The concept of signs has been around for a long time, having been studied by many classic philosophers such as
Plato,
Aristotle,
Augustine,
William of Ockham, and
Francis Bacon, among others. The term
semiotics derives from the Greek root
seme, as in
semeiotikos (an 'interpreter of signs'). It was not until the early part of the 20th century, however, that Saussure and American philosopher
Charles Sanders Peirce brought the term into more common use. While both Saussure and Peirce contributed greatly to the concept of signs, it is important to note that each differed in their approach to the study. It was Saussure who created the terms
signifier and
signified in order to break down what a sign was. He diverged from the previous studies on language as he focused on the present in relation to the act of
communication, rather than the history and development of words and language over time. French semiotician
Roland Barthes used signs to explain the concept of
connotation—cultural meanings attached to words—and
denotation—literal or explicit meanings of words. Without Saussure's breakdown of signs into signified and signifier, however, these semioticians would not have had anything to base their concepts on. ==Relation between signifier and signified==
