At is most fundamental level, Pragmatics is the study of utterances. Where Semantics is the study of sentences (special kinds of utterances) that are ordered by truth relationships, Pragmatics studies communication - those utterances that
do things, are context based, and discourse dependent.
There are lots of sentences that aren't utterances, but their truth cannot be assessed. For example, I went to buy a cup of coffee yesterday. I know the barista (B), so we chatted for a minute. Here's the reconstructed transcript:
ReplyDeleteB: (1)Hi, Wanda!
W: (2)Hi, Betty!
B: (3)How are you?
W: (4)Good - just working on my qualifying paper.
B: (5)Oh, hows it going?
W: (6)Meh - I'm having some data collection problems... Anyhow...
In this while dialogue, only sentences (4) and (6) have any kind of truth-valuable sentence, the rest are just utterances. If truth means "we know what the world would have to look like for it to be true", then "Hi, Wanda" means nothing - it tells us nothing about the world. But, this is still a valid part of linguistics that needs to be analyzed, and that is what Pragmatics can do - analyze sentences like this. "How are you?" is still serving some kind of pragmatic function - a theory we will have to develop.
