Save the dying words ... Adopt them

Words are living organisms that grow old and sometimes die. Many words have disappeared from the language for various reasons. To know about these words and perhaps breath a new life into them you have a chance. Visit the site savethewords.org to see a list of all such words and make a commitment to adopt one of them (or many of them). This site is put up by Oxford Dictionaries. Who knows about the health conditions of words better?
