The romanization or Latinization of Ukrainian is the representation of the Ukrainian language using Latin letters. Ukrainian is natively written in its own Ukrainian alphabet, which is based on the Cyrillic script.
Romanization may be employed to represent Ukrainian text or pronunciation for non-Ukrainian readers, on computer systems that cannot reproduce Cyrillic characters, or for typists who are not familiar with the Ukrainian keyboard layout. Methods of romanization include transliteration, representing written text, and transcription, representing the spoken word.
In contrast to romanization, there have been several historical proposals for a native Ukrainian Latin alphabet, usually based on those used by West Slavic languages, but none has caught on.
Transliteration is the letter-for-letter representation of text using another writing system. Rudnyckyj classified transliteration systems into the scholarly system, used in academic and especially linguistic works, and practical systems, used in administration, journalism, in the postal system, in schools, etc. The scholarly or scientific system is used internationally, with very little variation, while the various practical methods of transliteration are adapted to the orthographical conventions of other languages, like English, French, German, etc.
Depending on the purpose of the transliteration it may be necessary to be able to reconstruct the original text, or it may be preferable to have a transliteration which sounds like the original language when read aloud.
Transcription is the representation of the spoken word. Phonological, or phonemic, transcription represents the phonemes, or meaningful sounds of a language, and is useful to describe the general pronunciation of a word. Phonetic transcription represents every single sound, or phone, and can be used to compare different dialects of a language. Both methods can use the same sets of symbols, but linguists usually denote phonemic transcriptions by enclosing them in slashes / ... /, while phonetic transcriptions are enclosed in square brackets [ ... ].
