Here's why:
* Language and usage are constantly evolving. New words are coined, and long words can be combined into even longer ones.
* Dictionaries and word lists are not exhaustive. There's no single, authoritative list of every possible word.
* Syllabification is not always straightforward. There are rules, but also exceptions and variations depending on pronunciation.
However, there are some examples of incredibly long words:
* Pneumonoultramicroscopicsilicovolcanoconiosis (45 letters, 11 syllables) - a lung disease caused by inhaling very fine silica dust.
* Floccinaucinihilipilification (29 letters, 8 syllables) - the act of estimating something as worthless.
* Antidisestablishmentarianism (28 letters, 10 syllables) - opposition to the separation of church and state.
In conclusion: While there's no absolute limit, the examples above showcase the remarkable lengths that words can reach!
