orthography - Longest word in English

What is the longest word in English?

Answer

Pneumonoultramicroscopicsilicovolcanoconiosis takes the prize, I believe. It's a miner's lung disease. Outside of a doctor's office in a coal-mining community, however, one tends to hear it only when people are discussing the longest word in the English language — perhaps only slightly less often than one hears antidisestablishmentarianism.
