Apparently a "naevus" is a birthmark. Who knew that we had a perfectly good word for birthmark in the past? Why did naevus go out of use, I ask? Was it too close to navel? I don't think I'd get my naevus and my navel mixed up. Although apparently, according to my mother, I used to be terrified of my naevus. I had to be told it was an "angel kiss" in order for me not to freak out when I saw it. I don't remember. I was a child. I was so young I don't even remember this occuring. It just shows how odd I was even as a child.
To clarify, naevus can also mean a growth, apparently, but typically it means a mole, or a large mole. Now the world is aware of my freakish mole that caused me to freak out as a child.
My sister, who I'm sure would love for me to talk about this, has an unsusual naevus of her own. Her's is in the shape of a cat. She tells me that if she were an Egyptian back in the day, she'd be venerated as a goddess because of her cat-like naevus. She's probably right. Some people have all the luck when it comes to naevuses.
