Romanization also may be called Latinization. It represents the written word and/or spoken speech with the Roman/Latin alphabet. It may be attempted if the original words or languages are different from the Roman language and the Latin alphabet. And it may be attempted when there's no writing system at all in effect for the language under consideration. The Romanization/Latinization may be carried out by transcribing the spoken word, or by transliterating the written text. Examples of languages for which Romanization/Latinization is carried out include Arabic, Armenian, Belorussian, Bulgarian, Chinese, Georgian, Greek, Hebrew, Japanese, Korean, Macedonian, Persian, Russian, Thai, Ukrainian, and Vietnamese.
