Sarah Palin is no William Shakespeare. Or maybe she is.

According to the former U.S. vice-presidential candidate, her newly created word – 'refudiate' – is her contribution to the “living language.”

“Shakespeare liked to coin new words too,” she said.

That's according to a tweet following her use of the word – something of a mix of 'refute' and 'repudiate' – a couple of times in recent days.

She first used the term on July 14 on Sean Hannity's Fox News show, when she asked Michelle Obama to “refudiate” claims that the Tea Party movement is racist.

On the weekend, the former Alaska governor used the word again in a tweet: "Ground Zero Mosque supporters: doesn't it stab you in the heart, as it does ours throughout the heartland? Peaceful Muslims, pls refudiate."

That tweet was later deleted and replaced with one that used the word 'refute' instead.

But Palin shot back Sunday night with another tweet defending her new term: "'Refudiate,' 'misunderestimate,' 'wee-wee'd up.' English is a living language. Shakespeare liked to coin new words too. Got to celebrate it!”

Former U.S. president George Bush mistakenly and famously used the term 'misunderestimate', and Barack Obama coined 'wee-weed up' almost a year ago in referring to stirring up a situation.

'Refudiate' has already hit urbandictionary.com, where its meaning is still being debated.
