Everyone has an opinion about grammar. Some people get upset about what they regard as bad grammar, and believe we must all ‘follow the rules’. But where do these rules come from? And are they all valid? In our Real Grammar series, Macmillan Dictionary re-opens the debate, this time insisting that the only reliable way of understanding English grammar is to study the evidence of language in use. We analyse corpus data and observe how people use English, around the world and across the whole spectrum of text-types.
