Linguistic Criticisms

Linguistic Criticisms focus on the language of the text itself, with "language" referring also to internal structures, signs, styles, etc.

There are five main types:

1. Formalism
2. New Criticism
3. Structuralism & Semiotics
4. Post-Structuralism & Deconstructionism
5. Reader-Response Criticism
