neologism

The English language is constantly picking up neologisms. In recent decades, for example, computer technology has added a number of new terms to the language. Webinar, malware, netroots, and blogosphere are just a few examples of modern-day neologisms that have been integrated into American English. The word neologism was itself a brand-new coinage in the latter half of the 18th century, when English speakers borrowed the French term néologisme. The word's roots are quite old, ultimately tracing back to ancient Greek neos, meaning "new," and logos, meaning "word."
