The difference between 'disinterested' and 'uninterested'

For today's post, I will talk about the difference between 'disinterested' and ' uninterested'.

If you are not interested in something that meets your eyes, you are uninterested in it.
For example, you can write a sentence such as the one below:
Pupils often are uninterested in History lessons because they are usually boring.

As for disinterested, it means 'impartial' or 'neutral'. Let us say a football match is held and we need a judge, we should choose someone outside the two competing teams to do the job. A sentence to illustrate this point will be as follows.
We invited a disinterested man to judge our football match.

So much for 'disinterested' and 'uninterested'.
