Sign (semiotics) facts for kids
A sign is anything that helps us understand something else. It's like a clue that gives us meaning. For example, a word is a sign because it tells us about an idea or object. A red traffic light is a sign that tells drivers to stop. Signs can be things we see, hear, touch, smell, or taste.
Scientists who study signs, called semioticians, have different ideas about how signs work. Two main theories help us understand this.

Saussure's Idea of Signs
Ferdinand de Saussure was a linguist who studied language. He thought that a sign has two main parts:
- The signifier (say: sig-nuh-FY-er) is the physical form of the sign. This could be a sound, a word written on paper, or an image.
- The signified (say: sig-nuh-FYD) is the idea or meaning that the signifier brings to mind.
Think of the word "tree." The sounds we make when we say "tree" (or the letters T-R-E-E) are the signifier. The image or idea of a tall plant with a trunk and branches in your mind is the signified.
Saussure believed that the connection between the signifier and the signified is mostly arbitrary. This means there's no natural reason why the word "tree" means a tree. We just agree as a society that it does. In other languages, a tree is called something completely different, like "arbol" in Spanish. This shows that the link is made up by people, not by nature.
Peirce's Idea of Signs
Charles Sanders Peirce was another important thinker who had a different view. He thought signs were more complex, involving three parts instead of two:
- The sign (or representamen) is the physical thing itself. This is similar to Saussure's signifier.
- The object is the real-world thing or idea that the sign refers to.
- The interpretant is the meaning or understanding that someone gets from the sign. It's how the sign is understood in a person's mind.
Imagine you see smoke.
- The smoke itself is the sign.
- The fire that caused the smoke is the object.
- Your thought, "There's a fire nearby!" is the interpretant.
Peirce also said that signs can be grouped into three types based on how they connect to their object:
Types of Peirce's Signs
- Icons: These signs look like or resemble what they represent.
- For example, a photograph of your friend is an icon of your friend. A map is an icon of a place.
- Indices: These signs have a direct connection to their object, like cause and effect.
- For example, smoke is an index of fire. A footprint is an index of someone walking there. A symptom (like a cough) is an index of a sickness.
- Symbols: These signs get their meaning from rules, habits, or agreements in society. There's no natural resemblance or direct connection.
- For example, words are symbols. The word "stop" doesn't look like stopping, but we all agree it means that. Traffic lights are also symbols.
Peirce believed that understanding signs is a continuous process. One sign can lead to another interpretant, which then becomes a new sign, and so on. This process of making meaning is called semiosis.
How We Understand Messages
When someone sends a message, like writing an article or speaking, how well it's understood depends on what the sender knows. If the sender doesn't know the language or culture well, the message might not be clear.
Modern ideas about signs suggest that meaning isn't just in individual signs. It's also in the context (the situation around the sign) and all the possible meanings that could apply. Language is like a huge memory of how people have communicated over time.
When you read or hear a message, your mind tries to figure out what it means. You use your own experiences and knowledge. Sometimes, a sign can have many possible meanings. Your brain then tries to find the best fit. If it's hard to tell, you might keep an open mind or guess a temporary meaning. Often, people quickly decide on a simple meaning, even if it's not exactly what the sender intended.
Signs in Modern Thinking
In more recent ideas, especially in critical theory, some thinkers believe that the connection between the signifier (the word or image) and the signified (the meaning) can become completely separated.
Floating Signifiers
A floating signifier is a sign that has a very unclear, changing, or even missing meaning. These signs can mean different things to different people. They might stand for many ideas, or whatever someone wants them to mean. For example, the word "freedom" can mean very different things to different people, depending on their experiences and beliefs.
