At Pizzadelique after ceramics this week we were talking about words that were invented by writers which are such common usage now that it's surprising they weren't always in usage. Specifically that Lewis Carroll invented the word chortle - a combination of chuckle and snort. This is a word that just sounds like a word from old English. Googling (first used July 1998, added to OED June 2006) this I came across a no-longer updating blog, Heredotus Wept, that had posted about this.
Words invented by Milton
Words invented by Shakespeare
Words that Shakespeare invented
What did we used to call eyeballs before Shakespeare coined the term, when we undressed did we have to say "I am taking my clothes off or was it unrobe or something"? And were ladybirds just red beetles with black spots?
Without Milton nothing could be terrific, and there would be no fragrance.
It's the glory of language. Love it.
