un-和dis-都是否定前缀，按说，uninterested与disinterested的意义应当相同。
很多人把这两个词误认为是同义词。其实它们的语意差别是很大的。
uninterested in 是指“对……无兴趣的”（not interested in）、“不关心的”。它的反义词是 interested in。
-
I am uninterested in politics. (Wood) 我对政治不感兴趣。
-
I told him the news but he seemed uninterested. (Chambers) 我把这新闻告诉他,但是他好像不感兴趣。
-
Lionel was uninterested in the house. (EED) 莱昂内尔对这所房子没有兴趣。
disinterested 则作“无私心的”“公正的”“公平的”“无偏见的”解：
-
A judge must be disinterested in the cases he tries. (FWF) 法官在审理的案子中必须公正。
-
His action was not disinterested because he hoped to make money out of the affair. (LDCE) 他的行为不是没私心的,因为他想从此事中挣钱。
也有人把 disinterested 用作 uninterested,但人们认为这是错误的:
She seems completely disinterested in her work. 她似乎对她的工作毫无兴趣。
