Words can have more than one meaning, sometimes several, depending on the context in which they are used.

The denotative sense is also called the literal meaning of the word, that is, it has the original interpretation.

Example: The sun is hot.

The word sun was used in its literal sense, a star of the solar system.

Example: You are my sun.

Here the word sun was employed with a connotative sense in an affectionate statement.
