                                               SECTION B (Subjective Type Questions)

              A.  Short answer type questions.

                  1.  Define Semantics.
                Ans.  Semantics is about the meaning of words, phrases, and sentences. It looks at how we understand and interpret these
                    meanings when we use language. For example, the word “bat” can have different meanings depending on the context
                    of a sentence. A bat can refer to a flying mammal (the animal). A bat can also refer to a piece of equipment used in
                    sports like baseball or cricket.
