Which language would be harder to learn?
I had an easier time with Arabic than German. And Writing right to left was strangely natural for me.
Chinese from what I hear is very difficult to learn fluently as a second language.
I can't imagine learning either of those. Seems it would be impossible.
Actually, both Chinese and Arabic are what are called a Cat-5 or Category 5 languages on the 1 through 5 scale for native English speakers. Japanese and Korean are the other languages that carry the same designation. However, my personal opinion is
that though Korean is difficult due to the grammar & Arabic reading and writing is challenging for us, Chinese is the most difficult due to the tonal element. Learning the characters is no picnic either.
Chinese is tonal, so much harder
Chinese by far!
Arabic is way easier.
I speak Hebrew so I have to say Arabic would be easier. They have very similar words. I can actually understand some words just because of the similarities.
The reason that Chinese is harder is because Arabic uses the same concept of an alphabet - a certain number of certain sounds to form meanings. Chinese, when written, is essentially more elegant hieroglypics (apologize for butchered spelling).
