RULES FOR CAPITAL LETTERS

          

1. To begin a sentence:

     i.e. My father will be fifty tomorrow.

2. To begin sentences of direct speech:
     i.e. She said, ‘You will be sorry for this in the morning. You never learn.’

3. For the pronoun ‘I’ wherever it comes in the sentence:
     i.e You know that I have no money.
 
4. For all proper nouns – names of:
People( Mary Browne ), Countries (Pakistan, Saudi Arabia), Languages (Arabic, Urdu, Punjabi, English, Persian etc.) , Religious festivals (Eid, Diwali, Easter, etc.),  Firms (Express Cleaner, ), Organizations (the British Broadcasting Corporation), Historical period (Mughal’s period, the Victorian Period), Days of the week (Monday, Sunday, etc.), Months of the year (September, June, etc.)

Note these adjectives derived from proper nouns also have a capital letter: a Jewish festival; a German poet , However, the capital is dropped when the connection with the proper noun becomes lost: venetian blinds, French windows.
