A word seems like a stable unit until it enters a conversation. There, it changes direction, acquires a different nuance, or produces a different meaning. We call this phenomenon polysemy: the capacity of the same linguistic expression to develop several related senses.
Although it reveals the richness of vocabulary, it also draws meaning out of the word itself. The word becomes a projector of possibilities, whose relevance is filtered through context. Outside a communicative situation, without other interrelated words, stripped of context, without the shared knowledge of the participants in the communicative act, and without interpretation, the word is not polysemous. Merely semous, perhaps?
Some senses become conventionalized over time, while others depend more heavily on the situation. Polysemy makes language less like a dictionary and more like a territory, with history and movement. Each new use can expand the family of meanings that a word is capable of evoking.
Could polysemy be the mechanism language uses to let us know that it is alive?
