noun
another method; another problem
Used almost exclusively in the fixed expression 余儀なくされる (to be forced to do something) or 余儀ない (unavoidable). The standalone noun meaning 'another method/problem' is rare and mostly found in older or formal writing.
「余儀」という言葉は、現代では「余儀なくされる」という形でよく使われる。
The word 余儀 is commonly used in modern Japanese in the form 余儀なくされる.
彼は余儀なくその申し出を受け入れた。
He was forced to accept the offer.
The exact derivation is uncertain. The kanji 余 (surplus, other) and 儀 (ceremony, matter) suggest a meaning of 'other matter' or 'alternative method', but the word is now fossilized in the phrase 余儀なくされる.
