Primarily, Saussure looked into the system of signs and a variety of signifiers, which are the physical forms of signs so what is being looked at. He also looked at what is being signified, what is being implied learnt and taught from this physical form. He came to the conclusion that the relationship between both the sign and what it means, is decided and agreed on as we attach them to the certain object. Also that without this universal thinking no one would understand ad would have various interpretations.
However Piece, delved deeper into semiotics and concluded that with every sign, there is a multitude of meanings and understandings. That these meanings can be attached to the signifier and are varied depending on their audiences.
Denotations and connotations come hand in hand with semitics and this just explains what is seen by the audience and what is then thought afterwards. For example a Heart can be seen in various ways; the physical organ which pumps blood through the bod, however a heart has connotations of love, romance and valentines.
