seshiとは 意味・読み方・使い方

Within the poem, "Hana no iro ha utsurinikerina itazurani wagami 'yonifuru nagame' seshi mani," the "yonifuru nagame" is interpreted twice. One interpretation is "the long spell of rain in the evening" and the other is "pass the time in the world (while) watching," which lets the poem carry both meanings as: "The color of the cherry blossoms has faded, and I have vainly passed the time in the world while watching the rain falling."発音を聞く 例文帳に追加
