English is an expansive language, anyone who has seen the size of an unabridged English dictionary can tell you that. It's also a language that's ever changing and evolving, so of course there are some words that fall out of favor and are hardly ever used, but maybe it's time to bring some of them back!
//nO-va-'tUr-E-ent// Although this word has not yet been listed in Merriam-Webster and Oxford English Dictionary but it has been used by many writers to describe someone/ something that desires change or alterations. This word has its Latin roots from the words nova which means new and turire which means the desire to/for. Literally meaning the desire for something new. @ravivora
