Signs

Sign = A symbol which shows a meaning or instruction.

Signifier = The object itself. 

Signified = what something represents.

Polysemic = Refers to the capacity of all signs, to be 'many signed' i.e. to have more than one meaning.

Connote = The interpreted meaning of a sign.

Denote = the literal meaning of a sign.

Symbolic = Those which are learnt.

Indexical = Those which work through a casual link. i.e smoke as an index of fire.

Structuralism  = Meaning is only created by knowing what it is not.
