In a combination of ethnohistorical records and longitudinal data gath
ered over a period of 30 years, the development of Solomon Islands Pij
in is documented and analyzed in light of the current debate surroundi
ng creolization theory. Using a pragmatic definition of a creole (Jour
dan 1991), the authors argue that pidgins can be very elaborate codes
even before they become the mother tongue of children, and that this e
laboration is the result of the linguistic creativity of adults. It is
further shown that, in sociolinguistic niches where adults and childr
en use the pidgin as their main language, the impact of the latter on
the evolution of the language is of a different nature. (Creolization
theory, pidgin languages, substrate influences, urbanization, Solomon
Islands Pijin).
