthogonal lines and right angles. A "seal script" form (Chinese: 蒙古篆字; pinyin: měnggǔ zhuànzì; "Mongolian Seal Script"), used for imperial seals and the like, was more elaborate, with squared sinusoidal lines and spirals. This ʼPhags-pa script is different from the ʼPhags-pa script, or 八思巴字 in Chinese, that shares the same name but its earliest usage can be traced back to the late 16th century, the early reign of Wanli Emperor. According to Professor Junast 照那斯图 of the Chinese Academy of Social Sciences, the later ʼPhags-pa script is actually a seal script of Tibetan.
Korean records state that Hangul was based on an "Old Seal Script" (古篆字), which may be ʼPhags-pa and a reference to its Chinese name Chinese: 蒙古篆字; pinyin: měnggǔ zhuànzì (see origin of Hangul). However, it is the simpler standard form of ʼPhags-pa that is the closer graphic match to Hangul.

## Letters
### Basic letters

The following 41 are the basic ʼPhags-pa letters.
Letters 1-30 and 35-38 are base consonants. The order of Letters 1-30 is the same as the traditional order of the thirty basic letters of the Tibetan script, to which they correspond. Letters 35-38 represent sounds that do not occur in Tibetan, and are either derived from an existing Tibetan base consonant (e.g. Letters 2 and 35 are both derived from the simple Tibetan letter ཁ kha, but are graphically distinct from each other) or from a combination of an existing Tibetan base consonant and the semi-vowel (subjoined) ྭ wa (e.g. Letter 36 is derived from the complex Tibetan letter ཁྭ khwa).
As is the case with Tibetan, these letters have an inherent [a] vowel sound attached to them in non-final positions when no other vowel sign is present (e.g. the letter ꡀ with no attached vowel represents the syllable ka, but with an appended vowel ꡞ i represents the syllable ꡀꡞ ki).
Letters 31-34 and 39 are vowels. Letters 31-34 follow the traditional order of the corresponding Tibetan vowels. Letter 39 represents a vowel quality that does not occur in Tibetan, and may be derived from the Tibetan vowel sign ཻ ai.
Unlike Tibetan, in which vowels signs may not occur in isolation but must always be attached to a base consonant to form a valid syllable, in the ʼPhags-pa script initial vowels other than ꡝ a may occur without a base consonant when they are not the first element in a diphthong (e.g. ue) or a digraph (e.g. eeu and eeo). Thus in Chinese ʼPhags-pa texts the syllables u 吾 wú, on 刓 wán and o 訛 é occur, and in Mongolian ʼPhags-pa texts the words ong qo chas "boats", u su nu (gen.) "water", e du -ee "now" and i hee -een "protection" occur. These are all examples of where 'o, 'u, 'e, 'i etc. would be expected if the Tibetan model had been followed exactly. An exception to this rule is the Mongolian word 'er di nis "jewels", where a single vowel sign is attached to a null base consonant. Note that the letter ꡦ ee is never found in an initial position in any language written in the ʼPhags-pa script (for example, in Tao Zongyi's description of the Old Uighur script, he glosses all instances of Uighur 𐽰 e with the ʼPhags-pa letter ꡦ ee, except for when it is found in the initial position, when he glosses it with the ʼPhags-pa letter ꡠ e instead).
However, initial semi-vowels, diphthongs and digraphs must be attached to the null base consonant 'A (Letter 30). So in Chinese ʼPhags-pa texts the syllables 'wen 元 yuán, 'ue 危 wēi and 'eeu 魚 yú occur; and in Mongolian ʼPhags-pa texts the words 'eeu lu "not" and 'eeog bee.e "gave" occur. As there is no sign for the vowel a, which is implicit in an initial base consonant with no attached vowel sign, then words that start with an a vowel must also use the null base consonant letter ꡝ 'a (e.g. Mongolian 'a mi than "living beings"). In Chinese, and rarely Mongolian, another null base consonant ꡖ -a may be found before initial vowels (see "Letter 23" below).
