We added more than 300 updated and new definitions to Dictionary.com!

We updated our dictionary! You now have a new and improved Dictionary.com. How can something be both “new” and “improved”? We added 183 new words and updated 146 existing definitions to reflect our ever-evolving language. We also added more detailed notes about word usage, word history, and synonyms to some very particular words, like zucchini, expediate, and assume.

Even though we don’t constantly think about it, language changes subtly every day. Vocabulary is one way to measure this linguistic shift. When we add new words to the dictionary, we recognize they are now being used by a substantial portion of the population. (We do not just add words that we think should be used.) How do we choose which words to add to the dictionary? Learn more about neologisms and codification here.

A few popular words from last year made the cut, including tebowing and Zumba. Some words aren’t new to the language, but have acquired new meaning. For example, aught is now used to describe the last decade. Here are a few more of our favorites:

adjectivize
couch-surf
demonym
dead zone
QR Code
pixelate
aggregator
cyberbully
cognitive map
anyhoo

Are words ever removed from the dictionary? Oh yes. Learn how here.
