taru-adjective, adverb taking the 'to' particle
Literary, somewhat archaic word describing something in a state of absolute purity, without any mixture or flaw. Often used adverbially with と (e.g., 醇乎と) to modify a verb or adjective.
His art is pure and without a single blemish.
その酒は醇乎たる味わいで、雑味がまったくなかった。
The sake had a pure, unadulterated flavor with no off-tastes at all.
Literary kanji form; 醇 suggests pure, unadulterated quality. Rare in modern writing.
Alternate literary kanji form using 純 (pure). Also rare.
From 醇 “pure; unmixed” and the Classical Chinese particle 乎. In Japanese it occurs in the literary adjectival construction 醇乎たり or 醇乎として.
