2545: glass, chlorine, & arsenic Dec 1, 2021

The word 'glass' in other languages shares a root with many color-words, but that is far from where the root *ghel- ends. Meaning 'shine', this word also led to many light-associated words like 'glaze', 'glow', 'gold', 'glimmer' 'glare' and more, but also many related to bile like 'chlorine', cholera, and 'gall'. Even 'arsenic' comes through this root, though it was adopted into English through many other languages, ultimately from Old Iranian *zarna- (golden).
