Conférence de Peter Gärdenfors
The meanings of words are not permanent but change over time. Some changes of meaning are quick, such as when a pronoun changes its reference ; some are slower, as when two speakers find out that they are using the same word in different senses ; and some are very slow, such as when the meaning of a word changes over historical time. A theory of semantics should account for these different time scales.
In order to describe these different types of meaning changes, I present an analysis of three levels of communication : instruction, coordination of common ground and coordination of meaning. My first aim is to show that these levels must be considered when discussing lexical semantics.
A second aim is to use the levels to identify the communicative roles of some of the main word classes, in particular nouns, adjectives, verbs, and indexicals. I argue that the existence of word classes can, to a large extent, be explained by the communicative needs that arise on the different levels.
