This post follows on the 4 points I learned about people from the linguistic theories of Prof. Noam Chomsky. Please refer to “Chomsky, linguistics, and justice: Background” for a full introduction to this idea, and to the first in this series, “Chomsky, linguistics, and justice: Grammar is in every brain.”
2. We describe grammar, we don’t prescribe it.
Rules such as “no split infinitives” or “There’s no such word as ‘ain’t’” don’t exist in the linguistics that I study. Such rules are called “prescriptive” because they prescribe a particular way of speaking that goes against how people actually speak. The linguistic school to which I belong does not impose a certain way of speaking; instead, we aim to describe the way people actually speak. In this way, everyone who speaks a language is valued equally in how he or she speaks.
