noun, noun which may take the genitive case particle 'no'
Used in compounds like 意義 (significance) or 定義 (definition). Rarely used alone in modern Japanese; the standalone sense is mostly literary or formal.
この言葉の義を調べる。
I look up the meaning of this word.
non-blood relationship; in-law
Used as a prefix in family terms to indicate a relationship by marriage, not by blood, e.g., 義父 (father-in-law), 義理の兄 (brother-in-law).
義理の母はとても優しい。
My mother-in-law is very kind.
prosthesis; artificial body part
Used as a prefix in medical/technical terms for artificial body parts, e.g., 義手 (artificial hand), 義足 (artificial leg).
事故で足を失い、義足を使っている。
He lost his leg in an accident and uses a prosthetic leg.
He is a man who values honor above all else.
正義と義の違いを考える。
I think about the difference between justice and righteousness.
彼女は義に厚い人として知られている。
She is known as someone who is deeply loyal and honorable.
He served his lord with unwavering loyalty.
He stuck to his principles no matter the situation.
意義 means significance or meaning and is commonly used alone, while 義 in this sense is rare outside compounds and feels literary.
義務 names a concrete duty or obligation (often legal or social), whereas 義 is the underlying sense of moral rightness that such duties spring from.
不義 denotes immorality or unfaithfulness, the direct opposite of the righteous, dutiful sense of 義.
議 (discussion, deliberation) shares the same reading ぎ as 義 but refers to debate or argument, not morality or meaning.
儀 (ceremony, ritual) is another same-sounding character often confused with 義, but it refers to formal rites, not morality or in-law relations.
