A stiff, literary pattern used in editorials, news commentary, formal speeches and official criticism. It condemns behaviour as incompatible with a person's role or status, such as officials, teachers or professionals. Unlike たる, which describes the ideal a status demands, まじき labels a concrete act as a violation of that ideal.
Learners sometimes end a sentence with まじき; it is attributive and must directly modify a noun such as 行為 or 発言.
Do not use まじき in casual conversation or for trivial matters; it carries strong moral condemnation.
Note that the frame is usually Nにあるまじき, not Nであるまじき, when referring to someone's position.
- たるもの / たるN1「たるもの」speaks positively, meaning 'as a..., one should...', and is followed by expressions like 「べきだ」; 「まじき」condemns from the negative side behavior one should not have, works only as a modifier, and can attach to verbs with no restriction to status. Their directions are opposite, so they cannot be swapped.
- てはならないN2「てはならない」mainly functions as a predicate expressing prohibition or admonition and can be used in rules and laws; 「まじき」usually works only as a modifier and carries a stronger moral condemnation. 「あってはならない事態」can be rephrased as 「あるまじき事態」, which sounds even heavier.
- べからずN1「べからず」mainly issues a direct prohibition at the end of a sentence and is often seen on signs and in regulations; as a modifier it must change to 「べからざる」or 「べからぬ」, where its meaning is close to 「まじき」, but for condemning behavior unbecoming of one's status, 「にあるまじき」is generally used.
- にもほどがあるN1「にもほどがある」is colloquial, saying that behavior or a state 'has gone too far'; it attaches to nouns, adjectives, and plain verb forms, usually comes at the end of a sentence, and can also be used as hyperbolic praise. 「まじき」is a written moral condemnation that modifies nouns, so the two are generally not interchangeable.
- ものではないN2「ものではない」is similar to 「まじき」only in the sense of 'should not': it advises based on common sense with a relatively mild tone and neutral register, usually ending the sentence directly; 「まじき」is written style, harshly condemnatory, and modifies nouns. 「ものではない」also has the meaning of 'impossible'.
「たる/たるもの」states positively how someone in a certain role should behave, while 「まじき」condemns from the negative side behavior that should not exist; 「てはならない」and 「べからず」are direct prohibitions, with 「べからず」often seen on signs; 「ものではない」is general advice based on social common sense; and 「にもほどがある」criticizes going too far, not the behavior itself being unacceptable.
