蝦夷方言藻汐草

The radio textbook explicitly writes nisor an and glosses it 晴れる, supporting the separated modern reading for 日和. Its cover dates the volume January–March 2000; the corpus labels it 1999 from the fiscal-year series. Another nisor an corpus example merely says the sky exists. NINJAL 043#6 gives nisoro an with a questioned cloudy gloss, so that vowel-preserving variant cannot be treated as unambiguous fair-weather evidence. The earlier apostrophe spelling is retained as a comparison, not a probability claim.
