For example, you and I indirectly, implicitly agree that the thinking form "tree" refers to the thinking form of an image of a tree. However, we don't sit at a table and go over the entire lexicon before entering into conversation. Rather through countless usage of the thinking form "tree" and its use to refer to the thinking form of an image of a tree, we have all come to agree upon the thinking form and its usage simply by using it ourselves.
More interesting, however, is the idea that language is a purely mental activity. Language, according to De Saussure, is used to order amorphous blobs in our minds into more coherent blobs. Thus, the word "tree" doesn't refer directly to a tree or the trees. Instead, the word tree, itself a purely "fictitious" entity in that it and its relevance exists only in our English-speaking minds, refers to what we believe a tree to be. In imagery, this would show up as the word "tree" with the equals symbol followed by a thought bubble of a tree, not an image of a tree. This is an important distinction to make because language cannot directly affect reality, merely alter perspective of reality. Action, ultimately, is the thing that affects reality and action is always interpreted in the mind through language.
