What ē means
It marks vowel length. Māori can use long vowels to distinguish words. Latvian has two e sounds; ē marks length, while the word determines the sound.
Why is Māori sometimes written Maaori?
Type and computer limits led to variants.
The Latin spelling taught by early missionaries left Māori vowel length unmarked; Williams’s Māori dictionary first showed macrons in its fifth edition, in 1917.
Printing and computer limits encouraged unmarked (Maori), doubled (Maaori), and umlauted (Mäori) forms; macrons were widely supported online by the early 2000s.
