Semiotics:
-The study of signs and meanings.
-People use semiotics as a way of developing your own thinking about meanings.
Signs:
Iconic Signs; Look like what they actually represent, for example we use a picture of a wheelchair to signify that the facilities are accessible to disabled people.
Symbolic signs; Meanings that are learnt, they do not look like what they represent.
Indexical Signs; Have no connection to what they represent.
