In your opinion, what is the most difficult language to learn? For me it's Chinese.

Reading AND writing correctly? Greek. That is what makes the phrase "It's all greek to me" poignant. Though proper English is almost impossible for all. Save the very select few.

they say English is. I only speak English so I wouldn't know

It was German for me. Thats why I gave up lol

English. it's the only language I know and I am horrible with it.

That would be the most difficult one for me too.

I think Japanese is harder.

Ive heard that its mandarin

probably cantonese or manderin.

For me, the language of love... 😔

All of them

Hungarian

Chinese languages (Cantonese or Mandarin) would be on my list, too, along with Japanese, Russian and Greek.

I found Polish to be incredibly hard to learn.
