14 of The Hardest Words to Say in English | Beelinguapp Blog (2024)

Do you ever wonder how many words there are in the English language? Some say there might be around a million words, but do we really know the exact count?

The Second Edition of Oxford Dictionary recorded an entry of 171,476 words being used. On the other hand, Webster’s Third New International Dictionary, Unabridged together with its 1993 Addenda Section noted a total of 470,000 words. So if we combine both numbers together, the sum would be 641,476 words.

But is that the exact count of words in the English language? The answer is no. The number of the recorded English words in the two dictionaries don’t really determine the number of words out there. However, one thing is certain: each year, between 800 and 1000 new words are added to the English dictionary.

Words vary. Some are simple and short. Some are long and complicated. But one thing is in common – words are powerful. They make up a sentence. They make up a story. They make up a language. And when it comes to learning a new language, words are important.

Well, did you know you can learn a new language by reading stories you love? Think about reading beloved childhood classic stories like Peter Pan in Italian or Winnie the Pooh in Spanish. The possibilities are endless, so get Beelinguapp now and discover the magic of learning a new language through reading.
