In my previous Column (Plag 2008) I discussed the hypothesis that creoles originate as conventionalized interlanguages of an early developmental stage. For the sake of convenience I will refer to this specific hypothesis as the ‘interlanguage hypothesis’. While the idea that processes of second language acquisition (SLA) are a crucial ingredient to creole genesis is far from new or original (see Plag 2008 for some discussion and further references), it is still controversial which kinds of interlanguage processes are relevant, and how much of a given creole’s structures can be attributed to such processes. In the said Column, I took a closer look at inflectional morphology and showed that certain facts about creole languages are best explained by making reference
