秋しゅう暑しょ

noun

lingering summer heat in autumn

Rare literary term for the residual heat felt in early autumn. In everyday language, expressions like 残暑 (ざんしょ) are far more common.

• 秋しゅう暑しょの候こう、皆みな様さまにはますますご清せい栄えいのこととお慶よろこび申もうし上あげます。

  In this season of lingering autumn heat, I hope you are all in good health and spirits.
