Use or misuse of a word tells us nothing about what the word allegedly describes.
We don't learn about the center of the galaxy by looking something up in a dictionary. You learn by using a telescope.
What is this obsession about definitions? A word is a human artifact, it tells us nothing except someone has devised it as a description of a thing or action. It is purely subjective. Even if we all agree on a definition, that is no guarantee the definition tells us anything about the object or action or property we are discussing.
Think about it. You don't learn what "love" is by looking it up in a dictionary. In fact, if you have to look it up then you obviously don't know what you're talking about, and the definition(s) in the dictionary entry will do you no good at all.
