GRAMMAR
Grammar is the system of a
language. People sometimes
describe grammar as the
"rules" of a language; but in
fact no language has rules. If
we use the word "rules",
we suggest that somebody created the rules first
and then spoke the language, like a new game.
But languages did not start like that. Languages
started by people making sounds which evolved
into words, phrases and sentences. No commonly-
spoken language is fixed.
