This alphabet was created by American missionaries in the early 19th century. Before this, Hawaiians did not have a written language. The missionaries used to letters from the English alphabet to represent Hawaiian sounds, and they added two letters: `ʻ` (okina) and `ō` (kahakō).
The okina is used to represent the glottal stop, a sound that is made by closing the vocal cords. The kahakō is used to indicate a long vowel.
