romanization systems. They can be classified by their characteristics. A particular system’s characteristics may make it better-suited for various, sometimes contradictory applications, including document retrieval, linguistic analysis, easy readability, faithful representation of pronunciation. * Source, or donor language – A system may be tailored to romanize text from a particular language, or a series of languages, or for any language in a particular writing system. A language-specific system typically preserves language features like pronunciation, while the general one may be better for cataloguing international texts. * Target, or receiver language – Most systems are intended for an audience that speaks or reads a particular language. (So-called ''international'' romanization systems for Cyrillic text are based on central-European alphabets like the

This affects the ease of creation, digital storage and transmission, reproduction, and reading of the romanized text. * Reversibility – Whether or not the original can be restored from the converted text. Some reversible systems allow for an irreversible simplified version.


Transliteration

If the romanization attempts to transliterate the original script, the guiding principle is a one-to-one mapping of characters in the source language into the target script, with less emphasis on how the result sounds when pronounced according to the reader's language. For example, the

Transcription


Phonemic

Most romanizations are intended to enable the casual reader who is unfamiliar with the original script to pronounce the source language reasonably accurately. Such romanizations follow the principle of

Trade-offs

For most language pairs, building a usable romanization involves trade-offs between the two extremes. Pure transcriptions are generally not possible, as the source language usually contains sounds and distinctions not found in the target language, but which must be shown for the romanized form to be comprehensible. Furthermore, due to

may vary by a great degree among languages. In modern times the chain of transcription is usually spoken foreign language, written foreign language, written native language, spoken (read) native language. Reducing the number of those processes, i.e. removing one or both steps of writing, usually leads to more accurate oral articulations. In general, outside a limited audience of scholars, romanizations tend to lean more towards transcription. As an example, consider the Japanese martial art 柔術: the Nihon-shiki romanization ''zyûzyutu'' may allow someone who knows Japanese to reconstruct the kana syllables , but most native English speakers, or rather readers, would find it easier to guess the pronunciation from the Hepburn version, ''
