The definition of the number eleven is a numerical value that represents one more than ten. It is an even number, and in binary it is represented as 1011. Eleven has many uses in mathematics and science, such as being used to represent angles or time measurements. In addition, it can be used to describe the size of something like a group or collection of items.

In some cultures eleven has spiritual significance due to its association with divinity and power; for example, there are 11 traditional Chinese gods who govern over different aspects of life such as wealth or health. Similarly in Christianity there are 11 commandments given by God which Christians must follow if they want to lead moral lives according to their faith’s teachings.

Eleven also appears frequently throughout literature; for instance JRR Tolkien’s Lord Of The Rings trilogy features eleven members on the fellowship questing after Sauron’s ring while Roald Dahl’s Charlie And The Chocolate Factory contains five children plus six adults making up an eleventh person – Willy Wonka himself! As you can see from these examples alone, the number eleven carries great symbolic importance across multiple facets both ancient and modern alike.
