How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
cover, lid, cap
Futa is spelled 蓋上山 for Mount Futagami in the Man'yōshū of circa 759, from Proto-Japonic *pota.
