gall – podictionary 414
The podictionary word for today is gall: It takes a lot of gall to submit an invoice to your lawyer for the time you sat in his waiting room. The meaning of this sense of the word gall is boldness or effrontery. The sense comes from the bitterness involved in such bold moves since the gall bladder contains a bitter yellow fluid.
The fluid is named gall because it is yellow and the root of its name goes back to Indo-European and was also the source of the name for that yellow metal we all covet so much, gold. But funnily enough there are two other types of gall. If something galls you, it means it gives you pain. In this case the word gall evolves from an Old English word for the places on a horse where a saddle or harness has rubbed the skin raw. A swollen knob on a tree is also called a gall and this is from Old French.
There is some suspicion that the swollen knob gall and the open sore gall might have the same roots, but maybe not. Gall the bitter yellow fluid is also known as bile and it is important in our digestive system. It would have been important to treat the galls on your horses if you expected to get much work out of them. But what kind of importance could the galls of trees have? In fact, for the purposes of English etymology tree galls had a fair amount of importance, particularly the galls of oak trees. What would happen you see is that a little wasp would come along and drill a hole into the bark of an oak tree and plant her eggs in there for safekeeping.
The tree did not like this, not one little bit. And so the tree grew a knob around the wasp eggs to protect itself. But when the monks and scholars of 1000 years ago saw one of these oak galls, they knew that inside was a little store of acid produced by the tree. They happily crushed the oak gall and used water or vinegar to draw out the acid, then added gums to make the mixture a little less runny, and then added their favorite mixture of rust and soot and other things to give the liquid whatever color they wanted. The result was something they called encaustum in Latin, we’d call it ink, but the word ink didn’t come into use until Middle English.
It was the acid from the oak gall that gave the ink the power to etch its way into the surface of the velum on which they wanted to write. The velum was made from animal skins, mostly sheep and it’s because these ancient scribes took the time to use such high quality methods and materials that we can still read today what they wrote way back then. If they had used paper it would have crumbled to dust or blacked with oxidization long before now. Encasutum is related to caustic and both words go back to a Greek for burn. So even though these different types of gall seem to come from different etymological sources, they all have a sting to them.
