Unveiling the Hidden: A Dive into Texts and Sign Studies

Every time you see a red heart emoji, hear a funeral march, or glance at a “green means go” traffic light, you are decoding signs – often without realizing it. This act of interpretation sits at the core of semiotics, the study of signs and the meanings they carry. Far from being a narrow linguistic exercise, semiotics examines how meaning is produced and communicated across everything from spoken words and written texts to photographs, gestures, music, and even the clothes we wear. For students of journalism and mass communication, it is an indispensable lens for understanding how media messages are constructed, what they really say, and whose interests they serve.

What is semiotics?

Semiotics is the study of signs and their meanings in society – where a sign is anything capable of conveying meaning. The term itself comes from the Greek semeion, meaning “sign.” It explores the relationships between signs, including talk and text, and their intended specific meanings. In practice, this means that a stop sign, a national flag, a film score, a corporate logo, or a social media post are all legitimate objects of semiotic study.

The field emerged independently through two foundational thinkers working at roughly the same time in the early twentieth century: Ferdinand de Saussure (1857-1913), a Swiss linguist, and Charles Sanders Peirce (1839-1914), an American philosopher. Their approaches are not only confined within their respective areas of study but have produced significant impacts across disciplines including arts, literature, music, theatre, film, advertising, anthropology, architecture, and communication.

What exactly is a “text” in semiotics?

In everyday language, a “text” usually means written words on a page. In semiotics, the concept is far broader. Semioticians study how signs combine to form larger expressions called texts, and they explore how the message of a text depends on the meanings of the signs that compose it and on contextual factors. A text, in this sense, is not merely a novel or a news article. It can be a film, a diagram, a poster, a musical composition, a fashion outfit, or even a television advertisement.

What distinguishes a text from a random collection of signs is organisation. The meaning of a text – its message – is shaped not just by the individual signs within it but by how they interact with one another. In addition to linguistic texts such as a novel or a mathematical formula, there are also non-linguistic texts such as a diagram, a poster, or a musical composition. Crucially, the meaning of a text can also depend on and refer to other texts – a feature semioticians call intertextuality.

For journalism and media students, this expanded definition of “text” is powerful. It means that a news broadcast, a campaign poster, or an Instagram reel can all be “read” and analysed the same way you would read a written article – by examining the signs it deploys and the meanings those signs carry.

The building blocks: signifier and signified

Saussure’s central contribution was breaking down the sign into two inseparable parts. In his 1916 Course in General Linguistics, Saussure divided the sign into the signifier (the sound-image or material form) and the signified (the concept or meaning it represents). The word “tree,” for instance – its spoken sound or written letters – is the signifier, while the mental concept of a tree is the signified. Crucially, the meaning of a sign depends on its relation to other words within the system; to understand “tree,” you must also understand how it differs from “bush” or “shrub.”

One of the most important implications of Saussure’s model is the principle of arbitrariness: there is no natural or necessary connection between a signifier and its signified. The word “cat” does not resemble a cat in any way – the link is purely a social convention. The meanings attached to signs are not inherently linked to their physical form but are instead determined by cultural conventions and social agreements. This is why the same object can have entirely different names – and different meanings – across different languages and cultures.

Peirce’s three types of signs

Where Saussure focused on language, Peirce cast a wider net. He proposed that all signs could be categorised into three types based on how they relate to what they represent:

Icon: A sign that resembles what it stands for. A photograph of a person is an iconic sign. So is a map or a realistic portrait.
Index: A sign with a direct, causal link to what it represents. Smoke is an index of fire. A weather vane is an index of wind direction. Most traffic signs are index signs, as they represent information directly related to a physical location or condition.
Symbol: A sign with no logical or visual resemblance to what it represents – the connection is entirely conventional. A national flag, a written word, or a corporate logo are symbols. Their meanings are learned, not inherent.

Peirce viewed the symbol/index/icon triad as “the most fundamental division of signs,” and the majority of semioticians continue to agree. This triad is now used across disciplines well beyond linguistics – from film theory to interface design to advertising analysis.

According to Peirce, signs take the form of words, images, sounds, odours, flavours, acts or objects – but such things have no intrinsic meaning and become signs only when we invest them with meaning. “Nothing is a sign unless it is interpreted as a sign,” Peirce argued. This interpretive dimension places the reader, viewer, or listener at the very centre of the meaning-making process.

Barthes and the layers of meaning

Building on Saussure’s foundations, the French critic Roland Barthes expanded semiotics into the realm of culture and ideology. His key contribution was the distinction between denotation, connotation, and myth.

Denotation and connotation

Barthes divides the meaning of signs into three levels: denotation (the literal or direct appearance), connotation (the additional meaning shaped by culture and emotion), and myth (the ideological narrative that renders certain meanings as natural). Denotation is straightforward – a photograph of a rose denotes the flower itself. Connotation is where culture steps in: that same rose connotes romance, love, or passion in many Western contexts. A photograph of a young man might denote simply “a young man,” but it might connote youthfulness, energy, or even rebellion, depending on the cultural context.

The concept of myth

Barthes argued that in modern society, signs do not merely convey simple, literal meanings but are loaded with additional cultural and ideological meanings, which he called “myth.” In Barthes’ use of the term, myth does not mean a fairy tale or fiction. It refers to the way certain cultural meanings are made to appear natural, universal, and inevitable – even though they are historically and socially constructed.

His most famous example involved a magazine cover showing a young Black soldier saluting the French flag. Barthes felt the image signified “France is a great empire” and that all her sons, without colour discrimination, faithfully serve under her flag. The photograph, far from being a neutral image, was a cultural and political statement – one designed to naturalise the ideology of French imperialism. In his highly regarded book Mythologies, Barthes sought to decipher the cultural meaning of a wide variety of visual signs – from sweat on the faces of actors in a film to advertisements for cars and household goods.

The lesson for media students is significant: cultural texts such as commercials, videos, film, television, and music are not merely entertainment – they dissect the underlying semiotic structures of everyday objects and rituals, revealing how they reflect and reinforce societal values and ideologies.

Non-verbal signs: images, sounds, and symbols

One of semiotics’ most important contributions to communication studies is its insistence that meaning is not confined to language. Semiotics helps people think deeply about the meaning attached to colors, images, sounds, and events, and to consider how perceptions may have been predetermined by external factors.

Consider colour. Black is conventionally worn for mourning in most Western countries, yet in parts of South Asia and East Asia, white is the colour of mourning. Neither connection is natural – both are cultural codes. In advertising, colour choices are deliberate semiotic decisions. Red communicates urgency or passion; blue signals trust and stability. These are not universal truths – they are learned conventions that vary across cultures and contexts.

Sound operates similarly. The horror genre relies heavily on discordant strings or sudden silence to signal danger before it arrives on screen. A news broadcast’s authoritative anchor voice, its formal setting, and its visual layout all work together as a system of signs constructing credibility and trustworthiness. We cannot fully make sense of signs without taking into account the context – signs, how they operate and how they relate signifier to signified, take place within systems called codes.

Semiotics and codes in media

Signs do not operate in isolation. They work within shared systems of convention that semioticians call codes. A code is an agreed-upon set of rules for interpreting signs within a specific cultural or social context. Genre conventions in film are codes – audiences know that a certain type of music, lighting, and editing signals “thriller” rather than “romantic comedy.” News photography has its own codes: certain framings, angles, and caption styles signal objectivity, while others signal opinion or advocacy.

Semiotics operates within two primary frameworks: first, exploring the relationship between a sign and its meaning, and second, investigating how signs combine to create broader cultural meanings. When a news organisation chooses which images accompany a story about crime, poverty, or immigration, those choices are not neutral. They are semiotic decisions that activate codes, trigger connotations, and shape how audiences understand the issue. Unpacking those choices is precisely what semiotic analysis in journalism is designed to do.

Semiotics is a method for exposing and studying mass media, literary texts, and systematically analysing various aspects of popular culture. In doing so, it enables researchers, journalists, and communicators to ask not just “what does this message say?” but “how does it say it, for whom, and in whose interest?”

Why semiotics matters for communication research

Semiotics fosters a deeper appreciation of cultural diversity by discerning subtle nuances in communication and the social construction of the language and symbols we frequently deploy. For communication researchers, this matters enormously. A semiotic analysis of a political advertisement, for instance, can reveal the ideological assumptions baked into its imagery, word choice, and sound design – layers of meaning that a purely content-based analysis would miss.

Semiotics can help understand why certain signs are interpreted differently in different cultures and different geographies. For instance, the American “OK” hand sign may be considered rude in Brazil, while symbols of national pride in one country may carry colonial overtones to another. These cross-cultural semiotic mismatches are not trivial – in journalism, diplomacy, and global marketing, they have real consequences.

The scope of semiotic research continues to expand. The field of media semiotics studies how meaning is produced, interpreted, and shared in media including newspapers, radio, television, and the internet, and encompasses all channels of everyday communication. From decoding a meme to analysing a government press release, semiotic tools give communication scholars a systematic method for reading beneath the surface of any message.

What do you think? When you watch a news programme or scroll through social media, are you aware of the visual and verbal choices being made – and the meanings they are quietly constructing? And if signs always depend on cultural codes to be understood, what happens to communication when the sender and receiver do not share the same cultural background?
