* Dictionary definitions: Dictionaries vary greatly in size and scope. The Oxford English Dictionary (OED), considered the most comprehensive, lists over 600,000 words.
* Technical and specialized terms: Fields like science, medicine, and technology constantly generate new words, making it impossible to count them all.
* Proper nouns: Names of people, places, and organizations are technically words, but they are countless.
* Slang and informal words: These change frequently and are not always recognized in dictionaries.
So, the number of words in the English language is constantly evolving and impossible to definitively count.
