                       Use of Articles

              An article is a word that describes a noun. It is used before a noun to show whether it is specific or not. In English
              grammar there are three articles— A, An, The. They fall into the following two categories: definite and indefinite.


              Definite— The
              "THE" is a definite article which is used before a noun that indicates something clear or obvious. For example:
                 • The sun shines bright today.
                 • Give me the book on the table.

                 • The air quality is very bad in this place.

              Indefinite— A, An
                 • 'A' and 'An' are indefinite articles which are used before a noun that are not specific or known before. "A" is used
                before a word beginning with a consonant (alphabets other than vowels) sound. For example:

                   ✶ A book (it can be any book)
                   ✶ A game (it can be any game)
                 • "An" is used before a word that begins with a vowel(a, e, i, o, u) sound. For example, an umbrella, an hour, an ice
                cream cone, etc.

                       When no Articles are used


                 • For common/general things. For example:
                   ✶ Fruits are good for health.
                   ✶ Do not eat medicines without doctor's prescription.
                 • Before a country, continent, island, mountain and lake' name. For example:
                   ✶ New Delhi is the capital of India.
                   ✶ Nagpur is famous for oranges.
