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

Nihon-shiki Nihon-shiki ( ja, 日本式ローマ字, "Japan-style," romanized as ''Nihonsiki'' in the system itself), is a romanization system for transliterating the Japanese language into the Latin alphabet. Among the major romanization systems for Japan ...

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

phonemic transcription In phonology and linguistics, a phoneme () is a unit of sound that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west ...

and attempt to render the significant sounds (

s) of the original as faithfully as possible in the target language. The popular Hepburn Romanization of Japanese is an example of a transcriptive romanization designed for English speakers.

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.

What is called MR may in many cases be any of a number of systems that differ from each other and from the original MR mostly in whether word endings are separated from the stem by a space, a hyphen or – according to McCune's and Reischauer's system – not at all; and if a hyphen or space is used, whether sound change is reflected in a stem's last and an ending's first consonant letter (e.g. ''pur-i'' vs. ''pul-i''). Although mostly irrelevant when transcribing uninflected words, these aberrations are so widespread that any mention of "McCune-Reischauer romanization" may not necessarily refer to the original system as published in the 1930s. ** There is, for example, the

/ U.S. Library of Congress system, based on MR but with some deviations. Word division is addressed in detail, with a generous use of spaces to separate word endings from stems that is not seen in MR. Syllables of given names are always separated with a hyphen, which is expressly never done by MR. Sound changes are ignored more often than in MR. Distinguishes between ‘ and ’. Several problems with MR led to the development of the newer systems: *

(1942): This system has become the established standard romanization for Korean among linguists. Vowel length in old or dialectal pronunciation is indicated by a macron. In cases that would otherwise be ambiguous, orthographic syllable boundaries are indicated with a period. This system also indicates consonants that have disappeared from a word's South Korean orthography and standard pronunciation. *

RR is generally similar to MR, but uses no diacritics or apostrophes, and uses distinct letters for ㅌ/ㄷ (t/d), ㅋ/ㄱ (k/g), ㅊ/ㅈ (ch/j) and ㅍ/ㅂ (p/b). In cases of ambiguity, orthographic syllable boundaries were intended to be indicated with a
