Limelight is white light – intense/bright – made by heating a piece of lime in burning oxygen and hydrogen.
The process to create a bright light was developed by Thomas Drummond (sp?) in the early 19th century. It was used in 19th century theatre to illuminate the stage.
So…it was once a bright light, thanks to a lime…and used in theatre.
Oh, the column archive search is an entirely different beast than the board search. I’m not even sure they’re on the same server; in any case, they’re entirely separate from one another.
I had idly wondered why both calcium oxide and the green fruit (and birdlime*, for that matter) shared a name, but never enough to look it up. The answer, of course, is that the words are unrelated.
The calcium compound and sticky bird stuff comes from Latin limus meaning “slime”, whereas the fruit comes from Arabic limah meaning, well, lime.
*For a long time I thought “birdlime” was a euphemism for bird droppings. I still sometimes hear it used to mean that.
