deeply disappointed; utterly mortified; extremely vexed
A yojijukugo expressing intense regret, chagrin, or mortification. Often used in formal or literary contexts to describe a state of profound emotional distress over an outcome.
He felt utterly mortified by his own mistake.
無念千万、試合に負けてしまった。
To my deep regret, I lost the match.
残念 is a common, everyday word for 'disappointing' or 'regrettable'. 無念千万 is much stronger and more literary, implying deep mortification or vexation.
無念 alone means 'regret' or 'chagrin'. 無念千万 intensifies this feeling, adding the sense of 'extremely' or 'utterly'.
A yojijukugo combining 無念 (regret, chagrin) with 千万 (extremely, myriad). The exact historical derivation is uncertain, but the phrase is conventionally used to express profound disappointment.
