Semantics is the study of meaning. This can include the meaning of individual words‏‎ and also the way in which their meaning may have changed over time.

Meaning in languages is mainly studied by linguists. In fact, semantics is one of the main branches of contemporary linguistics. But there are also strong connections to philosophy. In the last century much work in semantics was done by philosophers, and some important work is still done by philosophers.

An understanding of semantics is essential to the study of language acquisition‏‎, that is, the study of how language users – be they speakers, writers, listeners or readers – acquire a sense of meaning. It also helps us focus on how language develops and changes with time.

Semantics is one of the most fundamental concepts in linguistics. It is important for understanding:

  • language in social contexts
  • varieties of English‏‎
  • effects of style

The study of semantics includes the study of how meaning is constructed, interpreted, clarified, obscured, illustrated, simplified negotiated, contradicted and paraphrased.


Semantics is also about relationships. Look at these sentences:

Mo ate a fish.

A fish ate Mo.

The two sentences have identical words but the meaning has changed because of the order in which the words were used. So the grouping of words can change the meaning of a sentence, not just the words used in the sentence.

Words in Semantics

But semantics is also about words themselves and even breaking them down into their elements. We have the following words in English:



So what is the meaning of the -ish affix? We also can ask what is the meaning of the -ly affix here:



Semantic Fields

When a group of words relate to the same topic or subject, we have asemantic field.

boring, dull, tiresome, banal…

house, cabin, hovel, mansion…
