You don't have to learn English to code but it's way easier.

Not an answer to OP's question, but I know in PHP there's at least one error message that's in Hebrew.

APL exists. To me it's about as fun as it is painful.

Do don't have to first learn english. You could learn the basic without it but don't except to be a good programmer if you are not confortable reading technical document in english.

While many languages read left-to-right and have other artifacts of English words order, you do not need to learn English first. Knowing English makes it easier, but learning English first would make it harder.

I know it's not exactly the question, but C/C++ allow you to override any keyword with #define, so if you wanted, you can turn it into another language. I don't suggest doing that, but hey, you can.

Also somewhat related, but some languages like C# allow you to use Unicode in variable names.
