Every human language has grammar, including languages that have never been written down. Grammar is not something added by teachers. It grows with the language.
Because meaning needs shape
Words alone do not make a message. Listeners need to know who did what, when, and to whom.
Dog man bite. — Who bit whom? Grammar answers the question.
Because speakers need speed
Grammar lets us speak quickly without explaining everything. Both speakers already share the pattern.
I have finished. — The listener knows it is done and relevant now.
Because languages change
As a language is passed from parents to children, and from place to place, small changes appear. Some become patterns. Over centuries, those patterns become grammar.
Because writing came later
Grammar existed long before grammar books. The first English grammars were written in the sixteenth and seventeenth centuries, to describe a language that people had spoken for a thousand years.
People spoke English for centuries before anyone wrote a rule about it.
Because groups agree
A community of speakers shares expectations. That shared expectation is what makes understanding possible, and it is what we call grammar.
Words to remember
- grammar — the patterns of a language
- pattern — a repeated shape
- community — a group of people together
- describe — to say what something is like
