Mandolin Chinese is a hard language to learn. My cousin speaks the language.
I have a friend who is trying to learn the language.

I know of a way to learn Mandolin.



If you want to learn Mandarin, then use this instead:

When i was studying Russian language
and culture, my instructor did indeed say,
that English was one of the hardest languages
for them to learn.

English is hard to learn in those and other ways, due to the complex history of the English people who built the language. It is assembled from multiple sources,just as the peoples of England are themselves the result of the intersection of conflicting groups colliding.

Irish/gaelic is the hardest language for me. I am quite good in foreign languages, but I utterly fail here

Hihi, funny compilation.
We got similar things in Dutch, probably in every language. Good thing about (foreign) language learning is that you aren't confronted to such things, you build up from scratch.
And even foreign learners of English pick up on things almost like native speakers as we're exposed to it so much in music and movies.

If memory serves, English is difficult to learn for dyslexic people as the spelling is totally weird. Think of words like daughter, laughter, thought and so on.

I've been busy with Scottish Gaelic for a while. It is quite the challenge, especially if you want to be able to not only speak it, but also write it. I never can remember or work out when you have to use an accent, nor which one (the 'and `) and even more advanced speakers of the lingo often don't seem to know.
In a way it's about discovering the structure on which the grammar / lingo is built, but with Scottish Gaelic I find it difficult to fathom.

i think english also has more exceptions to rules than it has rules

I still remember well, when I was a child in what used to be called Grammar school (it was already called Elementary by the time I got there), how a teacher began one lesson by writing this in large letters on the blackboard:

"GHOTI"

She then asked if anyone knew this "word," and what it meant. I remember being too cautious to answer, but wondering why the word for "small beard" would be spelled so oddly.

Turned out she was facetiously bringing to our consciousness, how "funny" English word spellings can be, due to the wide variety of ways we had to learn to pronounce letters and letter combinations.

The correct pronunciation of the word she'd written, was "FISH."

This was due to taking the way we pronounce the word "tough," and snipping off the GH at the end; taking the word "women," and using the way we pronounce the O in that, and finishing with taking the word "diction" (or any similar tion word), and using how we pronounce the "ti" in that.

Again, all due to our insistence on keeping SOME but not all old ways of writing things.

Another "fun" thing about English (again, no doubt not unique to it) is that we did completely discard SOME letters we used to have, altogether, yet left the remnants of them in word spellings, and thereby confusing later generations.

We used to have a letter that looked a lot like a modern capital Y, but which was pronounced like "TH" as used in "the." This is why you might see someone set up a sign saying "Ye Old Apothecary" or the like, and most people will actually say "yee" out loud when they read it. Not even the people who make that sign, often realize it should be pronounced "THE Old Apothecary," because that letter discard has been forgotten, while the words using it remain in our collective usage.

English is the easiest language to learn.
I learned it in 9 months at home with a dictionary and subtitled movies.
Of course, the difficulty is proportional with the language spoken by the pupil and his abilities to learn.

My mother spoke 7 languages : Dutch, French, German, Arabic, Spanish, English and Italian.
She always said English was the easiest language for her to learn. Now that I speak English, I agree with her.
