Words

The first thing is the recognizable elements that appear in an image. If we see a glass drawn, we will have information that will be a noun. We could consider it a word. We can have complements to that word. If it is made of glass, we provide a complement of information.

In the case of characters, we can have common names and proper names. If we draw a recognizable silhouette of a human figure, without further detail, we will get a common name. If, on the other hand, we give that figure enough details to be recognizable, it will become a proper name.

If that figure executes an action, we will have a verb.

This would be a simplification to understand that an image can have something like words and phrases.
