什么是世界上最长的单词文字，这完全取决于个人的观点,曾经看到过一个统计里说到这样的问题。
正式最长的一个单词是:'floccinaucinihilipilification' 29个字母
一说是:'pneumonoultramicroscopicsilicovolcanoconiosis' 45个字母，不过是医学用词（矽肺病，黑肺病，医学原称）
最长的地名,是在New Zeland的 一座山: TAUMATAWHAKATANGIHANGAKOAUAUOTAMATEATURIPU
KAKAPIKIMAUNGAHORONUKUPOKAIWHENUAKITANATAHU
85个字母
最最长的一个单词是一种蛋白质的名称,有1913个字母：
是“色氨酸合成酶A蛋白质”
（一种含有267种氨基酸酶）的全称----
一般的字典上是见不着的。
可以翻翻医学专用词汇字典^_*
