Words are helpful in expressing ideas. So it is no surprise that authors, who sometimes try to express ideas, need to make a few words up. This video from PBS Other Words goes through a few examples.
I’m currently reading The Patterning Instinct by Jeremy Lent. A topic discussed in the book was on how language and culture shape how we think and express ourselves. So the ability to craft out language is an important skill to advance not only language, but also culture and society and potentially the way we think.
Personally, I’m trying to make the word beveragement catch on.
