Update: OMG! LOL! FYI the Oxford English Dictionary Added New Words!

According to the OED‘s site, the newest edition of the dictionary revises more than 1,900 entries and includes a ton of new words, including LOL, OMG and FYI. These words often uses in online form, as a shortform of Laughing Out Loud, Oh My God and For Your Information.

According to the OED’s blog post - “The intention is usually to signal an informal, gossipy mode of expression, and perhaps parody the level of unreflective enthusiasm or overstatement that can sometimes appear in online discourse, while at the same time marking oneself as an ‘insider’ au fait with the forms of expression associated with the latest technology.” These three will be joined with other entries such as IMHO, TMI and BFF which also carries some meaning which can be found online or in informal discussion.

The heart sign (read: <3), however, is perhaps the most interesting addition. This update may be the first English usage to develop via the medium of T-shirts and bumper-stickers. Personally, I'm looking forward for the next edition, which hopefully can include some more of internet lingo such as tl;dr, TITS OR GTFO, STFU, nufags useful shortform in the language.

Update: OED added the word 'hentai' too in their latest update. Oxford's online entry for hentai is as follows;

Pronunciation: /hɛnˈtʌɪ/

a subgenre of the Japanese genres of manga and anime, characterized by overtly sexualized characters and sexually explicit images and plots.
