Did You Know?

Pinnacle is one of several words that aspire to both literal and figurative heights. Others include summit, peak, climax, apex, acme, and culmination. All of these can refer to the highest point of a mountain or structure, or the highest point attained or attainable over a person's lifetime, career, etc. When referring to part of a building, pinnacle describes a projection on top of a tower (as on a Gothic cathedral). The word derives via Anglo-French from Late Latin pinnaculum, meaning "small wing," a diminutive of pinna, meaning "wing or battlement." When used figuratively, pinnacle sometimes implies a dizzying and insecure height, such as that brought on by unexpected fame.
