Dijkhoff (1993: 93–96) provides an overview of reduplication in Papiamentu. Productive reduplication is largely restricted to adjectives and adverbs, expressing intensification. In addition, plural reduplication of nouns is attested (see Feature 23 "Expression of nominal plural meaning"); perhaps more frequently, noun reduplication occurs with denominal adverbial or adjectival functions.
Also, Dijkhoff provides two examples of iterative verb reduplication. Finally, there's a small number of reduplicated lexicalized deadjectival, deverbal, and denominal nouns.
