Panegyric

A panegyric is a laudatory speech or literary work praising someone or something; originally, in antiquity, it was a solemn public address delivered before an assembly, and since the 19th century the term has more often been used ironically to mean excessive, unwarranted praise or flattery. It may refer both to a genre (classical rhetoric, court poetry) and to a rhetorical device, with synonyms such as “praise,” “ode,” “dithyramb,” and “akathist.”
