also: しんちょう
na-adjective
profound; deep; weighty; serious
Describes something deeply meaningful, emotionally heavy, or of great significance. Often used for feelings, words, or situations that carry weight beyond the surface. The reading じんじゅう is standard; しんちょう is rare and literary.
彼の言葉には深重な意味が込められていた。
His words carried a profound meaning.
深重な責任を感じる。
I feel a weighty responsibility.
The exact derivation is uncertain. The kanji 深 (deep) and 重 (heavy) combine to suggest profound weightiness. The reading じんじゅう is likely a sound shift from しんちょう, but the historical development is unclear.
