One of my favorite things about language is it’s fluidity. It evolves and changes along with people. As people change, language changes with us. In many ways this is good, as long as we’re not talking about the “dumbing down” of language.
Merriam-Webster has added a bunch of new words, including flexitarian (that’s me!), game changer, geocaching, and… F-bomb! Of course, these aren’t all the words being added, so feel free to take a look at the actual list.
When I was younger, my favorite word was “troglodyte.” It’s fun to say, and was even more fun to call people, since few knew what it meant. Nowadays I don’t really have a favorite word. I’m more fond of how they all go together than just one in particular. Still, the addition of more words means more choices for writers, and that’s never a bad thing!
