Multilingualism is a skill which involves an individual's ability to speak, read and write in multiple dialects. People who are adept at speaking one language other than their own native language is referred to asbilingual. Not every individual possessing this skill is necessarily fluent in their specified alternative language. While some may be able to speak fluently in a foreign tongue, they may not be able to translate text from that language. In the DC Universe, Multilingualism also includes the ability to understand and converse in alien languages. By example, the inter-galactic bounty hunter Lobo professes that he can speak 17,897 languages, including of course, American English.  In addition, Multilingualism may also include mystical and/or dead languages including the backwards-speak utitilzed by members of the Zatara family.
