The longest English dictionary word is a "created word":

* Pneumonoultramicroscopicsilico-volcanoconiosis (45 letters, no hyphen)

It is considered "factitious" (false) by some dictionaries, and some other candidates may be considered in the same way:

* Supercalifragilisticexpialidocious - coined nonsense word (34 letters)

* Pseudopseudohypoparathyroidism - technicalmedical term (30 letters)

* Floccinaucinihilipilification - coined word (29 letters)

* Antidisestablishmentarianism (28 letters - longest unchallenged word)

Much longer are chemical names and words created in literature, which are not dictionary words.
