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 as bilingual. 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. In addition, Multilingualism may also include mystical and/or dead languages including the backwards-speak utitilzed by members of the Zatara family.
Both Captain Marvel and Black Adam are multilingual.
