PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS (45 letters; a lung disease caused by breathing in certain particles) is the longest word in any English-language dictionary. (It is also spelled -koniosis.)

Hawkes Bay Tourism's Internet site says that Porangahau in New Zealand's South Island, "boasts the longest place name in the world: Tetaumatawhakatangihangakoauaotamateaurehaeaturipuk-apihimaungahoronukupokaiwhenuaakitan arahu, officially entered in the Guinness Book of Records."
