Hundreds of words and expressions enter American English every year. Many of these words wither and die before being written or spoken by more than a handful of people, but a respectable number survive. Oxford lexicographers dive into the sea of language to catch these words as soon as they hatch; then they set about defining these additions to English, which may come from slang, other languages, technical jargon, or scientific breakthroughs. Oxford's rigorous standards result in definitions with the precision and accuracy that readers expect from the most trusted name in reference. With more than 2,500 new words, meanings, and derivatives, this unique collection will perfectly complement any standard dictionary. In addition to the definitions, entries include real examples (complete with attested sources), of the words being used in magazines, newspapers, books, and online, which further illuminate these embryonic words and their meanings. The backmatter will include a subject index, a bibliography, and a guide enabling word-loving neophytes to search out new words for themselves.
