Grammar and communication
although linguists may take particular notice of such features of a linguistic form, ordinary language users generally focus their attention on what is meant by the use of such forms, and this, as we have seen, involves taking context into account.
So another judgement that might be made about an instance of language use is whether and to what extent it is appropriate to its context. The issue here is not whether a piece of language is grammatically or lexically well formed as a sentence or not but how far it is pragmatically effective as an act of communication.
