The word "highball" originated in the United States in the late 19th century and has a dual etymology. It has roots both in the railroad industry and in the world of cocktails.
1. Railroad Etymology:
In early railroading, a "highball" was a signal for a train to proceed at full speed. This terminology originated from the ball-shaped signal or marker that would be hoisted high up on a pole to indicate to the engineer that it was safe to go ahead. Thus, "highball" became associated with a fast or unrestricted movement.
2. Cocktail Etymology:
In the early 20th century, a "highball" also came to refer to a specific type of mixed drink. This cocktail consisted of a spirit, typically whiskey, combined with a carbonated mixer such as soda water or ginger ale.
