rue

What does "rue" mean?
To "rue" something means to feel bitter regret, sorrow, or remorse about a past action or event. Imagine standing over a decision you made long ago, looking back with a heavy heart and wishing you could undo the consequences that have since unfolded. While "regret" is a common, everyday term, "rue" carries a more dramatic, almost poetic weight. It is frequently used in the phrase "rue the day," which emphasizes a deep-seated, lasting sense of despair regarding a specific moment in time. Because of this, it is rarely used in casual, everyday conversation and is more common in literature or formal speech.
