by Jove(redirected from by Jove!)
An exclamation of surprise or praise. You studied hard, and, by Jove, you got an A! Isn't it funny how that works? By Jove, we've solved the mystery!
Also, by cracky. Used to express surprise or emphasis. For example, By Jove, I was glad to see her, or It was a great day, by cracky. These mild oaths are euphemisms, the first for "by Jesus" or "by God" (Jove is another name for Jupiter, the principal Roman god), and the folksy variant by cracky for "by Christ." Both idioms may be dying out.
Used as a mild oath to express surprise or emphasis.
