Hiii everyone...!!! Which is the toughest language in the world?

I thought trying to learn japanese was tough but mandarin good lord.

English. Cough though, tough, through are all pronounced differently even though they all have "ough" in them. Not enough time to mention all the stupidities of the spelling and pronunciation of words spelled differently that sound the same as well.

Chinese

Mandarin

For me I'd say Arabic or Gaelic.
