Usage

What does prosper mean? Prosper means to be successful or fortunate, especially in a financial or material way. Prosper often implies success in terms of wealth, health, and happiness. But it can also be used broadly, much like the words succeed, thrive, and flourish. You can say that someone is prospering in the present, but the word is perhaps most commonly used in the context of what will happen in the future. Prosper is associated with its use in the phrase “live long and prosper,” the catchphrase of the character Spock in the Star Trek series of TV shows and movies. Someone who prospers can be described as prosperous. The noun prosperity refers to a state of success. Example: If we can continue to maintain this level of quality, our company will continue to prosper.

Etymology

Origin of prosper

First recorded in 1425–75; late Middle English prosperen, Old French prosperer, from Latin prosperāre “to make happy,” derivative of prosperus prosperous

Explanation

As any fan of Star Trek knows, “live long and prosper” is good advice. The verb prosper means to do well, succeed, or thrive. The verb prosper commonly means to generate wealth, as in “she hopes to prosper from her new investments.” But more generally it means “grow stronger” or "flourish" — crops will prosper when they have adequate sun and water, and rescued animals can prosper in a loving home. You can also prosper from good advice or a wise decision: for example, “cheaters never prosper” is one piece of advice that might help you prosper.
