* Language is constantly evolving: New words are created, old words fall out of use, and meanings shift.
* Different types of "words": Do we count only base words? Do we include inflections (different forms of verbs and nouns)? Do we include slang, technical terms, or words from other languages that are used in Serbian?
* No official dictionary: There isn't one definitive dictionary that captures all the words in Serbian.
What we can say:
* Serbian has a rich vocabulary thanks to its Slavic roots and influences from other languages.
* Dictionaries can provide a good starting point, but they won't capture the full range of words used.
* The number of words used in everyday speech is much smaller than the total potential vocabulary.
Instead of focusing on a specific number, it's more helpful to understand that Serbian has a vast and diverse vocabulary, constantly evolving and reflecting its cultural and historical background.
