gruel

What does "gruel" mean?
Gruel is a thin, watery porridge made by boiling grain—usually oatmeal, wheat, or rice—in water or milk. Historically, it was considered a humble, inexpensive food associated with poverty or institutional settings like workhouses, where it was served to provide basic sustenance with little flavor. In modern usage, the word has taken on a figurative meaning related to something tedious, monotonous, or physically exhausting. When someone describes a task as "grueling," they are invoking the image of this thin, flavorless, and repetitive substance to emphasize how draining or unrewarding an experience feels.
