Abstract
Often we mean something else than what we have said explicitly. Consider the following scenario. I show up in a new flashy dress and ask my friend what she thinks of it. She always tries to help me improve my style and knows that I value her honest opinion. She looks at my dress and says: ‘Excellent fit, but have you gone colour blind?’. From what she says I do not take it that she is interested in whether I’ve got a colour vision deficiency. Rather, I take her to mean that she does not like the colours of my dress. In this way we constantly communicate more than what our words say, or even something else than what we say. When we do so, we make use of a conversational tool which Paul Grice calls implicatures. His theory of such implicatures has been central for contemporary debates on the relation between semantics and pragmatics, and also that between logic and semantics. In this chapter we will look at the notion of implicatures in some detail.
