Schwegler (1991) and Dieck (2000, 2002) show that Palenquero grammar has three predicate negation structures, and that their behaviour is not directly related to the presence or absence of emphasis or commands. These negation structures are:
1. Strictly preverbal negation:
nu V (….)
2. Double (discontinuous) negation:nu V (….) nu
3. Postverbal (clause- or sentence-final) negation:
V (….) nu
The first two patterns also occur in other Afro-Hispanic regions of the Americas, including the Dominican Republic, Western Colombia (Pacific Lowlands), and Cuba (Schwegler 1996). Curiously, Costeño Spanish (northern Colombia) only has the Standard Spanish preverbal pattern. The double (but not the strictly postverbal) negation pattern does, however, occur in the Spanish of (some) Palenqueros (Schwegler & Morton 2003).
There is no agreement among specialists as to just exactly leads speakers to select a given pattern. Schwegler (1996) suggests that pragmatic factors (presuppositions) condition pattern selection. Dieck (2000, 2002) disagrees, citing semantic context and morphosyntactic criteria as primary causal determinants.
In terms of overall behaviour and use, the Palenquero negation patterns are very similar to those of popular Brazilian Portuguese:
- não falo
- falo não
- não falo não
where the three strategies are found (here too, the postverbal NEG occurs in clause- or sentence-final position).
