Or who ARE the grammar police? (Depending on whether the Atlantic is to your left or your right).
anyway - I teach in a school in the US. It's report writing time of year and we're having our annual debate over the use of commas. It's all good natured, but there are some big differences in opinion about when to use a comma for certain types of sub clause and/or compund sentences.
Next year we're planning to put together some statement banks of common phrases we use, so that we can cut down how much time we spend on writing reports. It would be nice if we could all agree.
However, we all have various grammar books (from various decades) which give conflicting/different answers.
So - if you're looking for a definitive answer on grammar ( in the UK or the US) Who would you see as the governing body/grammar police? Who is in charge?
