It might be time to update your vocabulary—1,400 new terms and phrases and 700 new senses of existing terms were added to the Merriam-Webster Unabridged dictionary. According to a blog post on the company’s site, some of the words are more technical (microloan and giclee are new entries), while many of them are slang words or abbreviations (like athleisure and ICYMI). The editors of the new version wrote that the updates “offer a kind of snapshot of how exactly our language expands” and that they had monitored the words for years before deciding to add them.

In addition to the new words and senses, the Merriam-Webster editors also updated the dictionary with revised and enhanced entries, plus thousands of new example sentences in word descriptions.
