How many words exactly are in the English language? The second edition of the current 20-volume Oxford English Dictionary contains 171,476 words in current use. That’s a lot!


Which gets the mind thinking the next question, what’s the longest word in current use today?

Many of the longest words in the dictionary refer to medicine or chemistry. You’ll find a few defined in here along with other long words that you may or may not already use.

Here’s how Merriam-Webster defines the ten longest words in the English language.

2. Hippopotomonstrosesquippedaliophobia (36 letters)
