露は袖に物思ふころはさぞな置く
かならず秋のならひならねど
Roma-ji

Tsuyu wa sode ni mono omou koro wa sazo na oku kanarazu aki no narai naranedo

English Translation
On sleeves, the dew falls
when one is lost in brooding,
surely it settles,
though it need not be the way
of autumn alone to fall
Meaning
When one is lost in sorrowful thought, the dew surely settles on one's sleeves—though that is not necessarily a custom of autumn alone.
Commentary
Book Five Autumn Poems II 470

Headnote: "Among autumn poems."
This is the tenth poem of the dew sequence. In times of sorrowful brooding, dew surely settles on the sleeves—though that is not necessarily a custom of autumn. According to the headnote, it is one of a group of autumn poems.
The author was a son of Emperor Takakura who ruled as retired emperor after abdicating, established the Poetry Office, and ordered the compilation of the Shinkokinshū. Defeated in the Jōkyū War, he was exiled to the Oki Islands.
The scene is a time of brooding, on sleeves where dew settles.
The direct occasion was the composition of autumn poems, though the headnote records neither the setting nor the year.

The first line, "tsuyu wa sode ni," is hypermetric with six syllables and fixes the dew's resting place as the sleeves rather than the grasses.
In the second line, "wa" singles out "in times of brooding," limiting the time.
In the third line, "sazo na" means "surely," strongly affirming that dew settles on the sleeves. The poem breaks here.
The fourth line, together with "naranedo" in the last line, means "not necessarily of autumn."
In the last line, "narai" is custom and "do" a concessive particle; by inversion it attaches to the third line. Against the convention that dew belongs to autumn, the poem argues that dew on the sleeves, as tears of sorrow, knows no season. Taking up 469, which asked whether dew learned from brooding sleeves, it answers with the word "narai" and separates dew on the sleeves from the customs of autumn.
