The Global Language Monitor estimates that in the modern world a new word is created every 98 minutes. Each year, an estimated 800 to 1,000 new words are added to English language dictionaries (in the 20th century alone, more than 90,000 words have been added). Editors of the third edition of the Oxford English Dictionary (OED), to be completed by 2037, estimate that the rate of inclusion of new words into the OED are about 4,000 per year. In 2014, the OED added more than 2,500 new words.
This dramatic increase in new words is largely due to technology, and how people spontaneously coin new words in their email and text transmissions that spread quickly and efficiently via social media. A large percentage of new words are portmanteau words, also called blended words — a word that combines the meaning of two discrete words; for example, cineplex is formed from cinema and complex, bromance is formed from brother and romance, staycation is formed from stay and vacation. You get the idea.”
