You're just being silly now.

No. The English term still means the same thing. The standard defines terms
**using English words** but within the scope of the C++ standard, they have
the meaning ascribed to them by the standard. The standard defines what
"argument" means. That doesn't mean I can't have an argument with clowns on
the internet, it just means that **within the scope of C++** that word has
a specific meaning, as defined by the standard.
