蝦夷方言藻汐草

Nisat is well documented for daybreak, while 朝 can cover a broader morning period. The word fits the beginning of the morning, with that difference in scope kept explicit. Kunneywa is a separate morning comparison whose sounds differ; peker nisat adds a dawn-light modifier. Nisat’s occurrence under 暁 on the preceding line corroborates the local association with dawn but supplies no independent witness.
