Etymology

Borrowed from French disquisition (“disquisition”), from Latin disquīsītiō (“inquiry, investigation”), from disquīrō (“to investigate”) (from dis- (prefix meaning ‘apart, asunder’) + quaerō (“to look for, seek; to inquire, question”)) + -tiō (suffix forming nouns relating to an action or the result of an action).
