I listed some of the recent new entries in the OED in my post a couple of days ago. As well as the addition of completely new words and phrases, other recent amendments to the Dictionary concern existing entries. One of these is the word wireless. In the first edition of the OED in 1926 the entry for wireless extended over five paragraphs. Now there are over eighty paragraphs devoted to it.
At one point it looked as if wireless was a dying word. In the 1920s the word wireless was common for a radio receiving set, but eventually the word radio became more popular. The word wireless has been saved by the advent of mobile phones and laptops. New entries in the OED in 2009 under the main headword wireless include wireless technology, wireless device, wireless router and wireless service.
