sesquipedalian: (of words) long; having many syllables.
So, what is the single word with the most syllables?
And the answer ... (which we all learned as tots): Antidisestablishmentarianism. Or is it?
Here's more, from Bookrags:
The longest word in any major English language dictionary is pneumonoultramicroscopicsilicovolcanoconiosis, a 45-letter word supposed to refer to a lung disease, but research has discovered that this word was originally intended as a hoax. It has since been used in a close approximation of its originally intended context, lending at least some degree of validity to its claim. See the separate article for details.
The Guinness Book of Records, in its 1992 and subsequent editions, declared the "longest real word" in the English language to be floccinaucinihilipilification at 29 letters. Defined as "the act of estimating (something) as worthless", its usage has been recorded as far back as 1741. In recent times its usage has been recorded in the proceedings of the United States Senate by Senator Robert Byrd [1], and at the White House by Bill Clinton's press secretary Mike McCurry, albeit sarcastically. It is the longest non-technical word in the first edition of the Oxford English Dictionary.
Antidisestablishmentarianism (a nineteenth century movement in England opposed to the separation of church and state) at 28 letters is one of the longest words in the English language.
The longest word which appears in William Shakespeare's works is the 27-letter honorificabilitudinitatibus, appearing in Love's Labour's Lost. This is arguably an English word (rather than Latin), but only because he used it.
The humuhumu-nukunuku-a-pua‘a, or reef triggerfish, is Hawaii's official state fish [1]. At 21 letters (22 counting the okina) it is one of the best known very long one-word names for an animal. It is often asserted that the name is longer than the fish.
Although only fourteen letters long, sesquipedalian deserves a mention. It is derived from a nonce word used by the Roman author Horace, in his work Ars Poetica (The Art of Poetry). The quote is as follows: "Proicit ampullas et sesquipedalia verba," which means, "He throws aside his paint pots and his words that are a foot and a half long". The Oxford English dictionary[2] lists sesquipedalianism ("the practice of using words one and a half feet long"), and further derivations can be created as described in the Constructions section below.

In his play Assemblywomen, the ancient Greek comedic poet Aristophanes created a word of 183 letters describing a dish by stringing together its ingredients.
James Joyce, known for his distinctive style, made up nine 100- and one 101-letter long words in his novel Finnegans Wake, the most famous of which is Bababadalgharaghtakamminarronnkonnbronntonnerronntuonnthunntrovarrhounawnskawntoohoohoordenenthurnuk. Appearing on the first page, it allegedly is the symbolic thunderclap representing the fall of Adam and Eve. As this word appears nowhere else except in reference to this passage, it is generally not accepted as a real word. Sylvia Plath made mention to that word in her semi-autobiographical novel The Bell Jar as Esther Greenwood, the protagonist, was reading Finnegans Wake.
The well-known song title from the movie Mary Poppins, "Supercalifragilisticexpialidocious", with 34 letters, does appear in several dictionaries, but only as a proper noun, and defined in reference to the song title. Hence it may well be dismissed as not a real word, particularly since the song assigns no meaning to it other than to say it's impressive.
