Besserwisser

"Here's a word you might enjoy: Besserwisser, a know-it-all," my husband offered. "It's German."

No.

He was right. It is a useful word. We all know one. Or are married to someone who eventually becomes one or always was one but kept it inside better. Or something.

I love these translation aids. They turn solid grammar and creative words into a garbled mess that most resembles the way my brain processes information.

Google will also translate these for you.

Just a sampling. I will keep looking, but later. I have a day job. Sort of.
