Types of Noun

There are two main types of noun.

  Common Noun
  Proper Noun

Common Noun.Name of a common or a non-specific thing, place, or person is called common noun.
Common noun refers to a non-specific or non-particular thing, place or person.
For example book, pen, room, garden man, girl, road, camera, month, day, chair, school, boy, car, are common nouns because each of these nouns refers to a common thing, place or person.

Proper Noun.Name of a particular or a specific thing, place or person is called proper Noun.
For example BMW Car, April, Monday, Oxford University, New York, America, John, Newton, Einstein, R.H Stephen, are proper nouns because each of these nouns refers to a particular thing, place or person.
If a common noun is specified it becomes a proper noun. For example day is a common noun but if it is specified like Monday or Friday, it becomes proper noun. Similarly car is a common noun but if it is specified like BMW Car, it becomes proper noun.

Use of CAPITAL LETTER for proper noun.      

The first letter of proper noun is always written in capital letter.

         She studies in Oxford University.

  2. Article “the” is not used before the name of
    countries, cities, for example New York, Mexico, Canada, Toronto,
    London, Paris, America. But if the name of country or

    article “the” will be used before it. For example, the Philippines, the Netherlands, the United States

Countable and Uncountable Nouns

Countable Nouns.

A noun which can be counted is called countable noun.

Pen is countable noun because we can count it and can say one pen, two pens, three pens or more pens.  Pen, chair, cup, room, man, baby, bottle, dog, cat are examples countable nouns.

Singular and Plural noun (Countable Noun)

 A countable noun can be singular as well as plural. Article “a” or “an” is used before singular noun but not before plural noun.

If a singular noun starts with consonant letter then “a” is used before it, i.e. a book, a cat, a pen.
If a singular noun starts with a vowel letter or with consonant which
sounds like vowel in that word, “an” is used before it i.e. an apple, an umbrella, an onion, an hour.

Plural noun (Countable Noun)
Plural noun means more than one person, place or thing. Word “chair” is a singular noun but word “chairs” is plural noun.

  1.  Plurals are usually formed by adding –s or –es to singular noun for example book–books, cat–cats, box–boxes, tax–taxes. If a word ends with “y”, the “y” is changed to “I” then –es is added to make it plural, for example, baby–babies, lady–ladies. There may be some exceptions.
  2. Some plural are formed in different ways for example, man–men, child–children, leaf–leaves, wife–wives, foot–feet, toot–teeth, datum–data, basis–bases.  Such plurals are called irregular plural forms.
  3. Some nouns have same plural and singular form, for example, sheep–sheep, deer–deer, swine–swine.  

Uncountable Nouns.

Uncountable noun refers to substances which cannot be counted.

For example, water is an uncountable noun because we
cannot count it. We cannot say, one water or two water.  Such
substances which cannot be counted in terms of numbers are called
uncountable noun.
Examples: Water, milk, bread,
honey, rain, furniture, news, information, pleasure, honesty, courage,
weather, music, preparation, warmth, wheat
are examples of uncountable nouns.

Use of Uncountable Nouns.

Uncountable nouns are usually treated as singular
noun for auxiliary verbs in sentence but articles “a or an” are usually
not used before uncountable nouns.

       Water maintains its level.
       Necessity is the mother of invention
       His preparation was not good.
       The Weather is very pleasant today.
       This information is very helpful in solving the problem.
       The warmth of sun causes evaporation of water.

Uncountable nouns may be used as countable noun when
it refers to an individual thing. For example life is uncountable noun
but it be used as countable noun if refers to individual, lives.
It was feared that two lives had been lost.

We can also use word like “some, any, no, little, more etc” before uncountable nouns if needed in sentence.
         They have no information about the accused.
         There is little milk in the glass.

Changing Uncountable nouns into countable nouns.

We can change uncountable
noun into countable noun if we specify a unit or measuring standard for
it. For example “water” is an uncountable noun but we can make it
countable by saying one glass of water or two glass of water etc. In
this example we selected a unit that is glass. We can also say one
litre of water or one cup of water etc. By selecting such units or
measuring standards we can change uncountable noun in to countable
which can be counted in terms of numbers.
    Uncountable – countable
       Bread – a piece of bread.
       Wheat – a grain of wheat.
       Milk – a glass of milk
       Information – a piece of information
