Donor.

If its not a word why is my Oxford Desk Dictionary and Thesaurus telling me it is. Now whos word do I take, yours or the dictionaries. Better yet you tell me what you would do.

Wow lol.

The word "Donator" is a word.
Look on many business or charity shit..
It may have Thanks to all the donators.

Hmmmm I smell fail.

/amiright?

A Donator is a word. It is considered as someone who donates. A "donor" has basically the same meaning. It is a word. Case closed. Do i smell a bad case of fail?

A donor is more appropriate when it comes to things of importance such as donating a bodily organ, a donator is a more general word to use for simple things that are donated such as clothes and money.
