Hallmark

A “hallmark” is a distinctive characteristic of something or someone. The smell of freshly-cut grass, decorative bunting, flyovers, the national anthem, bright sunshine, optimism, and excitement for the years to come: these are the “hallmarks,” or distinctive characteristics, of Opening Day, the first day of the baseball season. Elvis Presley’s hip swivel was a “hallmark” of his performances. The CEO said exercising and eating breakfast every morning are “hallmarks” of her success.
