Imo ga atari waga sode furamu ko no ma yori idekuru tsuki ni kumo na tanabiki

妹があたり我が袖振らむ木の間より
出で来る月に雲なたなびき

Roma-ji: Imo ga atari waga sode furamu ko no ma yori idekuru tsuki ni kumo na tanabiki
English Translation: Toward my love's home
I will wave my sleeves to her;
O clouds, do not trail
across the moon that rises,
coming out between the trees
Meaning: I will wave my sleeves toward where my love lives—clouds, do not trail across the moon now rising between the trees.
Commentary: Book Seven Miscellaneous Poems 1085

Headnote continued from the preceding poem: "On the Moon"
The poet means to wave his sleeves toward his beloved's house and asks the clouds not to hide the moon rising between the trees, so that his gesture may be seen. Waving the sleeves was a gesture with magical power to convey one's feelings to someone far away.
Within the group on the moon, the moonlight is treated as a helper that lets the lovers' hearts reach each other. The poet is unknown.

The first line, "Toward my love's home," means toward the neighborhood of his wife's house.
In the second line, "I will wave my sleeves to her," "mu" expresses intention. Sleeve waving was a gesture conveying the pain of parting or longing, and the poem pauses here.
The third line, "coming out between the trees," depicts the moon rising through the trees.
The fourth line refers to the moon emerging from between the trees.
The final line, "O clouds, do not trail," is a prohibition formed by placing the adverb "na" before the continuative form of the verb: clouds, do not drift across it.
