Denotation refers to the literal or primary meaning of a word, the explicit definition found in a dictionary, as opposed to its connotation, which includes the emotional or cultural associations it may evoke. For example, the denotation of the word "home" is a physical dwelling place, while its connotations might include warmth, safety, and family. Understanding denotation is essential for clear communication, ensuring that the intended meaning is conveyed without ambiguity.
