アイヌ (transliteration needed) (Latin spelling aynu)
- a person, a human being
- the Ainu people
- father, husband, or other adult male
- ku koro aynu
- my father
This spelling is more common than アィヌ.
The Ainu pronunciation of this term has only two morae, so academic materials may spell this term in kana with the small ィ, or in romaji with a y, to explicitly indicate that the initial vowel is the single-mora diphthong ay (/ai̯/), and not the two-mora diphthong a i (/a.i/).
However, there is no three-mora term a i nu in the Ainu language, and most Ainu texts written in katakana use this spelling instead.
