Koto furaba sode sae nurete tōrubeku furinamu yuki no sora ni ketsutsu

English Translation
If it's going to fall,
let it drench my sleeves as well,
soaking through and through—
but the snow that would come down
keeps on melting in the sky.
Meaning
If it is going to fall, it should fall enough to soak even my sleeves through—yet the snow keeps melting away in the sky.
Commentary
Book Ten Winter Miscellaneous Poems 2317

Headnote continued from the preceding poem: "On Snow"
This poem regrets that the snow, which should fall enough to soak through the sleeves if it falls at all, keeps melting in the air. It shows both longing for a real snowscape and frustration at snow that will not fully fall. Against the lingering snow of the preceding poem, this one sings of snow vanishing in the sky, a contrast of snow that melts and snow that remains.

In the first line, "koto furaba," "koto" means if at all: if it is going to fall.
In the second line, "sode sae nurete," "sae" expresses addition: even the sleeves wet.
The third line, "so as to soak through," names the degree.
In the fourth line, "furinamu yuki no," "na" is emphatic and "mu" conjecture: the snow that would fall.
In the last line, "sora ni ketsutsu," "ke" means to vanish and "tsutsu" marks repetition: melting away in the sky.
