If you are a member of a social networking (社交的) website such as QQ, Kaixin, MySpace or Facebook,
you can add a new friend by sending someone a friend request (请求). If you later fall out with that person,
what do you do? You can hit the "unfriend" button (操作框) and remove (移走) him or her from your friend list. That means you won't talk, exchange information, or see each other's updates (更新) on the website any more.
That is a quick way to solve problems, isn't it? In fact, "unfriend" is often used on social networking
websites. It has become so popular that Oxford University Press recently chose it as the 2009 word of the year.
Experts at Oxford University Press look at how the words of the English language change from year to
year. They choose words that are popular and have important cultural meanings.
Christine Lindberg, editor for Oxford's dictionary program, said the word "unfriend" is popular now and
may stay popular for a long time. People understand its meaning in the online social networking context
(上下文), and also accept it as a modern verb. So it makes an interesting choice for the Word of the Year.
How to use the word? You can say "I decided to unfriend my roommate on Facebook after we had a fight"
or "I unfriended Alice on MySpace when she said something bad to me."
