Isn't a programming language both? Sure the goal is arguably to communicate some process for the computer to perform in a machine-readable way. But I can easily write two valid semantically equivalent programs which produce equivalent code when fed to a standards compliant compiler. However, one of these programs may be much more readable to a human because it follows an established set of coding practices. Perhaps a better word that standards would be "conventions" but either way, most programs also need to be read by humans at some point.
