<Seven interesting facts about languages>
1. The United States of America does not have an official language. I know what you are thinking: "What? Where did English go?" But in fact, the US does not have any official language since they are a salad bowl country with so many different people with diverse backgrounds living altogether. Furthermore, with all the Native American languages and dialects, more than 300-450 languages are spoken in the US.
2. According to the Guinness World Records, the most translated document on Earth is... a six paged document called the Universal Declaration of Human Rights (UDHR)! The UDHR has been translated into 370 languages and dialects from Abkhaz to Zulu as of 2009. When we narrow the question down a bit to 'the most translated BOOK', of course the Bible takes the crown.
3. Guess where the country with the most incredible linguistic diversity is? It is Papua New Guinea! This country with just 7.6 million people has more than 850 languages. The oldest group of them are called the 'Papuans', but despite its name they do not share a same root.
P. S. When we say the languages 'share the root', it means that they are from the common starting point. For example, Swedish, Norwegian, and Danish speakers can communicate with each other even though they continue speaking with their own mother tongue because the three languages have many similarities. This phenomenon also takes place when Portuguese, Spanish, and Italian nationals have a conversation.
4. Another interesting fact from Papua New Guinea! The Rotokas language spoken by about 4000 people on the island of Bougainville has twelve letters, representing eleven phonemes: just eleven! The Rotokas language also does not have any diacritics--glyphs added to a letter (such as á and í in Spanish)--and ligatures--where two or more graphemes or letters are joined to form a single glyph (such as encyclop"æ"dia).
5. Do you know what is a 'Basque' language? Spoken by people living in the mountain region between France and Spain (the north of Spain), Basque is one of the most isolated languages on Earth. As a result of this geographical position, Basque remains as the only language in the world that has zero correlation to any other language.
6. Guess which country has the most official languages. Spain? Switzerland? Actually, South Africa holds this record: thanks to its incredible level of diversity, there are eleven official languages actively spoken in South Africa. This is amazing, of course, but I cannot stop myself from thinking about the workload of governmental workers who have to publish the official documents in eleven different versions.
7. The shortest grammatically correct sentence in the world exists in English: Go! Yes, no other sentences in any other languages can beat this record. Even without an explicit subject of the sentence, we all can understand this beautiful sentence :D
