The dictionary just got a bit heavier because the people at Merriam-Webster added 640 new words on Monday.

Maybe you’ve heard your gym buddies announce they’re going to get “swole,” or you’ve referred to picking up your morning coffee in a “go-cup”.

If people are talking about a new movie or TV show, it’s said to be “buzzy”.

According to editor-at-large, Peter Sokolowski, words have to reach “critical mass” in order for these words to be included. So, that means they have to be showing up in daily usage.

Any of the words on this list familiar to you? Can you guess what the ones you don’t know mean?
