Overview
Every media product is made up of signs — images, words, colours, camera angles, gestures — that combine to produce meaning. Semiotics is the study of how those signs work.
Roland Barthes, building on the linguist Ferdinand de Saussure, argued that a sign is never neutral. Nothing in a media text is there by accident: every choice is loaded with meaning that a reader has to actively decode.
Barthes' model gives you the vocabulary to move beyond "what's in the image" and into "what it's really saying" — and it applies just as well to a bomb-disposal drama as it does to a magazine cover.
Key Ideas
The Sign: Signifier and Signified
Barthes' basic unit of meaning is the sign, which is made up of two parts:
- Signifier — the physical form of the sign: the actual word, image, sound or object.
- Signified — the mental concept it triggers in the reader's mind.
Put a signifier and a signified together and you get a sign. A red rose (signifier) triggering the idea of romance (signified) is a sign of love.
Denotation and Connotation
- Denotation — the literal, obvious meaning of a sign: what it actually shows.
- Connotation — the associated, cultural meaning a sign carries beyond its literal content.
A pair of glasses denotes an object worn on the face to correct vision. It can connote intelligence, studiousness, or vulnerability, depending on the context and codes around it.
Myth
Barthes used the term myth to describe connotations that have become so naturalised through repetition that audiences accept them as "common sense" rather than as constructed meaning. A myth makes something that is cultural (produced by a particular society, ideology or history) appear natural and unquestionable.
For example, the myth that a strong jawline and stubble connote masculine authority is not natural — it is a connotation built up through decades of repeated media representation, but it is often read as if it were simply "how things are".
Anchorage and Polysemy
- Polysemy — an image on its own can carry multiple possible meanings.
- Anchorage — accompanying text (a caption, a headline, dialogue) narrows down and fixes one preferred meaning, steering the reader away from other possible readings.
Applying the Theory: Trigger Point (Series 2, Episode 1)
Worked example — read this through before the quiz.
The text
Trigger Point (ITV) follows Lana Washington, an EXPO (bomb disposal officer) in the Metropolitan Police and an Afghan War veteran. In the Series 2 opener, Lana has just returned from a secondment training bomb disposal teams abroad and has not yet returned to active duty. While giving a talk to security officers, an explosion hits a power plant in the city, pulling her straight back into frontline work under a new, more dismissive boss.
Applying Barthes
Lana's protective suit and equipment are signifiers that denote bomb-disposal gear. Their connotation is danger, precision and technical expertise — codes usually associated with action-hero masculinity in crime drama, so applying them to a female lead disrupts the expected sign system.
The low-key lighting and night-time skyline are signifiers that denote a dark, empty cityscape. They connote threat, isolation and moral ambiguity — genre-typical crime-drama codes that anchor the audience's expectations before any dialogue is spoken.
The myth at work here is the naturalised idea that authority and danger belong to men: by placing a woman at the centre of these signs without comment, the text quietly challenges that myth rather than stating the challenge outright. The dismissive new boss functions as anchorage — his dialogue narrows the polysemy of the earlier images, fixing a preferred reading that his attitude is outdated rather than normal.
Myth and Anchorage in Practice
Barthes' idea of myth is easiest to spot when you ask what a sign makes you assume is "just natural" — and then ask where that assumption actually comes from.
Worked example
A magazine cover showing a well-dressed man gazing confidently into the distance denotes a man in a suit looking away from the camera. It connotes success, ambition and control. The myth this supports is that visible wealth and physical poise are natural markers of male achievement — a connotation repeated so often across advertising and editorial media that audiences rarely question it.
A coverline such as "The Man Who Has It All" is an example of anchorage: without it, the image alone is polysemic (he could be lost, waiting, distracted) — the words fix one preferred reading and shut down the others.

The Poster: Trigger Point (Series 2)
Use this image for your homework task. Identify 4 different signs (items of iconography) on the poster. Your annotations go on your OneNote homework page, not here — for each sign, name what it literally shows (denotation) and explain what it culturally suggests to the audience (connotation), then note any myth the connotation supports.
