英文单词有多少个

The number of English words is estimated to be around 170,000. However, this number is constantly changing as new words are added to the language. It's important to note that not all of these words are used regularly in everyday conversation. Only a small fraction of these words are considered "standard" English and are used by most people. The exact number of standard English words is difficult to determine, but it's likely to be in the tens of thousands.
