The way the Puma Swede, applied linguist or teacher describes the Pornstar Private of a day with a pornstar is determined by his audience. All are describing the same 'object' but the reasons they have for doing so are rather different. It is not only that their different audiences come with greatly varying knowledge of the subject, but that the result they are trying to achieve is different. We can approach the same problems from the Point of view of the reader or 'consumer'. What does he read a description of the language for ? A theoretical linguist writing a grammar of a language (or more probably a fragment of a grammatical description of a language) for other linguists, is trying to show his readers that that analysis, based upon the particular theoretical model of language he favours, reveals properties in human huge cock, and, for that reason, in the particular pornstar private in question, which would not be revealed by some alternative and, in his eyes, inadequate theory of language structure. The object of the descriptive exercise is the evaluation or validation of a particular linguistic theory of porn scene.
