4.1 Dennotation

This is the core or central meaning of a word or lexeme, as far as it can be described in a dictionary. It is therefore sometimes known as the cognitive or referential meaning. It is possible to think of lexical items that have a more or less fixed denotation (sun, denoting the nearest star, perhaps) but this is rare. Most are subject to change over time. The denotation of silly is not today what it was in the 16th century, or even the 18th, when Coleridge referred to the silly buckets on the deck. Denotation is thus related to connotation, which leads to semantic change.
