Times change, and so do languages. And in order to be useful, dictionaries must also be
tweaked every now and then. The lexicographers at Merriam-Webster announced today (Feb. 7) that they have added more than 1,000 new words to the dictionary, including many that are related to science, technology and medicine.
"These are words that have demonstrated frequent and increasing use in a variety of sources, and are therefore likely to be encountered by a reader — and should be in the dictionary," the dictionary-makers said in a statement. https://www.livescience.com/57790-merriam-webster-dictionary-new-science-words.html
