lexical item In lexicography, a lexical item is a single word, a part of a word, or a chain of words ( catena) that forms the basic elements of a language's lexicon (≈ vocabulary). Examples are ''cat'', ''traffic light'', ''take care of'', ''by the way' ...
that is associated with affirmation or negation. An affirmation is a positive polarity item, abbreviated PPI or AFF. A negation is a negative polarity item, abbreviated NPI or NEG. The linguistic environment in which a polarity item appears is a licensing context. In the simplest case, an affirmative statement provides a licensing context for a PPI, while negation provides a licensing context for an NPI. However, there are many complications, and not all polarity items of a particular type have the same licensing contexts.


In English

As examples of polarity items, consider the

lexical items ''somewhat'' and ''at all'', as used in the following sentences: # I liked the film somewhat. # I didn't like the film at all. # *I liked the film at all. # *I didn't like the film somewhat. As can be seen, ''somewhat'' is licensed by the affirmative environment of sentence (1), but it is forbidden (anti-licensed) by the negative environment of sentence (4). It can therefore be considered to be a positive polarity item (PPI). On the other hand, ''at all'' is licensed by the negative environment of sentence (2), but anti-licensed by the positive environment of sentence (3), and is therefore considered a negative polarity item (NPI). Because standard English does not have negative

s are not used to intensify each other, the language makes frequent use of certain NPIs that correspond in meaning to negative items, and can be used in the environment of another negative. For example, ''anywhere'' is an NPI corresponding to the negative ''nowhere'', as used in the following sentences: # I was going nowhere. (the negative ''nowhere'' is used when not preceded by another negative) # I was not going anywhere. (the NPI ''anywhere'' is used in the environment of the preceding negative ''not'') Note that double-negative constructions like ''I was not going nowhere'' take on an opposing meaning in formal usage, but that this is not necessarily the case in colloquial contexts and in various

s, which parallels other languages which have negative concord. ''Anywhere'', like most of the other NPIs listed below, is also used in other senses where it is not an NPI, as in ''I would go anywhere with you''. *nobody/no one – anybody/anyone *nothing – anything *no/none – any *never – ever *nowhere – anywhere *no longer/no more – any longer/any more See also , and .


Determination of licensing contexts

The actual set of contexts that license particular polarity items is not as easily defined as a simple distinction between affirmative and negative sentences. Baker noted that
double negation In propositional logic, double negation is the theorem that states that "If a statement is true, then it is not the case that the statement is not true." This is expressed by saying that a proposition ''A'' is logically equivalent to ''not (not ...
may provide an acceptable context for positive polarity items: : I can't believe you don't fancy her somewhat. : John doesn't have any potatoes : *John has any potatoes. However, licensing contexts can take many forms besides simple negation/affirmation. To complicate matters, polarity items appear to be highly idiosyncratic, each with its own set of licensing contexts. Early discussion of polarity items can be found in the work of

environments. This is known as the Fauconnier–Ladusaw hypothesis. A downward entailing environment, however, is not a necessary condition for an NPI to be licensed—they may be licensed by some non-monotone (and thus not downward entailing) contexts, like "exactly N," as well. : *Some people have ever been on the moon. : Exactly three people have ever been on the moon. Nor is a downward entailing environment a sufficient condition for all negative polarity items, as first pointed out by Zwarts (1981) for Dutch "ook maar." Licensing contexts across languages include the scope of n-words (negative
