Here's why:
* Syllable structure: Words are built from syllables, which are units of pronunciation with a single vowel sound.
* Complexity: Words with a very high number of syllables become increasingly difficult to pronounce and understand.
* Usage: Extremely long words are not commonly used in everyday language and are often created for specific purposes like technical terminology.
The longest word in the English language is "pneumonoultramicroscopicsilicovolcanoconiosis" with 45 letters and only 11 syllables.
