Abstract:

The word genre comes from the French (and originally Latin) word for 'kind' or 'class'. The term is widely used in rhetoric, literary theory, media theory, and more recently linguistics, to refer to a distinctive type of 'text'*. Robert Allen notes that 'for most of its 2,000 years, genre study has been primarily nominological and typological in function. That is to say, it has taken as its principal task the division of the world of literature into types and the naming of those types - much as the botanist divides the realm of flora into varieties of plants. However, the analogy with biological classification into genus and species misleadingly suggests a 'scientific' process.
