 
            Other types of nouns are proper nouns (or real nouns).
Real nouns start with a capital letter: Spain, Brad, and Pizza Hut.
What are proper adjectives?
This is the same with adjectives.
Most adjectives are common adjectives: slow, modern, red, and exciting.
Proper adjectives start with a capital letter: Spanish, Martian, and Russian.
Proper adjectives are usually derived (formed) from proper nouns.
Spain = Spanish
Mars = Martian
Using capital letters in English might differ from other languages. Here are some guidelines:
The word 'I' is always written with a capital letter. Newspapers often use capital letters for headlines. We also use capital letters in these situations:
The first word in a sentence.
   The first word of direct speech.
   When starting a quotation.
   For titles and ranks – Captain Sparrow
   Proper nouns – names, days, months, roads, cities  etc.
   Adjectives which are nationalities or languages.
   For poetry.
The  colon can be used to give details of a word or phrase before it:
 I  have many hobbies: running, dancing and playing the violin.
 I’ve  got quite a few things to do this weekend: do the shopping, put my winter  clothes away and collect my friend from the airport.
 The  islands have many attractions: wonderful beaches, a vibrant nightlife, good  shopping and an interesting history.
The  apostrophe is used to show that a letter is 'missing'. This is most common in  contractions:
   I'm,  he's, we'll, don't, can't, won't and o'clock (of the clock) etc.
The apostrophe is used to show possessions. Here are the ways this is used:
Add  's to a singular noun:
   The  mobile that belongs to Mary - Mary's  mobile.
   The  car that belongs to my neighbour - My  neighbour's car.
We use a question mark after a direct question but not after an indirect question. It is a common mistake to put a question mark after an in direct question.
Indirect questions
   Here's a direct question:
   ‘What do you want?’ she asked.
   The indirect question is:
   She asked me what I wanted.
   Most indirect questions are used in reported speech.
Here are the main uses of a comma (,)
Before 'and' or after the name of a person who is  being spoken to.
   Sarah, where are you going?
   Who are you speaking to, Peter?
   It seems to me, Mary, that you were right about  the forecasts.
Between items in a list.
   He bought wine, pasta, a chocolate cake and a lot  of other delicacies.
We use a full stop at the end of a sentence. Some people also put full stops after abbreviations.
Using an and a does not depend on the spelling of the word it comes before, it depends on the pronunciation of the word. In most cases though, an is used before words that begin with vowels (a, e, i, o u.):
an apple
   an elephant
   an igloo
   an oven
 an umbrella
If a word starts with a consonant sound, use a.
a ball
   a car
 a doll
