Capitalising on Capitals
Knowing errors relating to capital letters may help you avoid such errors when you submit your documents for copy-editing or proofreading.
It seems fairly obvious that you use “I” when you refer to yourself (first person singular). But proofreading experience tells a different story. English check shows that people use “I” correctly when they begin a sentence, make an error and use “i” when it is in the middle of a sentence.
Another common error which proofreading throws up often is not capitalising the initial letter of weekdays and months.
Copy-editing shows that many people do not use capitals on holidays. You can’t write, “John came home for christmas”. You should write, “John came home for Christmas”.
Abbreviations begin with a capital (e.g., “Mr”).
