Oxford English Dictionary
For the March 2011 release of OED Online, they have selected for publication a number of noteworthy initialisms—abbreviations consisting of the initial letters of a name or expression. Some of these—such as OMG [OMG int. (and n.) and adj.]: ‘Oh my God’ (or sometimes ‘gosh’, ‘goodness’, etc.) and LOL [LOL int. and n./2]: ‘laughing out loud’—are strongly associated with the language of electronic communications (email, texting, social networks, blogs, and so on). They join other entries of this sort: IMHO (‘in my humble opinion’) [IMHO at I n./1], TMI (‘too much information’) [TMI at T n.], and BFF (‘best friends forever’) [BFF at B n.], among others.
The latest update of the OED, published on 24 March 2011, revises more than 1,900 entries and adds new words from across the dictionary. The OED‘s chief editor, John Simpson, provides some observations on the revisions in this update, while Graeme Diamond and Katherine Martin comment on some of the most interesting new words in the batch. A full list of new words can be found on their website.
