The word "jaded" describes a feeling of weariness or a lack of enthusiasm that comes from having too much of something, particularly experiences or activities that once brought joy or excitement. When someone feels jaded, they may be disillusioned or tired, often due to the monotony or excess they've encountered.
The word "jaded" comes from the late Middle English term "jadede," which is derived from the Spanish word "jaca" meaning "mare." The original sense referred to a worn-out or tired horse, reflecting the idea of being overused or exhausted.
