Wylie transliteration

The Wylie transliteration scheme is a method for transliterating Tibetan script using only the letters available on a typical English language typewriter. It bears the name of Turrell V. Wylie, who described the scheme in an article, A Standard System of Tibetan Transcription, published in 1959. It has subsequently become a standard transliteration scheme in Tibetan studies, especially in the United States.

Any Tibetan language romanization scheme is faced with a dilemma: should it seek to accurately reproduce the sounds of spoken Tibetan, or the spelling of written Tibetan? These differ widely as Tibetan orthography became fixed in the 11th century, while pronunciation continued to evolve, comparable to the English orthography and French orthography, which reflect Late Medieval pronunciation.

Previous transcription schemes sought to split the difference with the result that they achieved neither goal perfectly. Wylie transliteration was designed to precisely transcribe Tibetan script as written, which led to its acceptance in academic and historical studies. It is not intended to represent the pronunciation of Tibetan words.

The Wylie scheme transliterates the Tibetan characters as follows:

In Tibetan script, consonant clusters within a syllable may be represented through the use of prefixed or suffixed letters or by letters superscripted or subscripted to the root letter (forming a "stack"). The Wylie system does not normally distinguish these as in practice no ambiguity is possible under the rules of Tibetan spelling. The exception is the sequence gy-, which may be written either with a prefix g or a subfix y. In the Wylie system, these are distinguished by inserting a period between a prefix g and initial y. E.g. གྱང "wall" is gyang, while གཡང་ "chasm" is g.yang.
