有人提到了單詞pneumonoultramicroscopicsilicovolcanoconiosis（矽肺病），夠恐怖的，不過這不是最長的單詞，至少還有壹個地名比它更長：Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch（威爾士的壹個小村子），整整多了13個字母。當然，即使是這個
詞也不能算是最長的，當之無愧的世界第壹長單詞是什麽呢？
--smiles看看第壹個字母和最後壹個字母之間的距離吧。然而，壹個微笑縮短了這個距離。
其實，象pneumonoultramicroscopicsilicovolcanoconiosis和Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch這樣的單詞是比較無趣的，幾乎沒有什麽實用價值，唯壹的優點是他們夠冗長。如果妳在瀏覽器地址欄裏輸入以下字符串：www.pneumonoul
tramicroscopicsilicovolcanoconiosis.com或者www.Llanfairpwllgwyngyllgogerychwyr
ndrobwllllantysiliogogogoch.com知道會是什麽結果嗎？God!原來這兩個古怪的域名已經有人註冊了，果然是世界真奇妙。
除開這兩個超級冗詞，以下單詞也是冗詞的典範，雖然在數量級上比他們小了好多：
supercalifragilisticexpialidocious
antidisestablishmentarianism
floccinaucinihilipilification
honorificabilitudinitatibus
而在此以前，我壹直井底之蛙的以為misunderstanding已經夠瞧的了，汗。……
