Semiotics Explained: From Saussure and Peirce to Barthes

Semiotics, the study of signs, emerged in 1960s academia as a tool for analyzing visual and linguistic communication. Ferdinand de Saussure defined the sign as comprising a signifier (word/image) and signified (mental concept). Charles Sanders Peirce categorized signs into iconic (resemblance), symbolic (arbitrary), and indexical (existential bond). Roland Barthes applied semiotics to photography, distinguishing denotation (literal meaning) from connotation (cultural associations). He argued photographs are 'messages without a code' yet laden with ideological connotations through techniques like pose, angle, and objects. The article uses a stop sign to illustrate how meaning depends on learned language, context, and audience. Peirce's categories overlap: analog film is both iconic and indexical, raising preservation issues for digital media. Barthes' analysis of a 2024 Trump photo shows how framing, angle, and symbols (raised fist, flag colors) convey power. The raised fist also echoes the 1968 Black Power protest, highlighting how signs can be appropriated across contexts.
