Which are or were the most confusing words you had to learn in a foreign language?

For me, those were in English: tough, though, thought, through, thorough, and throughout. So confusing!

Which are yours?

It's a romanized Chinese story. That's why one needs to learn good tones. The Chinese text looks much better imo:

English:

<The story of Mr.Shi eating lions>

???There was a poet named Mr.Shi who lives in a stone den. He liked to eat lions, and vowed to eat ten lions. Therefore Mr. Shi would usually visit the market to look for lions. At 10 o???clock exactly ten lions just arrived at the market. At that very moment, Mr.Shi shot a few arrows from his bow and killed those ten lions. Mr. Shi then brought the ten dead lions back to his stone den. Because the den might be too wet to store the lions. So he ordered his servant to clean and dry the den. After the den was cleaned, Mr.Shi started to try to eat those ten lions. However, only until he was eating the lions he found out that those ten dead lions were actually ten stone lions. Would you try to explain what was happening????

To be honest, I'm still confused on some English prepositions: IN, ON, AT

That just freaked me out!

I'm kinda new in English, but the "on, at, in", etc. for me are still consfusing.
