God's Speed

The Definition

A wish for success and safety given to someone embarking on a journey or a daring new venture. It is the linguistic equivalent of a "bon voyage," implying that the traveler should be favored by fortune and reach their destination without mishap.

The Deep Dive

This is a classic "junk knowledge" trap where the modern ear hears the word "speed" and assumes the phrase means "may God make you travel fast." In our world of fiber optics and supersonic jets, speed is a measurement of velocity. However, in the 14th century, "speed" had a much broader, more prosperous meaning.

The phrase comes from the Middle English Gode spede, derived from the Old English spēd. At the time, "speed" didn't mean miles per hour; it meant success, wealth, or good fortune.

  • The Prosperity Prayer: When a medieval person said "God speed you," they weren't hoping you would gallop your horse at a dangerous pace. They were saying, "May God grant you success" or "May God prosper you."

  • The Agricultural "Speed": The phrase was famously used in the "Plough Monday" traditions of England, where neighbors would shout "God speed the plough!" This wasn't a request for a faster tractor; it was a prayer for a bountiful harvest and a successful tilling of the soil.

The phrase was immortalized by William Tyndale and later the King James Bible, which used it to translate the Greek word chairein (to rejoice or be well). By the time the "velocity" definition of speed became dominant in the 1800's, the phrase was already a fixed idiom. We kept the words, but we lost the original "prosperous" intent, turning a prayer for success into a wish for a quick trip.

Fast Facts

  • The Space Connection: The phrase saw a massive cultural resurgence in the 20th century during the Mercury and Apollo missions. Most famously, flight controller Scott Carpenter told John Glenn, "Godspeed, John Glenn," as he became the first American to orbit the Earth in 1962.

  • The "Sped" Link: The past tense of the original word is still found in the word "prosperous." To be "sped" in the Middle Ages was to be successful, not to be moving quickly.

  • The Farewell Pivot: "Godspeed" is one of the few religious idioms that survived the transition to secular life largely because it sounds more formal and poetic than a simple "good luck."
