Quotes From "The Etymologicon: A Circular Stroll Through The Hidden Connections Of The English Language" By Mark Forsyth

1
If Jupiter was in the ascendant when you were born, you are of a jovial disposition; and if you're not jovial but miserable and saturnine that's a disaster, because a disaster is a dis-astro, or misplaced planet. Disaster is Latin for ill-starred. The fault, as Shakespeare put it, is not in our stars; but the language is. Mark Forsyth
2
Pot itself has nothing to do with pots and pans, but comes from the Mexican-Spanish word potiguaya, which means marijuana leaves. And marijuana is a Mexification of 'Mary Jane' for reasons that everybody is much too stoned to remember. Mark Forsyth

A bar, as any good dictionary will tell you, is a rod of wood or iron that can be used to fasten a gate. From this came the idea of a bar as any let or hindrance that can stop you going where you want to; specifically the bar in a pub or tavern is the bar-rier behind which is stored all the lovely intoxicating liquors that only the bar-man is allowed to lay is hands on without forking out. Mark Forsyth

The Latin word for sausage was botulus, from which English gets two words. One of them is the lovely botuliform, which means sausage-shaped and is a more useful word than you might think. The other word is botulism. Sausages may taste lovely, but it's usually best not to ask what's actually in them. Curiosity may have killed the cat, but it was a sausage-maker who disposed of the body. Mark Forsyth
