You may need a new dictionary this new school year. About 400 words are added to one popular reference, the Oxford Concise English Dictionary, illustrating changes in everyday language. It's no shock that many technology-related words are among 12th edition newcomers. They include sexting, retweeting and cyberbullying, along with noob (properly spelled n00b) That shorthand for newbie is an unflattering term for a newcomer to a forum, game or trend.

Another fresh entry is woot (or w00t), an online way to say hooray. "The expression woot began in America, but was picked up very quickly by people in Britain as a result of the Internet breaking down international boundaries," says Angus Stevenson, editor of the dictionary. The book from Oxford University Press in England also adds updated definitions of familiar words. Thought a cougar was just an ornery wild cat? By now you probably know it's also "an older woman seeking a sexual relationship with a younger man."

Here's another: Textspeak is defined as any writing with lots of abbreviations, initials and emoticons, just as in text messages.
Not all added words may survive in the next edition, following the fate of cassette player -- too old school for the latest dictionary. It's a 240,000-word version of the authoritative Oxford English Dictionary, filled with 600,000 words and phrases. The smaller dictionary, first published in 1911, is meant to "cover the language of its own time," the publisher says.

Editor says: "New words come into currency much more quickly as a result of the Internet as people see friends, or friends of friends, using new words and copy them." -- Angus Stevenson of the Concise Oxford English Dictionary

Upcycle means: "To recycle into something worth more that the original." -- From new dictionary

Denialist means: "A person who refuses to admit the truth of a concept or proposition that is supported by the majority of scientific or historical evidence." -- From new dictionary
