US's glamorous politician Sarah Palin is in the news again -- this time, for apparently trying to invent new words while tweeting about plans to build a mosque near the 'Ground Zero' site in New York.

The former Republican vice-presidential candidate, who often uses the micro-blogging site Twitter to communicate her views, made three attempts before writing an error-free entry which can only contain 140 characters.

In her first effort, she asked "peaceful Muslims" to "pls refudiate" the mosque.

Having invented a word, in her second attempt she used "refute" incorrectly, calling on "peaceful New Yorkers to refute the Ground Zero mosque plan". Both those messages were removed from her page, though not before being salvaged by US news websites. The third attempt remains.

By way of explanation for her errors, the former Alaska governor posted a fourth "tweet" that said "English is a living language. Shakespeare liked to coin new words too", the media reported.

The substance of her messages prompted a strong response -- on Twitter -- from an aide to Michael Bloomberg, the Mayor of New York.

Andrea Batista Schlesinger tweeted: "@SarahPalinUSA mind your business" and in a second entry implied that Palin was "racist". Both messages were later removed from her page after media enquiries to New York city hall.
