Achievement is another word for accomplishment. My greatest achievement to date is the time I won the annual hay-stacking contest at the county fair. That was twenty darn years ago, but I still look back fondly on that moment and the trophy I got to take home.
A noun used to describe something finished successfully or the act of accomplishing, achievement comes from the similarly spelled Middle French achievement “a finishing.” For some people, just being able to make it to work every day on time could be considered an achievement, but the word is usually applied to feats of more heroic proportions. Ralph Waldo Emerson once said, “Every great achievement is the victory of a flaming heart.”
