Pragmatics
 
The person could simply say, "Stop smoking, please!" which is a direct method and has clear semantic meaning. Alternatively, the person could say, "Whew, this room could use an air purifier" which implies a similar meaning but is indirect and therefore requires pragmatic inference to derive the intended meaning.
