英语单词多少个

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 and old words fall out of use. Additionally, different sources may have slightly different counts. The Oxford Dictionaries website states that there are around 300,000 words in standard English, while the Merriam-Webster dictionary has about 265,000. It's worth noting that even native English speakers may not know all of these words offhand, and many words are used only in certain contexts or by certain groups of people.
