to the coined word
pneumonoultramicroscopic-silicovolcanoconiosis (45 letters, no hyphen)
to the
complete long chemical name for the protein titin (189,819 letters).

The longest dictionary word in English (although it was created for that purpose in 1935) is:

Broken into syllables, that's "new-mono-ultra-micro-scopic-sili-co-volcano-con-ee-oh-sis."
There are longer chemical names, including the name for the protein titin, which is 189,819 letters long, too long to include on these pages. (see the related link)

Other contenders
1) In German, where adjectives can be added to nouns to form single words,
Donaudampfschiffahrtselektrizitäten-hauptbetriebswerkbauunterbeamten-
gesellschaft
(79 letters, no hyphens) is said to be the longest published word.
2) The Oxford English Dictionary contains pseudopseudohypoparathyroidism (30 letters) and electrophotomicrographically (28 letters).
3) The longest word in any major English language dictionary is pneumonoultramicroscopicsilico-volcanoconiosis (no hyphen), a 45-letter word supposed to refer to a lung disease contracted from the inhalation of volcanic ash, but research has discovered that this word was originally intended as a hoax, created at the 1935 meeting of the National Puzzler's League. It has since been used in a close approximation of its originally intended meaning (the disease silicosis) lending at least some degree of validity to its claim.
4) The ancient Greek comedic playwright Aristophanes created a word of 183 letters that describes a fictional dish by stringing together its ingredients.
