Futronym: a neologism that by common usage and functionality is clearly destined to be added to the lexicon at some future point. In part it will serve as an antonym to 'retronym.' See 'Antoneologym.'
Email and Eddress (email address) are both futronyms. The former will be elevated soon due to its common usage, while the latter shall come later owing to it's functionality. Both will soon be found in most dictionaries.
