Our subject today is a pair of rather confusing words: uninterested and disinterested.
According to the Oxford Dictionary of Current English, the word uninterested means simply, "not interested." For example:
My friend invited me to the opening of a new restaurant, but frankly, I was uninterested.
The students in the class seemed uninterested in the discussion about Renaissance art.
As for the word disinterested, the Oxford Dictionary of Current English defines that word as "not influenced by personal feelings" or "impartial." Here are examples:
A good referee takes a disinterested approach to every game.
Readers trust the film critic for her disinterested way of writing reviews.
Not surprisingly, the Oxford Dictionary of Current English includes a usage note that warns speakers and writers not to confuse the words disinterested and uninterested.
That said, it's important to share something the research uncovered. Fowler's Modern English Usage points out that the word disinterested was used to mean "uninterested" back in the 17th and 18th centuries. That usage went into hibernation for a couple hundred years, but then it resurfaced in the 1970s—when of course, it met with resistance from grammarians.
Erroneous as it may be, there is some logic to it: The prefix dis- can mean not, as in disorganized. So it makes sense that people confuse disinterested and uninterested.
Nevertheless, Fowler's, just like the Oxford Dictionary of Current English, recommends restricting disinterested to mean "impartial" and uninterested to mean "not interested."
When possible, we on Grammar Grater like to provide tips or hints to help keep confusing words separated. We'll admit these hints are kind of silly, but anything goes in the world of mnemonics.
- Uninterested, which means "not interested," begins with U-N-I. Think of those as standing for "YoU Not Interested"
- Disinterested, meaning "impartial," begins with D-I-S. Think of those as meaning "Don't Involve Self"

While I have used both terms correctly, I had never considered the differences side by side. In law, the term disinterested has meant having no conflict of interest although bring very interested in the issue or no preconceived bias or prejudice much like the state of mind expected of trial judges or jurors.
Thank you so much!!!!
Nina I agree with what you said about "effect" & "affect". Maybe Luke will do an Article on the meanings and uses of these two words. I use both of those words in many of my writings.
Thank you for this interesting and informative Article Luke.
Thanks for the clarification.
Thanks so much for your comments and extra thoughts you brought to the discussion.
Nina and René, you two mentioned affect and effect, and it turns out we did a Grammar Grater on that not too long ago. If you'd like, here's a link to the article so you can read and listen:

Thanks again, everyone!
A careful writer may choose sense 1a of disinterested [not interested] in preference to uninterested for emphasis . Further, disinterested has developed a sense (1b) [no longer interested], perhaps influenced by sense 1 of the prefix dis-, that contrasts with uninterested .
