neologism

The English language is constantly picking up neologisms. Recently, 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 at the beginning of the 19th century, when English speakers first borrowed it from the French nèologisme. Its roots, however, are quite old. Ultimately, "neologism" comes from Greek neos (meaning "new") and "logos" (meaning "word").
