When I think about the rules of grammar I sometimes recall the story—and it’s a true one—about a lecture given in the 1950s by an eminent British philosopher of language. He remarked that in some languages two negatives make a positive, but in no language do two positives make a negative. A voice from the back of the room piped up, “Yeah, yeah.”
Don’t we all sometimes feel like that voice from the back of the room? When some grammatical purist insists, for example, that the subject has to go before the verb, aren’t we tempted to reply, “Sez you!”?
English is not so much a human invention as it is a force of nature, one that endures and flourishes despite our best attempts to ruin it. And believe it or not, the real principles of English grammar—the ones that promote clarity and sense—weren’t invented by despots but have emerged from the nature of the language itself. And they actually make sense!
