International Linguistics Olympiad
IOL 13 was held from July 20 to 24, 2015, at the American University in Bulgaria, Blagoevgrad, Bulgaria. Chaired by Aleksandar Velinov, it received 43 teams from 29 countries, with Bangladesh, France and Kazakhstan sending teams for the first time. The Problem Committee was chaired by Bozhidar Bozhinov. The five problems at the individual contest were about Nahuatl (Uto-Aztecan) and Arammba (South-Central Papuan) numbers, morphology in the Besleney dialect of Kabardian (Abkhaz-Adyghe), Soundex, Wambaya (West Barkly) syntax and the rules of Somali (Afroasiatic) poetry. The team problem involved using extracts from a monolingual Northern Sotho (Bantu) dictionary to build a grammar and lexicon of the language.
