An Eminent Scientist
When used in the context of describing a person, eminent means that the person is a well-known or respected authority within their particular professional area. This usually carries a positive connotation, implying that the person is famous for having done some important or influential work within their sphere of expertise.
For example, you could say that Jane Goodall is an eminent scientist when it comes to chimpanzees. You could also say that Warren Buffett is an eminent investor and philanthropist.
An Imminent Earthquake
By contrast, imminent has an entirely different definition. It can be used to describe an event or state of affairs that is ready to take place, particularly one that can occur at any moment. Imminent can usually be used interchangeably with impending.
The most common example, thanks to Hollywood movies, is to say that someone is in imminent danger. If the police are hunting down a fugitive and they have not only narrowed down his location, but have also developed a strong case against the fugitive, you could say that jail time is imminent for that crook. Similarly, thanks to the shifting of the tectonic plates, you could also say that a big earthquake is imminent for the Vancouver area.
Putting It All Together
Just as there is a monumental difference between ever so often and every so often, imminent and eminent are entirely different words too. Here’s an example that brings the big picture into focus.
Dr. Stephen T. Colbert, an eminent analyst of American politics, believes that the ousting of Barack Obama from the White House is imminent.
