Words and labels meanings. What you give something a label, you label it according to what it is or what it does. For example, a tool that is used to drive screws into wood is called a "screwdriver". In another example, in years long ago a person who made pottery was called a potter.
However, when something is personafied, then the meaning is often disregarded. Let us take a look at the word "Spirit". Putting any form of personification aside, let's look at what the word actually means.
