In his groundbreaking 1981 book, Roots of Language, Bickerton was amongst the first to propose a list of properties that he hypothesized to be common to all creole languages. In my contribution here I revisit and reassess Bickerton's observations about the nature of negation and negative dependencies in creole languages. I will base myself more specifically on French based creoles but appeal as well to other creoles to confirm patterns discovered there or complete them with additional possibilities.
