Which language is the hardest to learn?
According to the rest of the world, Russian and English are just about the hardest languages to speak. Although most people who speak those think it is easy, it is because it comes first nature to them.
The answer to the hardest language to learn in the world is largely subjective -opinion- and depends on what your native language is. No language is easy to learn, but those languages that are closely related to your native language are definately going to be easier to learn than ones that are not.
Having said that, this is still subject to debate. Most poeple say they find difficult to learn Chinese and Arabic languages.
There are three:
1). Burushaski - a language spoken by a small group of people in Pakistan, that until recently was not believed to have relation to any other language.
2). Diné bizaad (Navajo) - it's been said that unless you are born a native speaker, you can never learn to speak the language well.
3). English - oddly enough, English is an extremely difficult language to master. Part of the reason for this is the tendency for loan words to creep into the vocabulary, and the huge lexicon of cliches, phrases, and icons that exist. The language is so difficult to master that even among native speakers there are few who have complete mastery.
