CMV: English is an objectively hard language to learn, especially its spelling.

Disclaimer: my native language is Dutch, and the only other language I speak fluently is English. I know some Spanish, French and German to but not anywhere close to fluency.

I want to discuss this topic because this is quite hard to get perspectives on, and since I am not a linguist I am not aware if there is any science to back this intuition up.

The first reason why I think English is hard is its spelling. While there are always exceptions, most languages have rather consistent rules to put letters into sounds. But English is just a mess. The cliche example is ghoti (fish), but besides all examples of inconsistent spelling I found that (anecdotally) native English speakers (who learn from hearing) make more spelling mistakes than non-native speakers (who more often learn from reading) because there is not a very strict relationship between sound and letters. Conversely, this means that as a non-native speaker you are going to mispronounce a lot of words at first. This issue gets even worse when you consider the large number of homophones, words spelled the same but with different pronumciation and meaning.

Then there is the grammar. The meaning of a word depends mainly on its place in a sentence. For me personally, since Dutch works similarly, this was not as hard to learn, but I can imagine that if you are not used to it it must be quite difficult. I also saw people who were learning Dutch really struggle with this. In my opinion languages where the role of a word in a sentence is also denoted with a prefix or suffix  are easier to learn.

So CMV: while the difficulty of learning a language is for a large part subjective, English has some unique features that make it harder than most other languages (which is ironic considering its current lingua franca status).

Since "most" is a bit of a weasel word, this is mainly about other European languages, but examples of exotic languages that are even more terrible to learn are also welcome.

English isn't gendered. 

In most other languages, you have to worry about whether the word for boat is masculine or feminine, you have to worry if the word for mailbox is male or female. 

Not so with English. Non-people are just genderless. 

This makes English much easier to learn, since you don't have to memorize a gender and definition for each word, only a definition.
