Every year, hundreds of words are dropped from the dictionary to make room for new words. Lexicographers spend hours researching word usage and may drop words that have been completely neglected by the society.
Here’s how. You adopt one such word through “Save the Words” and take a pledge to use that word more often in your daily conversations or written communication.
This will directly increase the chance of that word’s survival because the moment lexicographers see discarded words being used in conversations, they may re-include them in the dictionary. Wheatgrass is one such word that was reinstated after missing from the dictionary for several years.
There are hundreds of “lost” words already - vacivity, plegnic, mingent or primifluous for example - all of them, not surprisingly, failed by the Firefox spell checker as well. So go ahead, adopt bring back a nearly-extinct word. In return, you get this nifty certificate.
