The English language is a 'living language'; it grows, develops and changes.
New words come into the language all the time, and are absorbed into it without so much as a blink of an eye. These include foreign words, and even slang words, or words coined as a result of new technology as it sprints on, and attempts to leave behind, in its dust, the language that will describe it.
With this in mind, TheSpoof.com has put together a short list of words that you may not have heard of before, along with their meanings.
