Polysemy

Roland Barthes said texts were either open or closed

He suggested none were fully one or other (as there is always room for interpretation), however some texts attempt to restrict their meaning more than others

Some texts encourage Polysemy (multiple meanings) and are open texts

Some discourage polysemy and are closed texts (one meaning and one way to intemperate). Like advertisements

This image is a closed text as it uses words 'Leadership' and 'National Interest' in reference to the Theresa May and uses the colour blue, which is associated with the conservative party. Meanwhile the image shows Theresa standing tall and emoting with her hands. The image also shows people listening intently to her words. It also uses anchorage as it links the image of Theresa May to the text and makes it easier for the audience to interpret
