The words disinterested and uninterested look similar, but these two words have a subtle difference in meaning.
To be disinterested is to have no strong feeling one way or the other about a topic. A disinterested person has nothing to gain from either side of an issue and can be completely impartial and unbiased.
Susan was disinterested in the topic being discussed, and she did not care to vote.
Because he had no pets, Brent was disinterested in the new condo rule about dogs.
If you want a fresh and unbiased view on a topic, seek out the ideas of a disinterested person.
On the other hand, the word uninterested conveys the idea of boredom and complete disengagement.
Mark is uninterested in math, and he usually sleeps through class.
Samantha is uninterested in going to college, so she doesn’t try too hard to get good grades.
Jack didn’t bother listening because he was uninterested in their topic of conversation.
Remember: A disinterested person is unbiased with no strong opinion either way and nothing to gain from either choice. An uninterested person is completely bored and tuned out on a topic.
