expression, godan verb (-ru)
offer a toast for longevity
Archaic ceremonial expression used to present a toast wishing someone long life. Not used in modern everyday speech.
古い文献では、宴の席で「寿を上る」と記されていることがある。
In old documents, it is sometimes written that they 'offer a toast for longevity' at banquets.
The phrase combines 寿 (longevity) with the archaic honorific verb 上る (to offer humbly). The exact historical derivation is uncertain, but it appears in classical texts as a set expression for toasting.
