PEP 3102 and PEP 570 say Keyword-Only Arguments but they should say Keyword-Only Parameters because a keyword-only parameter is the parameter which only accepts a keyword argument.

Actually, PEP 570 correctly says Positional-Only Parameters because a positional-only parameter is the parameter which only accepts a positional argument.

Glossary explains a keyword argument and positional argument.
