5. German
If you are an English speaker, you might find it too challenging to pick up German. You’ll see a lot of incredibly long words. The pronunciation is rough and makes your tongue ache. Some claim that the German language is descriptive. How difficult the grammar is depends on your native language. After all, it will influence the learning process.
6. Hindi
You might find it surprising how many words in the English language have Hindi origin. Who doesn’t know words like yoga, karma or guru? All of them are Hindi. Also, English is an official language in India hence both languages have something in common. It is interesting that some words written in Hindi are pronounced the way they are pronounced in English (‘station’, ‘doctor’ etc.). What will take you some time is to start writing in Hindi since the system is quite unique.
