What is literature?

Literature is the art of written work and is a use of language. Literature can be defined as:

1.-  A highly developed use of language in that is the stylised manipulation of language for larger effect (purpose) and/or affect (emotional response)     (Course companion, page 9)

2.-Writings in which expression and form, in connection withideas of permanent and universal interest, are characteristicor essential features, as poetry, novels, history, biography and essays.( dictionary references, literature)

It seems easy to understand what is literature but the problem come when you have to Analise and determine what is literature and what is not. I think that although when we think about literature we always think about maybe heavy books, literature is every piece of written work. It can be much more simple a  note than a novel, yes, but for me the fact that is being written and is have some sort of coherence, make it literature, although more simple than other types of literature.

The study of literature have many ways and theories about how a text must be analysed in order to be comprehended correctly and this cause many controversies.
