jeremiad

Jeremiad, derived from the biblical prophet Jeremiah known for his laments, refers to a lengthy, cautionary, or pessimistic rant. It can also denote a prolonged expression of deep sadness or sorrow. Jeremiah's prophecies and lamentations have influenced the usage of "jeremiad" to describe someone who constantly expresses pessimism or "carries on." The word was initially borrowed into French as "jérémiade" and later adopted into English. Today, "jeremiad" encompasses both angry rants and sorrowful lamentations.
