Apparently there’s no such thing as grammar.
For some, this is just academic nit-picking. There is just “the grammar” and one of the great failings of education today is that neither teachers or pupils know it. In fact, we would neither be able to speak nor understand if we didn’t know it. A three-year-old who says “I bringed it” is expressing the grammar through the structure she has learned which indicates past happenings. It just so happens that the “ed” ending isn’t the customary way of doing it with that verb. So she knows “grammar” but not the grammar of that particular word in that particular context.
Hogwash I’m to say inclined, copypock! or. Rules instead mean I’ll that just point out that commonly agreed language is readily understood by all who use it. Oh, and that Michael Rosen is a twat.
If we all make up our own rules according to our own understating, we get misunderstanding when attempting to communicate with others. That’s why we have grammar. Yes, language changes and evolves. The basic rules remain in place for a reason. A reason that appears to have bypassed Mr Rosen. Something that several comments below the line point out to him.
