Commonly Confused
Disinterested and uninterested share a confused and confusing history. Disinterested was originally used to mean “not interested, indifferent”; uninterested in its earliest use meant “impartial.” By various developmental twists, disinterested is now used in both senses. Uninterested is used mainly in the sense “not interested, indifferent.” It is occasionally used to mean “not having a personal or property interest.” Many object to the use of disinterested to mean “not interested, indifferent.” They insist that disinterested can mean only “impartial”: A disinterested observer is the best judge of behavior. However, both senses are well established in all varieties of English, and the sense intended is almost always clear from the context.

Explanation
If you can't decide whether to purchase the shirt with orange polka dots or the purple paisley-patterned one, you might seek input from a disinterested, or unbiased, party (who will probably tell you not to buy either one). Depending on whom you ask, disinterested is either one of the most commonly misused words in the English language, or a perfect example of usage experts and English teachers being way too uptight. While everyone agrees that disinterested can mean “unbiased,” the debate rages on as to whether it can also mean “uninterested” or “indifferent.” Sticklers are vehemently opposed to this secondary meaning. (Of course, you’ll also find the disinterested — or uninterested? — folks who couldn’t care less.)
