1. In the alphabetization of SENĆOŦEN, glottal stop and laryngealization of sonorants are traditionally ignored.
2. Note that [ʧ] (/č/ ⟨Ć⟩) is not equivalent to [tʃ] (/tš/ ⟨TŚ⟩) in SENĆOŦEN.
3. There are some idiosyncrasies in the SENĆOŦEN writing system that have become conventionally accepted. For example, /ʔə́y̕ / ‘good’ is spelled ÍY¸, /sčéenəxʷ/ ‘salmon’ is often spelled SĆÁNEW̱ or SĆȺNEW̱. Other long vowels are treated similarly.
