How to give novel a definition:-
A novel is a long fictive work of art. It is usually multi-themed and relies largely on grammatical dexterity of its author to bring out its best. Its structure differs from that of drama and poetry with most of its dialogues in quotation marks or revealed with indirect speeches. The Castle of Otranto by Horace Walpole is a good example.
