negation (n.)

A process or construction in GRAMMATICAL and SEMANTIC analysis which typically expresses the contradiction of some or all of a sentence’s meaning. In English grammar, it is expressed by the presence of the negative particle (neg, NEG) not or n’t (the CONTRACTED negative); in LEXIS, there are several possible means, e.g. PREFIXES such as un-, non-, or words such as deny. Some LANGUAGES use more than one PARTICLE in a single CLAUSE to express negation (as in French ne . . . pas). The use of more than one negative form in the same clause (as in double negatives) is a characteristic of some English DIALECTS, e.g. I’m not unhappy (which is a STYLISTICALLY MARKED mode of assertion) and I’ve not done nothing (which is not acceptable in STANDARD English).

A topic of particular interest has been the range of sentence STRUCTURE affected by the position of a negative particle, e.g. I think John isn’t coming v. I don’t think John is coming: such variations in the SCOPE of negation affect the logical structure as well as the semantic analysis of the sentence. The opposite ‘pole’ to negative is POSITIVE (or AFFIRMATIVE), and the system of contrasts made by a language in this area is often referred to as POLARITY. Negative polarity items are those words or phrases which can appear only in a negative environment in a sentence, e.g. any in I haven’t got any books (cf. *I’ve got any books).
