公司产生在西方:世界上最长的单词

pneumonoultramicroscopicsilicovolcanoconiosis [医]硅酸盐沉着病,矽肺病
以上过去在电视节目中讲过。
现在又有一说，最长的单词是“色氨酸合成酶A蛋白质”

本人认为该单词完全由表示氨基酸的词缀构成，表示了一个完整的氨基酸序列。如此推来，随多肽测序技术的发展，一定还会有更长的单词出现，但这样的单词不实用，一定有简称。所以本人推荐第一种说法

如果按2楼的smiles的话那smiled也可以呵呵！以前高中时就经常出些脑筋急转弯！
如果楼主从智力测验的方面提问的话：smile首位隔了一英里（mile)为答案！
如果是从正规的单词字母长度来看应该有个单词含182个单词（看以下资料）
但是我以前学英语时好象记得有更长的（出自莎士比亚的作品）！
