Linguists have compared the many translations and even editions of the same translation for style, composition, titles, wordings and genealogy. As an example: as of 2011 there are approximately 47 translated editions of "The Little Prince" in Korean, and there are also about 50 different translated editions in Chinese (produced in both mainland China and Taiwan). Many of them are titled "Prince From a Star", while others carry the book title that is a direct translation of "The Little Prince". By studying the use of word phrasings, nouns, mistranslations and other content in newer editions, linguists can identify the source material for each version: whether it was derived from the original French typescript, or from its first translation into English by Katherine Woods, or from a number of adapted sources.
