Identify the interjection in the following sentence:
Hurrah! We won the game.
a. The
b. Hurrah
c. We
d. Game

Hint: Read the given sentence and decipher what it means. Point out the word which expresses emotion in the sentence or gives an idea of the tone/mood of the sentence. Then go through the options and select accordingly.

Complete answer: In this question, it will be helpful for the student to recall the concept of interjection. An interjection is an abrupt emphatic exclamation expressing emotion. An exclamation is an abrupt excited utterance.
Let us analyze the options given to us in this question -
Option (a.), 'The', refers to ‘the definite grammatical article that implies necessarily that an entity it articulates is presupposed; something already mentioned, or completely specified later in that same sentence, or assumed already completely specified’.
Therefore, option (a.) is incorrect as it does not have an exclamation. An interjection always has an exclamation.
Option (b.), ‘Hurrah', refers to ‘shout `hurrah!'’.
Therefore, option (b.) is correct as it has an exclamation, and interjections always have exclamations.
Option (c.), ‘We', refers to a ‘personal pronoun which refers to the speakers/writers, or the speaker/writer and at least one other person’.
Therefore, option (c.) is incorrect as it does not have an exclamation. An interjection always has an exclamation.
Option (d.), ‘Game', refers to a ‘contest with rules to determine a winner’.
Therefore, option (d.) is incorrect as it does not have an exclamation. An interjection always has an exclamation.
Therefore, option (b) is correct.

Note: Interjections are not normally used in formal writing, but they are common in speech (and therefore informal and fiction writing), where they show emotions such as anger, surprise and interest as well as convey hesitation.
