Countless new words are born every day. They are part of a perpetual process of birth and rebirth natural to all living languages. As you mostly unconsciously search your memory for words to express yourself, you use not only the words that are already there but also new combinations of familiar elements. The process is so normal that if often goes without notice, even by yourself...You can hardly spend a day without coining a new word or two.
