genre

And another thing:

Genre is not the same as structure. Genres usually have a structure, though there is a certain amount of malleability in the structure for the particular works in a given genre: less for a sonnet than a novel, more for a comedy than a tragedy (and at one point does something stop being a novel and become something else which is novel-like? Difficult.) What distinguishes structure from genre? Do particular genres have a particular kind of content? No. What is there to a piece of writing besides structure and content?
