A score of years refers to 20 years. The term “score” originates from an old counting system used in English, where “score” meant a group of 20. This method of counting was common in historical and literary contexts, making appearances in iconic speeches like Abraham Lincoln’s Gettysburg Address: “Four score and seven years ago…” Here, “four score” translates to 80 years. While the word isn’t as widely used today, it still pops up in literature, historical discussions, and idiomatic expressions. Understanding this term connects us to a rich linguistic tradition and adds a touch of poetic flair to our language.
