The English language is constantly evolving, even more so in today's digitally-driven world, so some of these words may already be known to you from entries in the urban dictionary or slang dictionary. some are internet-speak while others are more specific to the tech world. Not every word that's new to the dictionary is necessarily "new", some culinary terms have been around for a while, and the new list also features abbreviations of common words.
For example, The Oxford English Dictionary contains more than 829,000 words, senses, and compounds. Experts in various specific fields are consulted by OED’s researchers before deciding if a neologism (a newly coined word or expression) should be added to Oxford’s list.
In order to qualify, a word needs to be used for "a reasonable amount of time" and in numerous independent examples.
Here is just a sample of some of this year's newly added words:
