  • "The New Oxford American Dictionary has named unfriend - as in deleting someone as a friend on a social network such as Facebook - its word of the year. Oxford University Press USA, in a blog post, said unfriend, a verb, had beaten netbook, sexting, paywall, birther and death panel for the honour.

    'Unfriend has real lex-appeal,' said Christine Lindberg, senior lexicographer for Oxford's US dictionary program. 'It has both currency and potential longevity,' she said. 'In the online social networking context, its meaning is understood, so its adoption as a modern verb form makes this an interesting choice for word of the year.'"
