in autumn above all seasons
shine with a brighter glow?

Commentary
Book Three Autumn Poems 95

Headnote: "Topic unknown"
The author is listed here as an unnumbered poet, but the Shikashu attributes the poem to the Minister of the Right, Minamoto no Masasada.
The moon hangs in the same sky all year, so why does it look so much brighter only in autumn? The poem praises the beauty of the autumn moon by asking for the reason, and shares this question with the next poem.

The first line, "ika nareba," asks "for what reason," answered by ramu in the last line. It is the same opening as 87 in this book.
The second line, "onaji sora naru," means "in the same sky" through all four seasons.
The third line, "tsukikage no," is the light of the moon, kage meaning light.
The fourth line, "aki shimo koto ni," means "in autumn especially," shimo being an emphatic particle.
The last line, "terimasaruramu," asks why it shines brighter. The next poem, 96, has the same last line, and the two form a pair asking about the brightness of the autumn moon.
