It all depends on the background of the person. The amount of exposure to the particular language and the ability of the learner. For some it may be the pronunciation , for some it may be the grammar , for some it may be a breeze. For example if I were a French speaker and I am learning English it would be a little easier for me, as there are many common vocabularies between them if in comparison I wanted to learn Russian. Similarly an Arabic speaker would find it a little easier to learn Hebrew since it is read from right to left if you compare to a Japanese speaking learner and vice versa. BUT you must keep in mind results also vary from person to person according to the level of interest and amount of work invested to dedicate themselves to learn a particular language. Each language is unique and all of them deserves to be treated as it is. No language is harder than so and so, or no language is harder than so and so, it is unfair since it totally varies from person to person. Most importantly is the dedication and the amount of love for what you are doing, even so, no matter whether you have tremendous amount or a minimum experience, all what matters is, you enjoyed the learning process and that's what learning is all about! FUN!

I studied Korean first, and now I'm learning Chinese. They're both very challenging, but in different ways. The Korean writing system and pronunciation are very easy, while the grammar is very difficult. I find Chinese grammar to be very easy (so far), while the writing system and pronunciation are incredibly hard. In fact I never really had any problem pronouncing foreign languages until I tried Chinese tones. So it really depends on what language you're learning.

Every language has four sections........reading.....writing.....speaking......understanding. I think the.....understanding......is more difficult than others.

hi... The difficult part is the accent and the spelling...

The hardest part is to put into practice what you have learnt and being able to communicate with another person and be understood.
