Retweet, sexting and cyberbullying may be meaningless to some but they are among a host of new entries appearing in the Concise¹ Oxford² English Dictionary for the first time today.

转发，发送性短信和网络欺凌这几个词也许对某些人来说没有什么意义，但是今天它们却和其他新词条一道首次被收录到《牛津简明英语词典》当中。

But its new centenary edition includes a copy of the 1911 version, which shows Britons thought the words neon（霓虹灯） , petticoat（衬裙） , and 'indecent dance' the Cancan all deserved similar recognition.

The brand-new dictionary contains more than 240,000 words, phrases and definitions, reflecting language used widely in the UK today.

Retweet - to repost or forward a message on Twitter, sexting - the sending of sexually explicit³（明确的，清楚的） photographs or messages via a mobile phone, and woot - used in electronic communication to express elation⁴ enthusiasm or triumph, all make the book.

Also fashionable Jeggings - tight-fitting stretch trousers for women and the mankini - a brief one-piece bathing garment for men with a T-back, made famous by comedy character Borat, are in.

But the 1911 limited-edition dictionary included with its 2011 counterpart, offers a glimpse into a world where exciting new words included 'marconigram（无线电报） ' - a message sent by Marconi's wireless⁵ telegraphy system; 'kinematograph' - an apparatus⁶（装置，设备） producing motion pictures; and 'biplane' - a two-winged aeroplane.

'The 1911 dictionary was a lot smaller than the latest version and is phrased more quaintly⁷ in some places, but my overriding⁸ impression of it is how good it was,' Angus Stevenson, an editor of the 12th edition of the dictionary said.

Words from the fashion world of 1911 show how much the world has changed since brothers Henry and George Fowler compiled their first edition in their Guernsey cottage.

It includes 'blouse' - then defined as a workman's loose linen⁹（亚麻布） or cotton garment - 'frock' - a monk's long gown with loose sleeves and 'petticoat' - a skirt dependent from waist, worn by women, girls and young boys, either externally or beneath gown or frock. Both are additionally defined as women's garments in the current edition.

But it has emerged that new technology and social trends also played a major part in the creation of the first edition in 1911, and some words were considered just as racy（生动的，猥亵的） .
