Introduction to Semantics in Linguistics: Key Concepts

Illustration demonstrating nuances of Semantics

Did you know the word "bank" could mean different things depending on how it is used?

It could mean a financial institution where you keep your money or valuable items, or it could also mean the land alongside a river, i.e. a river bank. This capacity of words which allows them to represent different things in different situations in called Polysemy.

Words can express meaning in many ways. A word can have multiple meanings, or it can share similar meanings with another word (synonymy), have an opposite meaning (antonymy), or share the same spelling or sound with a different word (homonymy). These properties of words show that meanings are not rigid or inherent, rather, they are associated on the basis of context. Semantics is the organised study of these meanings, the connections between them, and the interactions between words.

What Exactly Is Semantics?

In simple terms, semantics is the study of meaning in a language. It looks at the meanings of words, phrases, and sentences, and at the relationships between those meanings. The focus is on how meanings are associated with words in a language and how, in different sentences, the same word could mean an entirely different thing.

For example, consider the word "bright." In the sentence:

She has a bright lamp.

Here the word 'bright' refers to something that gives or reflects a lot of light. But in:

She is a bright student.

the word 'bright' describes the person's intelligence rather than light.

The word is the same but what it means in these two cases is entirely different. This shows that knowing an isolated dictionary definition does not necessarily mean that we now completely understand the meaning of the word.

Semantics asks us to look beyond the question "What does this word mean?" and consider questions such as:

• What different meanings can a word represent or have?
• How are those meanings related?
• How does the meaning of a word change when it appears in a different sentence?
• How are the meanings of different words related to one another?
• How do individual words combine to create the meaning of a sentence?

Ambiguity in Meaning

It is very common in languages like English for a sentence to have two or more possible meanings. This is called ambiguity.

Consider this sentence:

He was watching the man with the telescope.

There are at least two possible interpretations of this sentence.

1. Someone is watching someone using a telescope.
2. Someone is watching a person who is carrying a telescope.

The words themselves have not changed, but the relationship between them can be understood in different ways.

This is where semantics becomes particularly interesting. Human language gives us an enormous number of possible combinations, yet most of the time we understand what someone means without consciously analysing every possible interpretation.

How Do We Choose the Right Meaning?

Imagine someone says:

I went to the bank yesterday.

There are at least two possible meanings of bank. Either the person visited a financial institution, or they went to the land beside a river?

In most ordinary conversations, we would probably understand the intended meaning very quickly. Because meaning does not come from a single word alone. We use the context i.e. the surrounding words, our knowledge of the world, and the situation in which something is said to interpret the meaning of what is being said.

If the speaker continues:

I went to the bank yesterday and deposited some money.

This alleviates the confusion almost entirely. The chunk of words "deposited some money" provides a strong clue that the word "bank" here is referring to a financial institution.

But if the speaker says:

I went to the bank yesterday and sat there watching the water.

Here our brain is more likely to understand "bank" as the land beside a river or another body of water (but that is assuming the person knows the both meanings of the word 'bank').

It can be established now that our understanding of meaning is therefore not simply a process of looking up words in a mental dictionary. To properly understand a word, we must consider its context, which includes the words that surround it as well as the actual setting in which it was spoken.

Word-Word Relationships

In Semantics, one of the areas of interest is the relationship between words and how this relationship affects the meanings.

Consider:

big — large

These words have similar meanings. They are called synonyms or synonymous words.

Now consider the words:

hot — cold

These words have opposite or contrasting meanings. They are called antonyms or antonymous words.

Now consider:

rose — flower

A rose is a type of flower. This type/subtype relationship is called hyponymy. A hyponym is a subtype (more specific) of a major (more general) category hypernym. 'Dog' is a hyponym of a major category 'animal' and 'animal' is the hypernym for 'dog'.

And:

wheel — car

A wheel is a part of a car. This is a part–whole relationship, known in semantics as meronymy.

These relationships show us that vocabulary is not simply a long list of unrelated words rather words form networks where they are related somehow to other words in the same network.

Literal and Figurative Meaning

Another interesting area of meaning is the difference between literal and figurative language.

Consider:

He has a heart of stone.

We do not normally understand this sentence literally. The person's heart is not actually made of stone.

The sentence is figurative and suggests that the person is emotionally cold, unkind, or lacking sympathy.

English contains thousands of expressions like this:

She broke my heart.
He has a sharp tongue.
I'm drowning in work.

Understanding such expressions requires more than knowing the individual dictionary meanings of drowning, break, heart, or sharp. We need to understand how those words are being used together.

Why Is Semantics Important for English Learners?

For an EFL or ESL learner, semantics is not simply an abstract area of linguistics. It can help explain many difficulties that learners experience when learning English.

For example, a learner may know that look, see, and watch are connected with vision, but knowing their dictionary meanings does not automatically tell them when to use each one.

Compare:

- I saw a bird.
- I watched the bird.
- I looked at the bird.

The three verbs are related, but they represent different ways of experiencing or directing attention towards something.

Studying semantics helps learners notice these differences and understand why one apparently similar word sounds natural in a particular sentence while another does not.

Does Correct Grammar Guarantee Meaninful Language?

Semantics challenges a common misconception that correct grammar is an absolute criteria for a meaningful sentence. A sentence could be grammatically sound but it deoesn't automatically make it a meaningful sentence. Consider the examples:

- Two and two make fifteen.
- Colourless green ideas sleep furiously.
- The door is opening the boy.

All of the sentences above are grammatically correct but they are illogical and meaningless. In reality, two and two do not make fifteen. If something is 'colourless' it cannot be green. Sleep is an indication of rest, a complete opposite of furiosity. Usually, people open the doors, not the other way around.

These examples prove that to produce meaningful language, we do not just have to pay attention to grammar but also need to make sure that the chosen words are not contradictory or illogical.

In a Nutshell

Semantics is the branch of linguistics concerned with meaning.

It studies the meanings of words, phrases, and sentences, as well as relationships such as similarity, contrast, part–whole relationships, and category relationships.

It also helps us understand that grammar is not enough for producing meaninful language and why the same word can represent different things, why some sentences can have multiple interpretations, and how individual words combine to create larger meanings.

So the next time you encounter a word such as bank, light, head, or run, do not simply ask:

"What does this word mean?"

Ask something more interesting:

"What meaning does this word represent here, and how do I know?"

That question takes you directly into the world of Semantics.
