The problem

The English language is a beautiful thing, capable of expressing precise thoughts and subtle meanings. But many people have problems with its written form. The complex rules of spelling, punctuation and grammar are confusing and often illogical, even to those who can speak English fluently.

If you get it wrong then you may find it difficult to get your message across, as readers struggle to understand what you were trying to communicate.

And if you break any of those petty rules, other people will judge you for it. They may think that you are unintelligent, or just careless with details. Students will lose marks. Businesses will lose investors and customers.

So it is important to get these things right.
