I know what it is and how to write it, but what exactly makes the language dense? There are words strewn across the page just like any other book, and most of the dense stuff I'm reading doesn't employ any bigger words than Harry Potter, so why is it slower and more difficult to read? I just read the first page of Gravity's Rainbow and the words are easy to read and the sentences are short, but it's thick like syrup. Is there some sort of concrete answer to how this thickness develops? Another question. Is there a difference between rich and dense?
