まじきLiterary condemnation before a noun
まじき is a literary form placed before a noun to condemn an action as something that should never be done, allowed, or repeated.
What the phrase judges
まじき modifies the noun immediately after it. That noun usually names an act, statement, mistake, offense, tragedy, or similar matter that the writer strongly rejects. Depending on the noun and context, natural English may use “must never,” “should never,” “unforgivable,” or “unworthy of.”
Typical condemnatory readings
Translate the judgment, not just the form
A mechanical translation such as “must not” does not always fit the English sentence. With a noun meaning “act,” the phrase may be best rendered as “an unforgivable act”; with a lesson or tragedy, “never to be forgotten” or “never to be repeated” may be more natural. In every case on this page, the central idea is strong condemnation or exclusion.
