What is a "birdie"?

A "birdie" in golf refers to achieving a score of one stroke less than the par value for a particular hole, commonly achieved by sinking the ball into the hole with one fewer stroke than expected. The term "birdie" is believed to have originated in the early 20th century in the United States. There are a few theories about its origin, but the most widely accepted one suggests that it stems from an American slang term used to denote something excellent or outstanding, akin to "bird" meaning something desirable or attractive. Thus, when a golfer scored one stroke less than expected, it was considered a particularly good outcome, and the term "birdie" came to represent this achievement. Today, "birdie" remains a staple term in golf scoring, signifying a successful and favorable shot on the course.
