NEW YORK: "Unfriend" has been named the word of the year by the New Oxford American Dictionary, chosen from a list of finalists with a tech-savvy bent.

Unfriend was defined as a verb that means to remove someone as a "friend" on a social networking site such as Facebook.

"It has both currency and potential longevity," said Christine Lindberg, senior lexicographer for Oxford's US dictionary program, in a statement.
