1.
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the game alive", so to speak.

5.
A term created by software pirates to describe a game or program that has been "abandoned" by its creators and is no longer available in stores. Of course, this has no legal standing, and the copyrights were never abandoned, so downloading abandonware is just as illegal as downloading a new release.
