Semiotics

Semiotics basically means the system of signs which was a theory from Barthes in the 1950s and proved the difference between a signifier and something to be signified.
It also covers the conventions of culture and the amount of learning we have in these three categories: symbolic, iconic and indexical. It's easy to identify what symbolic is e.g. a cross which symbolises Christianity.  Iconic is an accurate representation of the real like a photo and indexical is the most complex. It means that something as more potential meanings like smoke can signify fire. Juxtaposition is used in this to signify and denote objects with certain things e.g. the colour yellow could signify the sun and it could denote temperature (being hot).

Hope that's quite a good explanation of semiotics for all you students studying or maybe will study media studies!
