People often use uninterested and disinterested interchangeably to mean “bored” or “unconcerned” or “not interested.” But these words are not synonyms. Using the wrong word can completely change your intended meaning, and you can’t be having that.
Uninterested: bored, not concerned, not interested
Disinterested: impartial, unbiased, not having a stake in something

The etymologies of these two words are quite interesting and show how strange language can be. Essentially, their meanings were switched:
Uninterested meant “unbiased.”

Basically, these words usurped each other’s original meaning. The evolution of language doesn’t always make sense, but it is interesting.
