Oxford English Dictionary Adds ‘Crowdsourcing,’ ‘Big Data,’ and ‘Mouseover’

For those in tech circles, these words have always been legitimate.

But in the eyes of the English Oxford Dictionary, that’s not always so. This year, it has finally decided to add the likes of “crowdsourcing,” “big data,” and “mouseover” to its list of real words. The dictionary has also expanded the definitions of “follower” and “tweet” as a result of Twitter’s booming salience.

“There has been a threefold increase in instances of the word tweet between 2006 and 2007 (when Twitter began), and by 2012, this had increased to 50 times,” the OED wrote in a blog post.

The dictionary also added the word “e-reader” to describe, well, e-readers.
