Usage
What is a legion? A legion is a large group of people or things, most commonly soldiers, as in World-famous author Stephen King has a legion of fans. Legion can also describe a very large number, as in The number of soccer fans around the world is legion.During the Roman Empire, legion referred to a division of the army that numbered between 3,000 to 6,000 soldiers. As a result, we use legion to refer to a large number of soldiers. However, legion is now used more generally to mean any big group of people or things.Example: The city was filled with legions of fans after the rock star announced they would perform a concert there.
