Once again it's time for me to give you some true information to put in place of the misinformation you might have had before, so here goes!
The word sardine has been used in English ever since the early 15th century. It might have come from the Mediterranean island of Sardinia, where there used to be tons of little pilchards for fishermen to catch.
Sardines are very healthy for you to eat because they have good oils and vitamins and stuff to make your coat all shiny and nice. Also they might keep you from getting heart attacks. But if you have high blood pressure, then you maybe shouldn't eat sardines because they are preserved with a lot of salt.
In the U.S., people usually eat canned sardines, but in the Mediterranean, people also grill them or smoke them. I think Mom should buy some sardines for us dogs and cats to eat because we would really, really like them, and they would be good for us, too. Next time Mom isn't looking, I am going to write "sardines" on the grocery list!
So anyway, a bellwether is a leader, like the ram is the leader of the flock. But people use bellwether nowadays to mean more like a predictor or harbinger, instead of what the word used to mean. So for example, if a certain state always tends to vote for the party that wins the election, that is said to be a bellwether state.
Sometimes the meanings of words change, and you just can't stop them from changing, especially if the word gets used for something we didn't have a word for, but really needed one. So we just have to put up with it and try to go on with our lives.
People started calling the Burnside look "sideburns" because of where the hair was, on the sides of the face. And also the general was sort of incompetent, and he sometimes got things "the wrong way 'round." So that was another good reason to turn his name around backwards, too.
THE MAGNA CARTA
King John and the other kings who came after him did not always follow what the Magna Carta said, but the ideas in it were what English Law was later based on. And besides that, it became the ancestor of the American Bill of Rights.
Anyway, the Magna Carta was never really signed. In fact, historians think King John may not have even known how to read and write. But he did have a seal, so that is how he put his official kingly mark on the Magna Carta.
BURYING BODIES IN QUICKLIME
So what is quicklime anyway, and what does it really do? The chemical name for quicklime is calcium oxide, and it is this harsh alkaline stuff that you get when you heat limestone to a really high temperature. People figured out how to make quicklime thousands of years ago. They used it for things like mortar, treating corn, waterproofing boats, and maybe in Greek fire. Now people use it to make heat, light (limelight), petroleum products, plaster, cement, and paper. Which means that quicklime is really very useful -- unless you're trying to hide the evidence of a murder!
