Words have meaning.
They tell us about things. A word can point to a real thing. It can also be an idea in your head. This helps us talk to each other. It is how we share our thoughts.

Words have meaning.
Semantics is the study of that meaning. It looks at how words work. It also looks at how sentences work.
One word can point to a real thing. This is called a reference. A word can also be an idea. This is called a sense. You can learn new meanings by joining words together. This helps us understand many new things. It is a big part of how we talk.
Studying meaning helps us understand our world.
What does a word mean?
Semantics is the study of meaning in language. It looks at how words and sentences work. It also looks at how we get meaning from them.
Some people study word meaning. This is called lexical semantics. Other people study how sentences work. This is called phrasal semantics. This uses a rule called compositionality. This rule says that sentence meaning comes from its parts. It is how we understand new sentences every day.
Semantics also looks at sense and reference. A reference is the real object a word points to. A sense is the idea or concept in your mind. For example, "morning star" and "evening star" point to the same planet. But they have different senses.
Semantics is different from syntax. Syntax is the set of rules for making correct sentences. It is also different from pragmatics. Pragmatics is how people use language in real life. Semantics focuses on the general meaning of words. This is often the same meaning you find in a dictionary. The study of semantics became its own field in the 19th century. A man named Michel Bréal helped start it.
Have you ever wondered how a word connects to a real thing?
Semantics is the special study of meaning in language. It looks at how words and sentences work together. It also looks at how we understand the ideas they carry. This field helps us see how language relates to the world. It explores how we get meaning from different layers of speech.
This includes everything from small parts like morphemes to whole texts.
One way to understand meaning is through sense and reference.
A reference is the actual object that a word points to. The sense is the idea or concept in your mind. For example, the "morning star" and "evening star" both point to the same planet. They have the same reference, but they have different senses. This helps explain how two different phrases can mean the same thing. Understanding both the object and the idea is very important.
Meaning also works through a rule called compositionality.
This is part of phrasal semantics, which studies sentence meaning. It says that the meaning of a big sentence comes from its parts. You can understand "Zuzana owns a dog" by knowing each word. This rule helps us understand almost infinite new sentences every day. Even if you have never seen a sentence before, you can grasp it. It uses the words and the way they are arranged.
Semantics has a long and interesting history. People have studied meaning since ancient times. However, it did not become its own field until the 19th century. The word comes from a Greek word meaning "relating to signs."
A man named Michel Bréal first used it in English. He was a linguist who helped define the term. Before this, the word was sometimes used for medical symptoms. Now, it is a major part of linguistics and philosophy.
Semantics is different from other parts of language study. Syntax focuses on the rules for making correct sentences. Phonology looks at the different sounds we use to speak. Pragmatics is how people use language in real life. For example, a phrase can mean different things in different situations.
Semantics stays focused on the general, dictionary-style meaning. It looks at what words can mean in a general way. This helps us separate the words themselves from how people use them.
Semantics is the systematic study of linguistic meaning. It investigates how meaning arises within a language and how it functions. This field examines how expressions are built from various layers of constituents. These layers include morphemes, words, clauses, sentences, and even full texts. Researchers look at how the meanings of these smaller parts affect one another. By doing so, they seek to understand the very nature of communication.
Semantics is a descriptive discipline. This means it aims to determine how meaning actually works. It does not try to prescribe how people should use words. Instead, it asks how words combine to create the meaning of sentences. It also explores the connection between words, the mind, and the physical world.
To understand semantics, one must distinguish it from other linguistic fields. Syntax is the study of rules for arranging words into correct sentences. Phonology examines the different sounds used in a language and how they form words. Semantics is also different from pragmatics. Pragmatics investigates how people use language in specific communication contexts. For example, the phrase "That's what I'm talking about" changes meaning based on the situation. While pragmatics looks at actual performance and context, semantics focuses on context-independent meaning. This is the general, public meaning often found in dictionary definitions.
Semantics is a subfield of semiotics. Semiotics is the broader study of both linguistic and non-linguistic signs. This includes things like nodding to show agreement or stripes on a uniform. Semantics focuses specifically on the meaning within human language.
Meaning can be analyzed through several distinct branches. Lexical semantics is the study of individual word meanings. It examines if words have one or many meanings and how they relate to each other. Phrasal semantics studies the meaning of full sentences. It often explores compositionality, which is how new meanings emerge from word arrangements. Formal semantics uses logic and mathematics to create precise frameworks for meaning. Cognitive semantics takes a psychological approach. It assumes language is closely related to the mental structures we use to understand the world. Other specialized branches include computational, conceptual, and cultural semantics.
A central concept in this field is the distinction between sense and reference. This idea was first introduced by the philosopher Gottlob Frege. The reference, or referent, is the actual object in the world that an expression points to. The sense is the way that object is interpreted or the idea associated with it. For example, the "morning star" and the "evening star" both point to the same planet. They share a reference, but they possess different senses. This distinction explains why the sentence "the morning star is the evening star" is informative. It allows us to learn that two different descriptions actually describe the same thing.
Another vital mechanism is the principle of compositionality. This principle suggests that the meaning of a complex expression is a function of its parts. For instance, you can understand "Zuzana owns a dog" by knowing the meanings of the individual words. This process allows humans to understand an almost infinite number of meanings. Even if you encounter a sentence you have never seen before, you can often grasp it. This happens because you understand the constituent parts and how they are combined.
While some scholars debate the strength of this principle, it remains a key way to explain linguistic competence.
Various theories attempt to explain how expressions are endowed with meaning. Referential theories suggest meaning is simply the part of reality an expression points to. Ideational theories identify meaning with mental states, such as the ideas an expression evokes. Causal theories argue that meaning is determined by causes and effects. Behaviorist semantics analyzes this through the lens of stimulus and response. Other frameworks include truth-conditional semantics and verificationist theories. These different perspectives help researchers approach the complex relationship between language and thought from multiple angles.
The history of semantics shows it has been studied since antiquity. However, it was not recognized as an independent field until the 19th century. The word itself comes from the Ancient Greek adjective *semantikos*, meaning "relating to signs." Originally, the term was used to describe medical symptoms. It later expanded to include all types of signs, including linguistic ones. The linguist Michel Bréal introduced the term into the English language from French. Today, semantics is essential to many fields. It connects deeply to formal logic, computer science, and psychology. It also relates to etymology, which tracks how word meanings change over time.
