Negative polarity items are licensed 'in the scope' of their trigger.
In this article, I take a closer look at the relevant notion of scope,
which is shown to involve syntactic, semantic and pragmatic considera
tions. In general, a position in the c-command domain of its trigger a
t S-structure is sufficient for an NPI to be licensed. If the NPI prec
edes its trigger, the sentence is felicitous only if the NPI can be in
terpreted in the semantic scope of its trigger. The possibility of an
inverse scope reading of negation is subject to a pragmatic constraint
, which requires the sentence to convey positive information. The inca
pability of bare NPIs involving any in English or ook maar in Dutch to
satisfy this constraint explains why they cannot precede their trigge
r. Embedded NPIs and the NPI hoeven 'need to' in Dutch can satisfy the
pragmatic constraint on inverse scope, and are therefore licensed out
side of the c-command domain of the trigger.
