I am delighted by words that make sense, especially when I take their sense-making for granted until a moment of epiphany, when it's like, "Ohhhhhh. That's why it's called that."
Here are a few potentially epiphany-inducing words for you. You're welcome.
As in: The final line of a calculation is where you sum everything up.
As in: Pea-nuts are like peas but have nuts instead of bean-ish bits inside an outer shell.
As in: You break the fast you held during the night by not eating food while sleeping.
I also enjoy clever alternative names for things.
Do I know the originator of these names? No I do not. Such information is potentially lost to the internet. But whoever you are, I appreciate you.
