it must be spilling over.

Commentary
Book Seven Names of Things 395

Headnote: "Owarikome (Owari rice)"
The poet reasons that since the pond is brimming with so much water, it must be overflowing from the mouth of the sluice. Reasoning about the scene of an overflowing pond, the poem hides the name of Owari rice given in the headnote in the run of sounds "o hari kome" from the first to the second line. The headnote names the thing hidden in the poem.
The author, written as Sukemi, is Fujiwara no Sukemi. A son of Fujiwara no Hirotsune, he was a mid-Heian poet known as Tōroku. He excelled at poems hiding the names of things, and his personal collection is the Tōrokushū.

First line, "ike o hari," means "filling the pond." With "kome" at the start of the second line, it hides the name "owarikome."
Second line, "kometaru mizu no," means "the water filled in." Following the persimmon of the preceding poem, the name of a food is sung of.
Third line, "ōkareba," means "since there is so much," the perfective form with "ba" expressing a reason.
Fourth line, "ii no kuchi yori," means "from the mouth of the sluice."
Final line, "amaru naru beshi," means "it must be overflowing," with "naru" assertive and "beshi" conjectural.
