The word 'twerk' – describing the sexy dance now synonymous with Miley Cyrus - may date back to 1820, according to the Oxford English Dictionary.
Defined as dancing "in a sexually provocative manner, using thrusting movements of the bottom and hips while in a low, squatting stance", it is one of 500 new entries to the latest edition of the OED.
But researchers found that the word was first used as a noun in 1820, spelt 'twirk', to refer to a "twisting or jerking movement" or twitch. The verb is believed to have emerged by 1848, and the 'twerk' spelling was popularly used by 1901.
While the exact origin of the word is uncertain, it may be a blend of the words twist or twitch, and jerk.

15/15 Miley successfully sheds her Hannah Montana image
This is Miley Cyrus? Yes. Are you kidding? Nope. The pop star has been desperately trying to shed her squeaky-clean Disney image all year. But have her efforts gone too far now?
The dance move has been closely identified with Cyrus since her performance, alongside Robin Thicke, at the MTV Video Music Awards in 2013 and 'twerk' first entered the online Oxford dictionary in the same year. But its roots lie in the New Orleans ‘bounce’ hip-sop scene of the 1990s.
Among the other new entries to the OED, are ‘twitterati’ – describing users of the social media service and ‘fo’ shizzle’, meaning ‘for sure’.
‘Meh’, an interjection expressing lack of enthusiasm, has also been included in the latest Oxford English Dictionary. The word is believed to have been first used in 1992, before being popularised by cult TV cartoon The Simpsons.
For a word to qualify, it must have been used in novels and newspapers for at least 10 years.
Fiona McPherson, senior editor of Oxford English Dictionary, said: "We are confident that it is the same origins as the dance. There has been constant use up into the present day to mean that same thing.
"I think it's quite spectacular, the early origins for it. We were quite surprised."
Ms McPherson said the new entries had "earned their place" in the history of the English language.
