USE OF CAPITAL LETTERS
SENTENCES should always begin with a capital letter; a fact of which most people are aware. The difficulty is in determining where new sentences should begin.
DIRECT SPEECH, where a speaker's actual words are being quoted, always begins with a capital letter.
Eg. Tom said, "We will meet you tonight at eight."
Alice whispered, "I think you should go home now."
"I think you should go home now," whispered Alice.
The PRONOUN "I" is always written with a capital letter wherever it occurs in the sentence, even if it is run together in a contraction (I'm, I'd, I'll, I've, etc.)
I am going away at the weekend.
My mother said that I should not go.
I'd rather stay at home.
PROPER NOUNS always begin with a capital letter. Proper nouns are the names of particular people, places or certain types of object.
Eg. First names: Charles, Elizabeth.
Surnames: Churchill, Obama.
Titles: Mrs Simpson, Sir Arthur Conan Doyle.
Organisations: Hull University, Hull City Football Club.
Countries: France, Spain.
