It's often said that English is the hardest language to learn, seconded only sometimes by Mandarin Chinese. To the native English speaker, this doesn't seem possible when English uses so many of the same Greek and Latin roots as other European languages. But I think a quick read of this poem will show you English's mind-melting capabilities.
In fact, over 90 percent of English speakers won't be able to pronounce all the words in this poem. Can you?
