A more thorough explanation:

A donor is someone who gives something to another person or organization without expecting anything in return. This can be money, property, or other assets.

For example, a wealthy individual may donate a large sum of money to a charity to help fund their programs. In this case, the individual is the donor and the charity is the recipient of the donation.

Another example could be a parent giving their child a car as a gift. The parent is the donor and the child is the recipient of the car.

Overall, a donor is someone who willingly gives something to another person or organization without expecting anything in return.
