The Hawaiian language (ʻŌlelo Hawaiʻi) is one of the oldest living languages in the world. The Hawaiian language has had a tumultuous history and was at one point even expected to be extinct by the end of the 20th century. Only about 0.1% of the people who live in Hawaii speak its native tongue today. The Hawaiian alphabet has 13 letters, five vowels (long and short) and eight consonants, one of them being a glottal stop (called ʻokina in Hawaiian).
