@lcamtuflcamtuf I understand why people think this, but I actually don't think it's true at all. It only seems that way when you encounter a new subject for the first time, and the unfamiliar jargon makes your head spin. But properly getting your head round something like tropical geometry is SO much harder than remembering the terminology, that really even if the terminology were somehow so magically perfect that it took no effort at all to learn, the overall difficulty of learning the material would be identical up to a rounding error.
