A literary and formal verb expressing a decisive judgment. More authoritative than 判断(はんだん)する and often used in legal, academic, and journalistic writing. The ずる conjugation is classical and gives the word a formal, weighty tone.

CONJUGATION NOTE:
Conjugates as a ずる verb (サ変(さへん) variant): (だん)ずる → (だん)じる (more common modern form) → (だん)じて (te-form, also used as an emphatic adverb meaning "absolutely").
