Koiwabite omoi irusa no yama no ha ni izuru tsukihi no tsumorinuru kana - Kinyo Wakashu(English Translation & Meaning)

恋ひわびて思ひいるさの山の端に
出づる月日の積もりぬるかな

Roma-ji: Koiwabite omoi irusa no yama no ha ni izuru tsukihi no tsumorinuru kana
English Translation: Pining with my love,
sunk in thought at Irusa's
mountain rim, from where
the moon and sun come rising,
the months and days have piled up
Meaning: Pining with love and sunk deep in thought, I have watched the months and days pile up, like the moon and sun rising over the rim of Mount Irusa.
Commentary: Book Seven Love Poems I 414

While the poet pined and sank deep into brooding, the months and days piled up in vain, like the moon and sun rising and setting over the rim of Mount Irusa. With irusa meaning both sinking into thought and Mount Irusa, the poem lays the length of time passing in love over the coming and going of moon and sun.
Some manuscripts name Ōnakatomi no Kinnaga as the author and give the headnote 'Composed on love likened to a mountain.' It would then be a poem on that topic.
Poems 369 and 371 in this book also sing of the moon in connection with love.

First line, 'koiwabite', means pining with love. It is the same as the first line of poem 375 in this book.
Second line, 'omoi irusa no', is a pivot word in which irusa means both iru, sinking into thought, and Irusa, a poetic mountain in Tajima, left in kana.
Third line, 'yama no ha ni', means on the mountain's rim.
Fourth line, 'izuru tsukihi no', means of the moon and sun that rise, layering the rising moon and sun over the passing years. Iru, to enter, in the second line and izuru, to come out, form a pair.
Final line, 'tsumorinuru kana', means they have piled up, the perfective nu joined to the particle kana.
