A story made from Captcha words. Read on a video.
The meaning is drawn from context, which includes everything from spelling and grammar to plot, tone of voice of the reader and the similarity of nonsense words to actual words that have meaning collectively which we have taken in as we learned language. The latter is a function of our ability to connect, compare and categorize. Memory plays a significant role too. Complicated cognitive stuff going on here.
We are a species that likes to endow the meaningless with meaning.
