磐余

Either from 言はれ (ipare, “that of what is said”), or from a compound of 岩 (ipa, “rock”) +‎ 村 (*are, “village”).[1] The latter theory is more likely as placenames were often formed from compounds of nouns, but a place name formed from a specific conjugation is extremely rare, if at all.

磐余 (Ipare) (kana いはれ)

1. a placename in present-day southern Sakurai, Nara prefecture; site of the ancient Yamato imperial court around the mid-late Kofun period

       Down the river of Patuse [the secluded], a bamboo comes floating—close-jointed, long-jointed; the bottom part making into a lute, the upper part making into a flute. Blowing into [the flute and] playing on [the lute], were I to ascend and stand on the top of Mimorö? and publish it there, the very fishes that pass under the water of the pond of Ipare? [The creeper-clad w]ould come to the surface and lament: the august girdle of small pattern, girded on by our great lord who rules peacefully, hangs down in a knot—not a man is there whoever he may be but would come up and lament.

• Japanese: 磐余 (Iware, in modern dictionaries)

• つのさはふ (tuno₁ sapapu, pillow word alluding to Ipare)
