According to the authorities English does NOT have 'a' grammar since it didn't.

In the 1800s the Victorians decided to ape Latin by applying its Romanish rules to Anglish.

What a f****ng mess it all now is become.

We have Ozanglish, Yanglish, Canadanglish, Iranglish, Newzealanglish, Afranglish, which are a few main varieties - complete with their own unique spelling and Grammar Nazis!

What was so bad or wrong with the excellence of Locke, Johnson, even Shakespear?

I say to hell with Grammar and Grammar Nazis, let the English language again live instead of smother in endless gobblede-speckledeegook.
