This languages trivia quiz has 50 free questions with answers and covers the world's tongues from every angle: which has the most speakers and which the most native speakers, how many languages exist and how fast they are dying, the country with 840 of them and the ones with 16 or 37 official languages. It takes in scripts and alphabets (cuneiform, the Rosetta Stone, Cyrillic, Hangul, the Cherokee syllabary, Braille, the 12-letter Rotokas alphabet), the oddities (Basque with no relatives, Icelandic that has barely changed in 800 years, the whistled Spanish of La Gomera, the click-heavy Taa of Botswana) and the invented ones, from Esperanto to Klingon. The easy questions ask which language has the most speakers, how many tones Mandarin has and what Duolingo's mascot is. The medium ones cover the UN's six languages, Switzerland's four, India's 22 and who revived Hebrew. The hard ones want the year Sequoyah finished his syllabary, how far a Gomeran whistle carries and which country beats Zimbabwe for official languages. Every answer has been checked against a reference encyclopaedia, and each question shows its explanation and citation once you have answered.
