The four longest word that could be found in a dictionary are: Antidisestablishmentarianism with 28 letters and 12 syllables. It is a noncoined and nontechnical word, Floccinaucinihihilipipification with 29 letters and 12 syllables. Coined and longest nontechnical word Supercalifragilisticexpialidocious with 34 letters and 14 syllables. A coined word in the song Mary Poppins, and Pneumonoultramicroscopicsilicovolcanoc… with 45 letters and 19 syllables. It is the longest word found in a major dictionary.

Antidisestablishmentarianism. Or Supercallifragilisticexpiallidocious, but that's not really a word. And whatever the word in the answer just above is, I have no idea if it exists, because I've never heard of a word that long that isn't Welsh.

I vote for the word: "Antidisestablishmentarianism" There are other words that are longer, but most of them are "coined phrases". But I think "Antidisestablishmentarianism" is the longest "real" english word I've heard of.
