The beauty of language is not that it communicates meaning, but that each word provides a bank for every human to deposit their experiences. The words swell with us, collecting our connotations. So that one word is a saga in itself: said, read, sung, heard and added to the art in your mind’s deposit account specifically for that one word.
Even literary nonsense is a language art. Because even if the sentence makes no mathematical sense, novel combinations and original juxtapositions still deliver emotion to the reader.
