The former vice-presidential candidate, who regularly uses the social networking website to communicate her views, made three attempts before writing an error-free Twitter 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 Twitter 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 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 Mrs Palin was racist. Both messages were removed from her Twitter page after media enquiries to New York city hall.
Would love to here from you...
