I made three new metaphors; encyclopedia, white bear, and the sun.
An encyclopedia means a person who has a wide knowledge of many things. We can use this word when we praise the speaker’s knowledge.
A white bear means the people who has white skin and big body. It includes the meaning of the power of a bear.
The sun means the people who have passion and enthusiasm. In addition, the people who has beautiful smile or popular person are also called the sun.
