Examples and Observations:

• Two Types of Sentence Negation
  "It is usual to distinguish between two types of non-affixalsentence negation in English: firstly, negation with not or -n't; and secondly, negation with the negative words never, neither, nobody, no, none, nor, nothing and nowhere. Tottie (1991), for example, terms the first type 'Not-negation' and the second type 'No-negation.' Quirk et al. (1985: 782) give a list of the negative words together with their corresponding non-assertive forms, pointing out that there are two negative equivalents for a positive sentence containing an assertive form: thus We've had some lunch has the two negative forms We haven't had any lunch and We've had no lunch (Quirk et al. 1985: 782). In the same way, these authors tell us, He sometimes visits us has the two negative forms He doesn't ever visit us and He never visits us."

• Exclamative Sentence Negation
  "In adult colloquial English, exclamativesentence negation can be defined as the combination of an idiomatic word or phrase, e.g., No way, like hell, the hell, yeah right, my eye, bullcookies, nonsense, with a sentence . . ., e.g., Like hell Al and Hilary are married, Al and Hilary are married, my eye."
